Student Exploration: Unlocking the Secrets of Microevolution
Microevolution – the change in allele frequencies within a population over time – might sound intimidating, but it's a fascinating process that shapes the biodiversity we see around us. This post is your guide to exploring microevolution, designed specifically for students. We'll dissect the key concepts, explore real-world examples, and provide practical activities to deepen your understanding. Prepare to delve into the dynamic world of evolutionary biology!
What is Microevolution? A Student's Perspective
Microevolution isn't about the grand, sweeping changes that create entirely new species (that's macroevolution). Instead, it focuses on the smaller-scale shifts within a single population. These changes are driven by several key mechanisms:
Mutation: Random changes in an organism's DNA sequence. These mutations can introduce new alleles (different versions of a gene) into the population.
Gene Flow: The movement of genes between populations. Migration, for example, can introduce new alleles or alter the frequencies of existing ones.
Genetic Drift: Random fluctuations in allele frequencies, particularly impactful in small populations. Imagine a population of beetles where a random event wipes out most of the green beetles – the allele for green color becomes less frequent purely by chance.
Natural Selection: The differential survival and reproduction of individuals based on their traits. Individuals with advantageous traits are more likely to pass on their genes, leading to a shift in allele frequencies over generations.
Exploring Microevolution Through Engaging Activities
Understanding abstract concepts like microevolution requires hands-on learning. Here are some engaging activities ideal for student exploration:
1. The Peppered Moth Simulation: This classic example perfectly illustrates natural selection. Students can simulate the changing environment (industrial pollution darkening tree bark) and track how the frequency of light and dark-colored moths shifts over time. This activity highlights how environmental pressures drive evolutionary change.
2. Bacterial Resistance Simulation: Using readily available materials (like different colored beads representing antibiotic-resistant and non-resistant bacteria), students can model the development of antibiotic resistance in bacterial populations. This simulation demonstrates the rapid pace of microevolution in organisms with short generation times.
3. Hardy-Weinberg Equilibrium: This principle provides a baseline to understand how allele frequencies should remain constant in the absence of evolutionary forces. By calculating allele and genotype frequencies using the Hardy-Weinberg equation (p² + 2pq + q² = 1), students can compare theoretical expectations with real-world data, revealing the impact of evolutionary mechanisms.
Real-World Examples of Microevolution
Microevolution isn't confined to textbooks; it's happening all around us:
Antibiotic Resistance in Bacteria: This is perhaps the most well-known example. Overuse of antibiotics has driven the evolution of resistant strains, posing a serious threat to human health.
Pesticide Resistance in Insects: Similar to antibiotic resistance, the widespread use of pesticides has led to the evolution of resistant insect populations, requiring the development of new and more potent chemicals.
Darwin's Finches: The diverse beak shapes of Darwin's finches on the Galapagos Islands provide a compelling example of how natural selection has shaped populations based on available food sources.
Human Evolution: Our own species continues to evolve, albeit slowly, with ongoing changes in allele frequencies driven by factors like disease resistance and environmental adaptation.
Analyzing Data and Drawing Conclusions
To fully grasp microevolution, students must be able to analyze data and draw meaningful conclusions. This involves:
Interpreting graphs and charts: Visual representations of allele frequency changes over time are crucial for understanding the dynamics of microevolution.
Statistical analysis: Basic statistical tests can be used to determine if observed changes in allele frequencies are statistically significant.
Critical thinking: Students need to analyze data critically, considering potential biases and limitations in the data collection methods.
Conclusion
Understanding microevolution is fundamental to understanding the broader picture of evolution. By engaging in hands-on activities, analyzing real-world examples, and developing strong analytical skills, students can unlock the secrets of this fascinating process and gain a deeper appreciation for the dynamic nature of life on Earth. This exploration is not just about memorizing facts; it's about developing a scientific mindset and the ability to critically analyze and interpret biological data.
FAQs
1. What's the difference between microevolution and macroevolution? Microevolution refers to changes within a population's gene pool, while macroevolution encompasses larger-scale evolutionary changes, such as the formation of new species.
2. Can microevolution be reversed? While allele frequencies can shift, reversing a major microevolutionary change is usually difficult, particularly if it involves significant environmental changes or genetic drift in a small population.
3. How does microevolution contribute to biodiversity? Microevolutionary changes accumulate over time and, coupled with other evolutionary processes, contribute to the vast array of species we see today.
