What are the genomic signatures of adaptations in DNA? How often does natural selection dictate changes to DNA? How does the ebb and flow in the abundance of individuals over time get marked onto chromosomes to record genetic history? Molecular population genetics seeks to answer such questions by explaining genetic variation and molecular evolution from micro-evolutionary principles. It provides a way to learn about how evolution works and how it shapes species by incorporating molecular details of DNA as the heritable material. It enables us to understand the logic of how mutations originate, change in abundance in populations, and become fixed as DNA sequence divergence between species. With the revolutionary advances in genomic data acquisition, understanding molecular population genetics is now a fundamental requirement for today's life scientists. These concepts apply in analysis of personal genomics, genome-wide association studies, landscape and conservation genetics, forensics, molecular anthropology, and selection scans. This book introduces, in an accessible way, the bare essentials of the theory and practice of molecular population genetics.

What does it mean to say that mutation is random? How does mutation influence evolution? Are mutations merely the raw material for selection to shape adaptations? The author draws on a detailed knowledge of mutational mechanisms to argue that the randomness doctrine is best understood, not as a fact-based conclusion, but as the premise of a neo-Darwinian research program focused on selection. The successes of this research program created a blind spot - in mathematical models and verbal theories of causation - that has stymied efforts to re-think the role of variation. However, recent theoretical and empirical work shows that mutational biases can and do influence the course of evolution, in...
The Anthropocene defines the here-and-now time period on Earth of indelible (and possibly irreversible) human disturbance to the natural world, from habitat destruction and mass extinction to global climate change. To ameliorate and repair the damage that threatens the world's dwindling resources and our very existence, humanity is enacting massive interventions to fuse modern technologies with long established natural processes. Advances in genetic engineering have put us on the cusp of directly shaping the DNA of every living organism (including ourselves), as well as determining the evolution of completely novel species. The author invites the reader to explore how humans have manipulated...
In this book, Professor Ghahreman Khodadad illuminates the basis of human behavior by examining the structures that underline antisociality. The book’s central thesis is that antisocial people are so thanks to biological and neurological structures. The principle of structure to function is used to argue that the brain, without us being conscious of it, produces our behaviors. If this claim is correct, then antisocial individuals are not accountable for their antisocial behavior, and they should be treated respectfully instead of being punished. Furthermore, prisons should accordingly be converted into rehabilitation, treatment, and behavioral research centers. This is a book for the general reader who is interested in the basis of human behavior. It should also be of interest to psychologists, psychiatrists, neuroscientists, geneticists, neurobiologists, and philosophers.
An innovative view of the role of fitness concepts in evolutionary theory. Natural selection is one of the factors responsible for changes in biological populations. Some traits or organisms are fitter than others, and natural selection occurs when there are changes in the distribution of traits in populations because of fitness differences. Many philosophers of biology insist that a trait’s fitness should be defined as an average of the fitnesses of individual members of the population that have the trait. Marshall Abrams argues convincingly against this widespread approach. As he shows, it conflicts with the roles that fitness is supposed to play in evolutionary theory and with the ways ...
