Archaeologists Use Tooth Enamel Protein to Show Sex of Human Remains

July 17, 2020
A new method for estimating the biological sex of human remains based on reading protein sequences rather than DNA has been used to study an archaeological site in Northern California. The protein-based technique developed at the University of California, Davis, gave superior results to DNA analysis in studying 55 sets of human remains between 300 and 2,300 years old.

Unique Sled Dogs Helped the Inuit Thrive in the North American Arctic

December 04, 2019
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.

Study Challenges Role of Speech Gene in Evolution of Human Language

August 03, 2018
The FOXP2 gene has been associated with uniquely human language abilities. But a UC Davis scientist and colleagues did a study with a wider variety of people and found no evidence of selection for FOXP2 in modern humans, challenging previous of how we think humans acquired language.