4. Are humans still evolving through microevolution? Yes, human populations are still subject to microevolutionary forces, although the pace is slower than in some other organisms.
5. What are some ethical considerations related to understanding microevolution? The understanding of microevolution is crucial for tackling issues like antibiotic resistance and the conservation of endangered species. Ethical considerations arise in the application of this knowledge, including responsible antibiotic use and the ethical implications of genetic engineering.

| student exploration microevolution: Evolution Challenges Karl S. Rosengren, 2012-04-25 This book goes beyond the science versus religion dispute to ask why evolution is so often rejected as a legitimate scientific fact, focusing on a wide range of cognitive, socio-cultural, and motivational factors that make concepts such as evolution difficult to grasp. |
| student exploration microevolution: Science's Blind Spot Cornelius Hunter, 2007-06-01 Had evolutionists been in charge, they wouldn't have made the mosquito, planetary orbits would align perfectly, and the human eye would be better designed. But they tend to gloss over their own failed predictions and faulty premises. Naturalists see Darwin's theories as logical and that's enough. To think otherwise brands you a heretic to all things wise and rational. Science's Blind Spot takes the reader on an enlightening journey through the ever-evolving theory of evolution. Cornelius G. Hunter goes head-to-head with those who twist textbooks, confuse our children, and reject all challengers before they can even speak. This fascinating, fact-filled resource opens minds to nature in a way that both seeks and sees the intelligent design behind creation's masterpieces. |

| student exploration microevolution: Darwin-Inspired Learning Carolyn J. Boulter, Michael J. Reiss, Dawn L. Sanders, 2015-01-19 Charles Darwin has been extensively analysed and written about as a scientist, Victorian, father and husband. However, this is the first book to present a carefully thought out pedagogical approach to learning that is centered on Darwin’s life and scientific practice. The ways in which Darwin developed his scientific ideas, and their far reaching effects, continue to challenge and provoke contemporary teachers and learners, inspiring them to consider both how scientists work and how individual humans ‘read nature’. Darwin-inspired learning, as proposed in this international collection of essays, is an enquiry-based pedagogy, that takes the professional practice of Charles Darwin as its source. Without seeking to idealise the man, Darwin-inspired learning places importance on: • active learning • hands-on enquiry • critical thinking • creativity • argumentation • interdisciplinarity. In an increasingly urbanised world, first-hand observations of living plants and animals are becoming rarer. Indeed, some commentators suggest that such encounters are under threat and children are living in a time of ‘nature-deficit’. Darwin-inspired learning, with its focus on close observation and hands-on enquiry, seeks to re-engage children and young people with the living world through critical and creative thinking modeled on Darwin’s life and science. |

Stock, 2011-06-24 A holistic and comprehensive account of the nature of the transition from hunting to farming in prehistory. It addresses for the first time the main bioarchaeological aspects such as changes in mobility, behaviour, diet and population dynamics. This book is of major interest to the relevant audience since it offers for the first time a global perspective on the bioarchaeology of the transition to agriculture. It includes contributions from world-class researchers, with a particular emphasis on advances in methods (e.g. ancient DNA of pathogens, stable isotope analysis, etc.). The book specifically addresses the following aspects associated with the transition to agriculture in various world regions: Changes in adult and subadult stature and subadult growth profiles Diachronic trends in the analysis of functional morphological structures (craniofacial, vault, lower limbs, etc.) and whether these are associated with change in overall sex-specific morphological variability Changes in mobility Changes in behaviour which can be reconstructed from the study of the skeletal record. These include changes in activity patterns, sexual dimorphism, evidence of inter-personal trauma, and the like. Population dynamics and microevolution by examining intra and inter population variations in dental and cranial metric traits, as well as archaeogenetic studies of ancient DNA (e.g. mtDNA markers). |
| student exploration microevolution: Lizards in an Evolutionary Tree Jonathan B. Losos, 2011-02-09 In a book both beautifully illustrated and deeply informative, Jonathan Losos, a leader in evolutionary ecology, celebrates and analyzes the diversity of the natural world that the fascinating anoline lizards epitomize. Readers who are drawn to nature by its beauty or its intellectual challenges—or both—will find his book rewarding.—Douglas J. Futuyma, State University of New York, Stony Brook This book is destined to become a classic. It is scholarly, informative, stimulating, and highly readable, and will inspire a generation of students.—Peter R. Grant, author of How and Why Species Multiply: The Radiation of Darwin's Finches Anoline lizards experienced a spectacular adaptive radiation in the dynamic landscape of the Caribbean islands. The radiation has extended over a long period of time and has featured separate radiations on the larger islands. Losos, the leading active student of these lizards, presents an integrated and synthetic overview, summarizing the enormous and multidimensional research literature. This engaging book makes a wonderful example of an adaptive radiation accessible to all, and the lavish illustrations, especially the photographs, make the anoles come alive in one's mind.—David Wake, University of California, Berkeley This magnificent book is a celebration and synthesis of one of the most eventful adaptive radiations known. With disarming prose and personal narrative Jonathan Losos shows how an obsession, beginning at age ten, became a methodology and a research plan that, together with studies by colleagues and predecessors, culminated in many of the principles we now regard as true about the origins and maintenance of biodiversity. This work combines rigorous analysis and glorious natural history in a unique volume that stands with books by the Grants on Darwin's finches among the most informed and engaging accounts ever written on the evolution of a group of organisms in nature.—Dolph Schluter, author of The Ecology of Adaptive Radiation |
