Origins and genomic perspectives on animal domestication

Apuntes

THE IMPACT OF DOMESTICATION AND BREEDING PRACTICES IN THE GENOMIC COMPOSITION OF ANIMAL SPECIES ASKING SIMPLE QUESTIONS TO EXPLAIN COMPLEX DEMOGRAPHIC SCENARIOS Catarina Ginja First chapter of the Origin of Species devoted to Variation under Domestication " A careful study of domesticated animals would offer the best chance of making out this obscure problem. Nor I have been disappointed."” To gain clear insight into the means of modification and coadaptation Important conceptsImportant concepts "No species is immutable" "no case is on record of a variable being ceasing to be variable under domestication" Forces of evolutionary change Mutations Gene flow - admixture Genetic drift - allele frequencies change in a small population, "population bottleneck" and "founder effect." Selection local environment, sexual selection, human-mediated "Natural selection has been the main but not exclusive means of modification" How would you define domestication? DOMESTICATION was a major SELECTION event that allowed - humans and their domesticates to spread worldwide and led to dramatic demographic changes - people to manage the genetic diversity of animals, control their evolution to obtain food...
