What are Homo sapiens?

A 15-minute history of 6 million years of evolution, by Sarah Wild at Live Science

In the last 15 years, the number of Homo species has more than doubled from four to nine. The most recent addition was H. luzonensis, in a paper published in 2019.

An Ethiopian H. sapiens fossil is 195,000 years old, while archeological evidence suggests that modern humans may have appeared 315,000 years ago.

By comparison, all of civilization is a mere 12,000 years old.

This article includes a photo of the Cave of Hands in Patagonia, which is is amazing. It is humbling to consider that we’re looking at the handprints of our 10,000-year-ago ancestors.