| student exploration microevolution: Cognition and Instruction Sharon M. Carver, David Klahr, 2013-06-17 This volume is based on papers presented at the 30th Carnegie Mellon Symposium on Cognition. This particular symposium was conceived in reference to the 1974 symposium entitled Cognition and Instruction. In the 25 years since that symposium, reciprocal relationships have been forged between psychology and education, research and practice, and laboratory and classroom learning contexts. Synergistic advances in theories, empirical findings, and instructional practice have been facilitated by the establishment of new interdisciplinary journals, teacher education courses, funding initiatives, and research institutes. So, with all of this activity, where is the field of cognition and instruction? How much progress has been made in 25 years? What remains to be done? This volume proposes and illustrates some exciting and challenging answers to these questions. Chapters in this volume describe advances and challenges in four areas, including development and instruction, teachers and instructional strategies, tools for learning from instruction, and social contexts of instruction and learning. Detailed analyses of tasks, subjects' knowledge and processes, and the changes in performance over time have led to new understanding of learners' representations, their use of multiple strategies, and the important role of metacognitive processes. New methods for assessing and tracking the development and elaboration of knowledge structures and processing strategies have yielded new conceptualizations of the process of change. Detailed cognitive analysis of expert teachers, as well as a direct focus on enhancing teachers' cognitive models of learners and use of effective instructional strategies, are other areas that have seen tremendous growth and refinement in the past 25 years. Similarly, the strong impact of curriculum materials and activities based on a thorough cognitive analysis of the task has been extended to the use of technological tools for learning, such as intelligent tutors and complex computer based instructional interfaces. Both the shift to conducting a significant portion of the cognition and instruction research in real classrooms and the increased collaboration between academics and educators have brought the role of the social context to center stage. |

| student exploration microevolution: Darwin's Doubt Stephen C. Meyer, 2013-06-18 When Charles Darwin finished The Origin of Species, he thought that he had explained every clue, but one. Though his theory could explain many facts, Darwin knew that there was a significant event in the history of life that his theory did not explain. During this event, the “Cambrian explosion,” many animals suddenly appeared in the fossil record without apparent ancestors in earlier layers of rock. In Darwin’s Doubt, Stephen C. Meyer tells the story of the mystery surrounding this explosion of animal life—a mystery that has intensified, not only because the expected ancestors of these animals have not been found, but because scientists have learned more about what it takes to construct an animal. During the last half century, biologists have come to appreciate the central importance of biological information—stored in DNA and elsewhere in cells—to building animal forms. Expanding on the compelling case he presented in his last book, Signature in the Cell, Meyer argues that the origin of this information, as well as other mysterious features of the Cambrian event, are best explained by intelligent design, rather than purely undirected evolutionary processes. |
| student exploration microevolution: Model-Based Demography Thomas K. Burch, 2017-10-14 Late in a career of more than sixty years, Thomas Burch, an internationally known social demographer, undertook a wide-ranging methodological critique of demography. This open access volume contains a selection of resulting papers, some previously unpublished, some published but not readily accessible [from past meetings of The International Union for the Scientific Study of Population and its research committees, or from other small conferences and seminars]. Rejecting the idea that demography is simply a branch of applied statistics, his work views it as an autonomous and complete scientific discipline. When viewed from the perspective of modern philosophy of science, specifically the semantic or model-based school, demography is a balanced discipline, with a rich body of techniques and data, but also with more and better theories than generally recognized. As demonstrated in this book, some demographic techniques can also be seen as theoretical models, and some substantive/behavioral models, commonly rejected as theory because of inconsistent observations, are now seen as valuable theoretical models, for example demographic transition theory. This book shows how demography can build a strong theoretical edifice on its broad and deep empirical foundation by adoption of the model-based approach to science. But the full-fruits of this approach will require demographers to make greater use of computer modeling [both macro- and micro-simulation], in the statement and manipulation of theoretical ideas, as well as for numerical computation.

