Denisovans or Homo Sapiens: Who Were the First to Settle (Permanently) on the Tibetan Plateau?

The Tibetan Plateau has long been considered one of the last places to be populated by people in their migration around the globe. A new paper by archaeologists at UC Davis highlights that our extinct cousins, the Denisovans, reached the “roof of the world” about 160,000 years ago — 120,000 years earlier than previous estimates for our species — and even contributed to our adaptation to high altitude.

Asked and Answered: Why Haven’t All Primates Evolved Into Humans?

Many people mistakenly think of evolution as progress. But humans, despite their ability to manipulate objects and change their environment, are not “on top” of the world’s species. Research by Lynn Isbell, chair of the UC Davis Department of Anthropology, suggests that ancestral humans and other primates developed different strategies to find food and avoid predators.

Rewriting the History of Our Species

New fossil finds from the Jebel Irhoud archaeological site in Morocco do more than push back the origins of our species by 100,000 years. They also reveal what was on the menu for our oldest-known Homo sapiens ancestors 300,000 years ago

On Early Human Migration, Geography and Culture

UC Davis anthropologist Alexander Harcourt sums up the latest research on early human migration around the planet, saying that Homo sapiens left Africa earlier than previously thought and our diverse cultures have been heavily influenced by geography.
