Evolution of the Human Brain

The video explores the study of ancient DNA to understand the evolution of organisms. It introduces Peter Holland, a zoologist at Oxford University, who guides the discovery of amphioxus, a marine creature with genetic links to humans. The video compares the anatomy of amphioxus and human brains, highlighting genetic similarities that reveal insights into brain evolution over 500 million years.