| student exploration microevolution: Evolutionary Game Theory, Natural Selection, and Darwinian Dynamics Thomas L. Vincent, Joel S. Brown, 2012-08-16 All of life is a game, and evolution by natural selection is no exception. The evolutionary game theory developed in this 2005 book provides the tools necessary for understanding many of nature's mysteries, including co-evolution, speciation, extinction and the major biological questions regarding fit of form and function, diversity, procession, and the distribution and abundance of life. Mathematics for the evolutionary game are developed based on Darwin's postulates leading to the concept of a fitness generating function (G-function). G-function is a tool that simplifies notation and plays an important role developing Darwinian dynamics that drive natural selection. Natural selection may result in special outcomes such as the evolutionarily stable strategy (ESS). An ESS maximum principle is formulated and its graphical representation as an adaptive landscape illuminates concepts such as adaptation, Fisher's Fundamental Theorem of Natural Selection, and the nature of life's evolutionary game. |

| student exploration microevolution: The Oxford Handbook of Evolutionary Medicine Martin Brüne, Wulf Schiefenhövel, 2019-01-31 Medicine is grounded in the natural sciences, where biology stands out with regard to our understanding of human physiology and the conditions that cause dysfunction. Ironically though, evolutionary biology is a relatively disregarded field. One reason for this omission is that evolution is deemed a slow process. Indeed, the macroanatomical features of our species have changed very little in the last 300,000 years. A more detailed look, however, reveals that novel ecological contingencies, partly in relation to cultural evolution, have brought about subtle changes pertaining to metabolism and immunology, including adaptations to dietary innovations, as well as adaptations to the exposure to novel pathogens. Rapid pathogen evolution and evolution of cancer cells cause major problems for the immune system. Moreover, many adaptations to past ecologies have actually turned into risk factors for somatic disease and psychological disorder in our modern worlds (i.e. mismatch), among which epidemics of autoimmune diseases, cardiovascular diseases, diabetes and obesity, as well as several forms of cancer stand out. One could add depression, anxiety, and other psychiatric conditions to the list. The Oxford Handbook of Evolutionary Medicine is a compilation of up-to-date insights into the evolutionary history of ourselves as a species, exploring how and why our evolved design may convey vulnerability to disease. Written in a classic textbook style emphasising physiology and pathophysiology of all major organ systems, the Oxford Handbook of Evolutionary Medicine is valuable reading for students as well as scholars in the fields of medicine, biology, anthropology and psychology. |
| student exploration microevolution: Systematics, Evolution, and Biogeography of Compositae Vicki Ann Funk, 2009 This spectacular book does full justice to the Compositae (Asteraceae), the largest and most successful flowering plant family with some 1700 genera and 24,000 species. It is an indispensable reference, providing the most up-to-date hypotheses of phylogenetic relationships in the family based on molecular and morphological characters, along with the corresponding subfamilial and tribal classification. The 2009 work not only integrates the extensive molecular phylogenetic analyses conducted in the last 25 years, but also uses these to produce a metatree for about 900 taxa of Compositae. The book contains 44 chapters, contributed by 80 authors, covering the history, economic importance, character variation, and systematic and phylogenetic diversity of the family. The emphasis of this work is phylogenetic; its chapters provide a detailed, current, and thoroughly documented presentation of the major (and not so major) clades in the family, citing some 2632 references. Like the Compositae, the book is massive, diverse, and fascinating. It is beautifully illustrated, with 170 figures, and an additional 108 cladograms (all consistently color-coded, based on the geographic range of the included taxa); within these figures are displayed 443 color photographs, clearly demonstrating the amazing array of floral and vegetative form expressed by members of the clade. --NHBS Environment Bookstore. |
| student exploration microevolution: Evolution and Genetics in Life Histories H. Dingle, J. P. Hegmann, 2012-12-06 This volume is the result of a symposium entitled Variation in Life Histories: Genetics and Evolutionary Processes sponsored by the Program in Evolutionary Ecology and Behavior of the University of Iowa and held in Iowa City on October 13 and 14, 1980. Prompted by a recent upsurge of interest in the evolution of life histories, we chose this topic because of the obvious association between life history traits and Darwinian fit ness. If such an association were to be fruitfully investigated, it would require the closer cooperation of population and evolutionary ecologists and quantitative and population geneticists. To encourage such an association, our symposium had four major aims: first, to facilitate intellectual exchange across disciplines among an array of biologists studying life histories; second, to encourage exploration of genetic variance and covari ance for life history traits; third, to consider the ecological background for genetic vari ability; and finally, to facilitate a comparative overview both within and among species. Obviously such broad aims cannot be met totally in a single volume, but we think we have succeeded reasonably well in providing a representative and nourishing intel lectual feast. We see this book as a stimulus to the coordination of future efforts in an important and expanding area of inquiry. We have divided the book into six sections. |

