Evolution Genetics Population

Researchers are increasingly turning to genetic data to help decipher the origins of modern humanity. Did we arise as a new species in Africa 200,000 years ago and then replace human populations outside of Africa (African replacement), or are we part of a single, evolving lineage extending back perhaps as far as two million years ago (multiregional evolution)? Genetics and the Search for Modern Human Origins is an introduction to the genetic evidence of modern human origins, including what it can show us about prehistory, population size, and migration. Weighing the various debates, the author argues for a multiregional view that our recent origins are mostly, but not exclusively, out of Africa. Taking into consideration the ongoing debate over modern human origins, this book offers a fascinating and educated look into the concepts, methods, and interpretations of human origins without weighing down the text with advanced mathematics or excessively technical language. John Relethford, a highly acclaimed author, provides a clear and concise review of how genetic data is used to study modern human origins. Topics discussed in Genetics and the Search for Modern Human Origins include: Evolution and genetic history" Mitochondrial Eve" Genetic diversity and recent human evolutionGenetic differences between human populationsReconstructing ancient demography Neandertal DNASummary of the genetic evidence Genetics and the Search for Modern Human Origins is an engaging and informative resource for anyone interested in genetics, evolution, and human origins.

This concise introduction offers students and researchers an overview of the discipline that connects genetics and evolution. Addressing the theories behind population genetics and relevant empirical evidence, John Gillespie discusses genetic drift, natural selection, nonrandom mating, quantitative genetics, and the evolutionary advantage of sex. First published to wide acclaim in 1998, this brilliant primer has been updated to include new sections on molecular evolution, genetic drift, genetic load, the stationary distribution, and two-locus dynamics. This book is indispensable for students working in a laboratory setting or studying free-ranging populations.

Evolution in Mendelian Populations - Evolution in Mendelian Populations is a lengthy 1931 scientific paper on evolution by the American population geneticist Sewall Wright, published in Genetics volume 16, pages 97-126. In it, Wright outlines various concepts including genetic drift, effective population size and inbreeding.

Genetic evolution - Genetic evolution refers to the change in gene frequency, which is the frequency of alleles in a breeding population from generation to generation. This term is used by population genetics for a more specific definition than the one given for the term evolution (“descent with modification over the generations”).

Michael Lynch (genetics) - Michael Lynch is Distinguished Professor of Evolution, Population Genetics and Genomics at Indiana University. Besides many highly acclaimed papers, especially in population genetics, he has written a two volume textbook with Bruce Walsh, widely considered the "Bible" of quantitative genetics.

Peppered moth evolution - The evolution of the peppered moth over the last two hundred years has been studied in detail. Evolution, more specifically microevolution is defined at the operational level as "a change in the frequency of an allele within a gene pool" (Dobzhansky, 1937); see population genetics.
