Meet Dragon Man, Humans’ Possible New Relative | SciShow News

The video discusses the discovery of Dragon Man, a cranium found in China, which may represent a new human species, Homo longi. This species could be more closely related to modern humans than Neanderthals. The video also covers the earliest known case of plague, found in a 5000-year-old skeleton in Latvia, revealing insights into the evolution of Yersinia pestis. The findings suggest that the human evolutionary tree and the history of infectious diseases are more complex than previously thought.