| student exploration microevolution: Multiple Representations in Biological Education David F. Treagust, Chi-Yan Tsui, 2013-02-01 This new publication in the Models and Modeling in Science Education series synthesizes a wealth of international research on using multiple representations in biology education and aims for a coherent framework in using them to improve higher-order learning. Addressing a major gap in the literature, the volume proposes a theoretical model for advancing biology educators’ notions of how multiple external representations (MERs) such as analogies, metaphors and visualizations can best be harnessed for improving teaching and learning in biology at all pedagogical levels. The content tackles the conceptual and linguistic difficulties of learning biology at each level—macro, micro, sub-micro, and symbolic, illustrating how MERs can be used in teaching across these levels and in various combinations, as well as in differing contexts and topic areas. The strategies outlined will help students’ reasoning and problem-solving skills, enhance their ability to construct mental models and internal representations, and, ultimately, will assist in increasing public understanding of biology-related issues, a key goal in today’s world of pressing concerns over societal problems about food, environment, energy, and health. The book concludes by highlighting important aspects of research in biological education in the post-genomic, information age. |
| student exploration microevolution: The Case for Faith Student Edition Lee Strobel, 2010-02-23 Prepare yourself for an eye-opening, no-punches-pulled investigation into eight of the toughest objections to Christianity. The answers will prove whether or not Jesus is who he says he is and if heaven is for real, leading you to a life-changing decision in your current case for or against Christianity. Like you, as a student, Lee Strobel asked the same tough questions you face about God, about Jesus, about science, and about Christianity. Why is there suffering? Doesn’t science disprove miracles? What about hell—and the millions who’ve never heard of Jesus? Is heaven for real? Is God unjust? So what convinced Lee Strobel—an atheist investigative journalist turned faith-filled Christian—that Jesus is real? Join Lee in this fascinating journey of discovery. If you’re an atheist or just aren’t sure about Jesus, these stories will turn your whole world upside down. If you’re already a Christian, you’ll gain powerful insights that will reshape your understanding of the Bible and affect your life of faith like never before. |
| student exploration microevolution: Continuities in Cultural Evolution Margaret Mead, 2017-07-12 Margaret Mead once said, I have spent most of my life studying the lives of other peoples--faraway peoples--so that Americans might better understand themselves. Continuities in Cultural Evolution is evidence of this devotion. All of Mead's efforts were intended to help others learn about themselves and work toward a more humane and socially responsible society. Scientist, writer, explorer, and teacher, Mead brought the serious work of anthropology into the public consciousness. This volume began as the Terry Lectures, given at Yale in 1957 and was not published until 1964, after extensive reworking. The time she spent on revision is evidence of the importance Mead attached to the subject: the need to develop a truly evolutionary vision of human culture and society. This was desirable in her eyes both in order to reinforce the historical dimension in our ideas about human culture, and to preserve the relevance of historical and cultural diversity to social, economic, and political action. Given the present state of academic and public discourse alike, this volume speaks to us in a language we badly need to recover. |

