Where did they all go? How Homo sapiens became the last human species left

There are many theories around the disappear one e of our human cousins, and limited evidence to decipher exactly what happened.

Some of the other species are only known by a handful of individuals.

In Africa, there are surprisingly few fossils of Africa apiens first emerged, where there is surp Prof Chris Stringer nderthals roamed Eurasia un the Natural History Museum , li London n small groups and interbreeding.

H sapiens had larger groups and greater genetic diversity.

This allowed for the exchange of ideas and innovation, says Stringer.

Some people currently living in Eurasia have up to 2% Neanderthal DNA.

In fact, some geneticists about 40,000 years ago ssemble about 40% of the Neanderthal genome from the living sequences.

An unknown human ancestor contributed between 2% and 19% of their genetic ancestry to people living in west Africa today.
