Animal species such as dogs, pigs, cattle, chickens, and horses havebeen considerably changed in both phenotype and genotype over the past 15,000 years. They have beensubjected to novel selection pressure and have evolved genetic adaptations to the human niche. Arelaxation of selection when animals left the wild environment and positive selection due to intentionaland unintentional human preference can both lead to domestication traits. Identifying potential selectiontargets during and after domestication can provide new insights into the genetic basis underlyingdomestic traits and general mechanisms by which genetic variation shapes phenotypic diversity.Meanwhile, with recent advances in ancient DNA techniques, it is feasible to derive both the time and theintensity of selection.In this project, we aim to infer signatures of selection from population genomic data of both contemporaryand ancient samples for several domestic species such as chickens, dogs, and cattle. We also intend todiscern genes under selection during the domestication from genes affected by recent selectiveprocesses. Supervisor: Dr Matteo Fumagalli Research