| student exploration microevolution: Conservation Biology for All Navjot S. Sodhi, Paul R. Ehrlich, 2010-01-08 Conservation Biology for All provides cutting-edge but basic conservation science to a global readership. A series of authoritative chapters have been written by the top names in conservation biology with the principal aim of disseminating cutting-edge conservation knowledge as widely as possible. Important topics such as balancing conversion and human needs, climate change, conservation planning, designing and analyzing conservation research, ecosystem services, endangered species management, extinctions, fire, habitat loss, and invasive species are covered. Numerous textboxes describing additional relevant material or case studies are also included. The global biodiversity crisis is now unstoppable; what can be saved in the developing world will require an educated constituency in both the developing and developed world. Habitat loss is particularly acute in developing countries, which is of special concern because it tends to be these locations where the greatest species diversity and richest centres of endemism are to be found. Sadly, developing world conservation scientists have found it difficult to access an authoritative textbook, which is particularly ironic since it is these countries where the potential benefits of knowledge application are greatest. There is now an urgent need to educate the next generation of scientists in developing countries, so that they are in a better position to protect their natural resources. |
| student exploration microevolution: Archaeology, Anthropology, and Interstellar Communication National Aeronautics Administration, Douglas Vakoch, 2014-09-06 Addressing a field that has been dominated by astronomers, physicists, engineers, and computer scientists, the contributors to this collection raise questions that may have been overlooked by physical scientists about the ease of establishing meaningful communication with an extraterrestrial intelligence. These scholars are grappling with some of the enormous challenges that will face humanity if an information-rich signal emanating from another world is detected. By drawing on issues at the core of contemporary archaeology and anthropology, we can be much better prepared for contact with an extraterrestrial civilization, should that day ever come. |

| student exploration microevolution: Compendium for Early Career Researchers in Mathematics Education Gabriele Kaiser, Norma Presmeg, 2019-04-26 The purpose of this Open Access compendium, written by experienced researchers in mathematics education, is to serve as a resource for early career researchers in furthering their knowledge of the state of the field and disseminating their research through publishing. To accomplish this, the book is split into four sections: Empirical Methods, Important Mathematics Education Themes, Academic Writing and Academic Publishing, and a section Looking Ahead. The chapters are based on workshops that were presented in the Early Career Researcher Day at the 13th International Congress on Mathematical Education (ICME-13). The combination of presentations on methodological approaches and theoretical perspectives shaping the field in mathematics education research, as well as the strong emphasis on academic writing and publishing, offered strong insight into the theoretical and empirical bases of research in mathematics education for early career researchers in this field. Based on these presentations, the book provides a state-of-the-art overview of important theories from mathematics education and the broad variety of empirical approaches currently widely used in mathematics education research. This compendium supports early career researchers in selecting adequate theoretical approaches and adopting the most appropriate methodological approaches for their own research. Furthermore, it helps early career researchers in mathematics education to avoid common pitfalls and problems while writing up their research and it provides them with an overview of the most important journals for research in mathematics education, helping them to select the right venue for publishing and disseminating their work. |

| student exploration microevolution: On the Origin of Species Illustrated Charles Darwin, 2020-12-04 On the Origin of Species (or, more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life),[3] published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology.[4] Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation. |

| student exploration microevolution: Time of Nature and the Nature of Time Christophe Bouton, Philippe Huneman, 2017-05-30 This volume addresses the question of time from the perspective of the time of nature. Its aim is to provide some insights about the nature of time on the basis of the different uses of the concept of time in natural sciences. Presenting a dialogue between philosophy and science, it features a collection of papers that investigate the representation, modeling and understanding of time as they appear in physics, biology, geology and paleontology. It asks questions such as: whether or not the notions of time in the various sciences are reducible to the same physical time, what status should be given to timescale differences, or what are the specific epistemic issues raised by past facts in natural sciences. The book first explores the experience of time and its relation to time in nature in a set of chapters that bring together what human experience and physics enable metaphysicians, logicians and scientists to say about time. Next, it studies time in physics, including some puzzling paradoxes about time raised by the theory of relativity and quantum mechanics. The volume then goes on to examine the distinctive problems and conceptions of time in the life sciences. It explores the concept of deep time in paleontology and geology, time in the epistemology of evolutionary biology, and time in developmental biology. Each scientific discipline features a specific approach to time and uses distinctive methodologies for implementing time in its models. This volume seeks to define a common language to conceive of the distinct ways different scientific disciplines view time. In the process, it offers a new approach to the issue of time that will appeal to a wide range of readers: philosophers and historians of science, metaphysicians and natural scientists - be they scholars, advanced students or readers from an educated general audience. |
