Regarding the multiple human ancestors aspect, here is an diagram of human species or groups if you want to avoid the "what is a species discussion" : https://imgur.com/a/AfrYjqF It is from a recent symposium [1] on human evolution The vertical axis is the age. The horizontal axis represent the geographical spread and the color represents the continent.

We can see multiples things:

- Disregard the 2010, it is indeed up-to-date. These past few years new bars have been added regularly.

- A single homo species is a new development and is an exception and not the rule

- Not only did different species live at the same time they sometimes lived in the same places

- There is no edges between the groups to represent ancestors as a simple "single ancestor" link is not easy to establish.

Wow, that is an amazing chart!

is the poster from, or for* the symposium? If it's the later, it'd not be useful without the resulting discussion.
