Inuit sled dogs have changed little since people migrated with them to the North American Arctic across the Bering Strait from Siberia, according to UC Davis researchers and colleagues who have examined DNA from the dogs from that time span. The legacy of these Inuit dogs survives today in Arctic sled dogs, making them one of the last remaining descendant populations of indigenous, pre-European dog lineages in the Americas.
Students from any major on campus can engage in undergraduate research in the UC Davis College of Letters and Science. As a senior, Cole Williams pursued his interests in genetics with a project in the lab of Brenna Henn, associate professor of anthropology. Williams, a genetics and genomics major in the College of Biological Sciences, designed an algorithm capable of handling diverse population and complex family genealogies in human genomic datasets.
Study finds that a gene for lighter skin spread rapidly among people in southern Africa in the last 2,000 years. University of California, Davis, researchers and colleagues report that the gene was introduced from eastern Africa to southern African populations. Strong positive selection caused this gene to rise in frequency among some KhoeSan populations.
