This textbook provides an authoritative introduction to both classical and coalescent approaches to population genetics. Written for graduate students and advanced undergraduates by one of the world's leading authorities in the field, the book focuses on the theoretical background of population genetics, while emphasizing the close interplay between theory and empiricism. Traditional topics such as genetic and phenotypic variation, mutation, migration, and linkage are covered and advanced by contemporary coalescent theory, which describes the genealogy of genes in a population, ultimately connecting them to a single common ancestor. Effects of selection, particularly genomic effects, are discussed with reference to molecular genetic variation. The book is designed for students of population genetics, bioinformatics, evolutionary biology, molecular evolution, and theoretical biology--as well as biologists, molecular biologists, breeders, biomathematicians, and biostatisticians. Contains up-to-date treatment of key areas in classical and modern theoretical population genetics Provides in-depth coverage of coalescent theory Discusses genomic effects of selection Gives examples from empirical population genetics Incorporates figures, diagrams, and boxed features throughout Includes end-of-chapter exercises Speaks to a wide range of students in biology, bioinformatics, and biostatistics

Evolutionslæren beskriver livets udvikling gennem Jordens historie og gør de særeste fænomener begribelige - fra bakteriers DNA i vores celler til småborgermonogami hos solsorte og atmosfærens indhold af ilt.Denne bog giver læseren et samlet overblik over den skelsættende teori og dens udvikling. Linjen trækkes fra gennembruddet med Charles Darwins hovedværk Arternes oprindelse i 1859 og frem til den molekylære genetiks revolutionerende resultater i de seneste år. Evolutionens historie og mekanismer, arvelighedens natur, kønnets formering og evolutionært bestemte adfærdsmønstre forklares.Særligt sættes der fokus på en ofte underbelyst konsekvens af Darwins idé om naturlig selektion eller survival of the fittest: Livets udvikling er uden mål, og mennesket er derfor ikke det ypperste resultat af en lang forædlingsproces.
