Ancient DNA Analyses of Domestication

A transformative step in human evolution was the domestication of animals and plants. Domestication has resulted in large phenotypic changes resulting in the creation of new species, such as the origin of the domestic dogs from their wolf progenitors, between 20-40,000 years ago, and maize from teosinte, approximately 10,000 years ago. However, domestication can also result in relatively few genetic and phenotypic changes. For example, evidence suggests that cats have changed little in the approximately 9,000 years since they deigned to become a companion to humans. Recent advances in sequencing technology have allowed us to sample ancient remains and better understand the genetic changes and processes that underlie domestication. Beyond the identification of selection for traits of interest and the origins and fates of domestic species, this line of inquiry teaches us about the progress and aims of our ancestors. In this special series we present research examining how ancient DNA studies informs upon animal domestication.
