Advances in human history by following our genetic tree(s)

There are some great discoveries in this field like how much of the DNA have we inherited from these people and how does it vary depending on which regions of the world people are from:

Neanderthals
Denisovans
Floresiensis
Naledi

The better the science is at mapping our genomes and those of ancient peoples the more defined our history is. Turns out we inherited DNA from many different ancient people thought a decade or more ago to have gone extinct when modern humans replaced them.

This stuff fascinates me because there are new discoveries coming at a relatively rapid pace.

This is one of the excellent lectures I've watched recently. Hope some of you will also enjoy it. There are 2 others I'll post in the next few days I think people will like.