| student exploration microevolution: The Cognitive-Theoretic Model of the Universe: A New Kind of Reality Theory Christopher Michael Langan, 2002-06-01 Paperback version of the 2002 paper published in the journal Progress in Information, Complexity, and Design (PCID). ABSTRACT Inasmuch as science is observational or perceptual in nature, the goal of providing a scientific model and mechanism for the evolution of complex systems ultimately requires a supporting theory of reality of which perception itself is the model (or theory-to-universe mapping). Where information is the abstract currency of perception, such a theory must incorporate the theory of information while extending the information concept to incorporate reflexive self-processing in order to achieve an intrinsic (self-contained) description of reality. This extension is associated with a limiting formulation of model theory identifying mental and physical reality, resulting in a reflexively self-generating, self-modeling theory of reality identical to its universe on the syntactic level. By the nature of its derivation, this theory, the Cognitive Theoretic Model of the Universe or CTMU, can be regarded as a supertautological reality-theoretic extension of logic. Uniting the theory of reality with an advanced form of computational language theory, the CTMU describes reality as a Self Configuring Self-Processing Language or SCSPL, a reflexive intrinsic language characterized not only by self-reference and recursive self-definition, but full self-configuration and self-execution (reflexive read-write functionality). SCSPL reality embodies a dual-aspect monism consisting of infocognition, self-transducing information residing in self-recognizing SCSPL elements called syntactic operators. The CTMU identifies itself with the structure of these operators and thus with the distributive syntax of its self-modeling SCSPL universe, including the reflexive grammar by which the universe refines itself from unbound telesis or UBT, a primordial realm of infocognitive potential free of informational constraint. Under the guidance of a limiting (intrinsic) form of anthropic principle called the Telic Principle, SCSPL evolves by telic recursion, jointly configuring syntax and state while maximizing a generalized self-selection parameter and adjusting on the fly to freely-changing internal conditions. SCSPL relates space, time and object by means of conspansive duality and conspansion, an SCSPL-grammatical process featuring an alternation between dual phases of existence associated with design and actualization and related to the familiar wave-particle duality of quantum mechanics. By distributing the design phase of reality over the actualization phase, conspansive spacetime also provides a distributed mechanism for Intelligent Design, adjoining to the restrictive principle of natural selection a basic means of generating information and complexity. Addressing physical evolution on not only the biological but cosmic level, the CTMU addresses the most evident deficiencies and paradoxes associated with conventional discrete and continuum models of reality, including temporal directionality and accelerating cosmic expansion, while preserving virtually all of the major benefits of current scientific and mathematical paradigms. |

| student exploration microevolution: Deliver Us from Evolution? Aaron R. Yilmaz, 2016-12-10 Is evolution an enemy to faith? Can God, Scripture, and science be reconciled? What evidence is there for evolution? Is it true? In this tour de force of scientific rigor and biblical insight, biologist Aaron Yilmaz examines the Creation vs. Evolution controversy from a scientific and biblical perspective, undergirded with psychological and philosophical understanding. With over 600 citations from peer-reviewed scientific journals, books, and university literature, he objectively and exhaustively investigates the evidence for not only an ancient earth but for the reality of evolution. With humility, humor, and wit, Yilmaz presents a surprising harmony between science and God, far more satisfying than Creationism or Intelligent Design. This fast-paced and engaging book powerfully demonstrates how science and faith, when properly understood, do not conflict and on the contrary lead to a deeper appreciation of God and a more intellectually fulfilling and spiritually rewarding life. Aaron R. Yilmaz holds an M.S. in Biology from the University of Saint Joseph, West Hartford, Connecticut (2015), and a B.S. in Biology with departmental honors from Oakland University, Rochester, Michigan (2013). He has formally studied evolution at both the undergraduate and graduate levels, performed research leading to peer-reviewed published scientific literature, and has taught biology at the college level. |
