  • Part III: Evolutionary Processes, which explains how the diversity of life is generated by various sources of variation and mechanisms of adaptation, such as mutation, recombination, gene flow, genetic drift, natural selection, sexual selection, kin selection, and coevolution.



  • Part IV: Human Evolution, which discusses human evolution and diversity from both paleontological and molecular perspectives, as well as the implications of evolutionary methods for understanding human health and disease.



In addition to these four parts, the book also includes two online-only chapters that deal with techniques and models used in studying evolutionary biology, such as phylogenetic reconstruction methods and population genetics models. These chapters can be accessed from the book's website (www.evolution-textbook.org), which also contains other supplementary materials for instructors and students, such as downloadable figures, chapter problems, sample chapters, exam copies, and updates.


Part I: The History and Evidence of Evolution




The development of evolutionary ideas from Darwin to molecular biology




The first chapter of this part provides an account of how the ideas underpinning evolutionary theory developed over time from ancient times to modern times. It traces the historical roots of evolutionary thinking in various cultures and civilizations, such as Greece, India, China, Islam, and Europe. It also highlights the contributions of some of the most influential figures in the history of evolutionary biology, such as Aristotle, Lamarck, Lyell, Wallace, Darwin, Mendel, Haldane, Fisher, Wright, Dobzhansky, Mayr, Simpson, Huxley, Watson, Crick, and Woese. It also examines some of the major experiments and ideas that shaped the development of molecular biology, such as the Miller-Urey experiment, the central dogma, the genetic code, the operon model, and the endosymbiotic theory.


The main sources of evidence for evolution: fossils, biogeography, comparative anatomy, embryology, molecular data




The challenges and controversies faced by evolutionary theory: creationism, intelligent design, sociobiology




The third chapter of this part discusses some of the challenges and controversies that evolutionary theory has faced and continues to face from various perspectives and disciplines. It analyzes the arguments and evidence of creationism and intelligent design, two movements that reject or question the validity of evolution and propose alternative explanations for the origin and diversity of life based on supernatural or intelligent causes. It also evaluates the claims and criticisms of sociobiology, a branch of biology that applies evolutionary principles to the study of social behavior and culture in humans and other animals.


Part II: The Origin and Diversification of Life




The origin of life: hypotheses, experiments, and scenarios




The fourth chapter of this part explores one of the most intriguing and unresolved questions in biology: how did life originate on Earth? It reviews some of the main hypotheses, experiments, and scenarios that have been proposed to explain the origin of life, such as the primordial soup hypothesis, the iron-sulfur world hypothesis, the RNA world hypothesis, the metabolism-first hypothesis, and the panspermia hypothesis. It also discusses some of the challenges and limitations of these approaches, such as the lack of direct evidence, the difficulty of reproducing prebiotic conditions, and the complexity of defining life.


The major transitions in evolution: from prokaryotes to eukaryotes, from unicellular to multicellular, from asexual to sexual reproduction




The fifth chapter of this part describes some of the major transitions in evolution that have resulted in fundamental changes in the genetic organization and biological complexity of organisms. It explains how prokaryotes evolved into eukaryotes by acquiring membrane-bound organelles through endosymbiosis. It also explains how unicellular organisms evolved into multicellular organisms by developing cell differentiation and cooperation. It also explains how asexual reproduction evolved into sexual reproduction by introducing genetic recombination and variation.


The diversity of life: the tree of life, the three domains of life, the major groups of organisms




The sixth chapter of this part presents an overview of the diversity of life on Earth, from its origin to its present state. It introduces the concept of the tree of life, which represents the evolutionary relationships among all living organisms based on their common ancestry. It also introduces the classification of life into three domains: Bacteria, Archaea, and Eukarya. It also introduces some of the major groups of organisms within each domain, such as cyanobacteria, methanogens, protists, fungi, plants, animals, etc.


The evolution of humans: the fossil record, the molecular evidence, the behavioral and cultural traits




The seventh chapter of this part focuses on the evolution of humans, one of the most fascinating and controversial topics in evolutionary biology. It summarizes the fossil record of human evolution, from the earliest hominins to modern humans. It also summarizes the molecular evidence of human evolution, from mitochondrial DNA to genome-wide comparisons. It also summarizes some of the behavioral and cultural traits that distinguish humans from other primates, such as bipedalism, brain size, language, tool use, art, religion, etc.


Part III: Evolutionary Processes




The sources of variation: mutation, recombination, gene flow, genetic drift




The eighth chapter of this part explains how variation arises in populations and species as a result of various processes that affect their genetic makeup. It defines mutation as a change in DNA sequence that can introduce new alleles or modify existing ones. It defines recombination as a process that shuffles alleles during meiosis or DNA repair. It defines gene flow as a process that transfers alleles between populations through migration or hybridization. It defines genetic drift as a process that changes allele frequencies due to random sampling effects.


The mechanisms of adaptation: natural selection, sexual selection, kin selection, coevolution




The ninth chapter of this part explains how adaptation occurs in populations and species as a result of various mechanisms that affect their fitness and survival. It defines natural selection as a process that favors alleles or traits that increase reproductive success in a given environment. It defines sexual selection as a process that favors alleles or traits that increase mating success in a given population. It defines kin selection as a process that favors alleles or traits that increase indirect fitness through helping relatives. It defines coevolution as a process that involves reciprocal adaptation between interacting species.


The patterns of evolution: speciation, phylogeny, macroevolution, convergent evolution




The tenth chapter of this part explains how evolution produces different patterns and outcomes at different levels and scales of biological organization. It defines speciation as a process that leads to the formation of new species from existing ones. It defines phylogeny as a representation of the evolutionary history and relationships of organisms based on their common ancestry. It defines macroevolution as a term that refers to large-scale evolutionary changes that occur over long periods of time. It defines convergent evolution as a phenomenon that occurs when unrelated organisms evolve similar traits due to similar selective pressures.


Part IV: Human Evolution




The origin of modern humans: the Out-of-Africa and multiregional hypotheses




The eleventh chapter of this part discusses one of the most debated and controversial issues in human evolution: the origin of modern humans. It compares and contrasts two competing hypotheses that have been proposed to explain the origin and dispersal of modern humans: the Out-of-Africa hypothesis and the multiregional hypothesis. The Out-of-Africa hypothesis proposes that modern humans originated in Africa and then migrated to other regions, replacing or interbreeding with other hominin populations. The multiregional hypothesis proposes that modern humans originated in multiple regions from local populations of archaic humans, with gene flow and natural selection maintaining their unity.


The genetic diversity of humans: the molecular markers, the geographic patterns, the evolutionary implications




The twelfth chapter of this part explores the genetic diversity of humans, which reflects their evolutionary history and diversity. It introduces some of the molecular markers that are used to study human genetic variation, such as mitochondrial DNA, Y-chromosome DNA, autosomal DNA, and single nucleotide polymorphisms (SNPs). It also describes some of the geographic patterns of human genetic variation, such as the African origin, the out-of-Africa bottleneck, the regional differentiation, and the recent admixture. It also discusses some of the evolutionary implications of human genetic variation, such as the molecular clock, the genetic basis of phenotypic traits, and the genetic susceptibility to diseases.


The evolutionary medicine: the genetic diseases, the infectious diseases, the drug resistance




The thirteenth chapter of this part examines the applications and implications of evolutionary principles and methods for understanding human health and disease. It introduces the concept of evolutionary medicine, which is an interdisciplinary field that uses evolutionary perspectives to explain the causes and consequences of human diseases. It also illustrates some of the topics and examples of evolutionary medicine, such as the genetic diseases, the infectious diseases, and the drug resistance.
