Genetic history of dog domestication
PNAS Science Sessions
Genetic tests don't reliably predict behavior
Katia Bougiouri and Kathryn Lord emphasize behavior's polygenic nature and environment; Lord reports tests fail to predict behaviors accurately.
Genetic history of dog domestication
Science Sessions are brief conversations with cutting-edge researchers, National Academy members, and policymakers as they discuss topics relevant to today's scientific community. Learn the behind-the-scenes story of work published in the Proceedings of the National Academy of Sciences (PNAS), plus a broad range of scientific news about discoveries that affect the world around us.
In this episode, researchers explore the impact of domestication on dog genetics and behavior.
In this episode, we cover: •[00:00] Introduction •[01:00] Greger Larson explains how the history of gene flow between dogs and their wild relatives differs from what we know about other domestic species. •[02:38] Audrey Lin finds that low levels of wolf ancestry are found in almost two thirds of dog breeds. •[04:18] Linus Girdland Flink documents evidence of two genetic wolves on a remote Scandinavian island that may have been under human control. •[06:13] Clément Car explores how the mating systems of free-ranging village dogs could provide insight into canine domestication •[07:43] Katia Bougiouri explains how she used a statistical method to improve ancient genomes and what her results reveal about the history of inbreeding in dogs. •[09:21] Lachie Scarsbrook explains how he used museum specimens to reconstruct the history of inbreeding in German Shepherd Dogs. •[11:10] Eleanor Raffan analyzes genetic data and owner-submitted behavioral questionaries from 1,343 golden retrievers. •[12:54] Kathryn Lord finds that genetic testing cannot accurately predict canine behaviors. •[14:25] Final thoughts and conclusion.
