Reading stories about ancient hominins always piques my imagination. The incredible spans of time, the various species and subspecies (of which at least some were apparently interbreeding), and the lack of historical record always leave me wondering what endless stories have been lost to the annals of time.
And how (and why) did they manage to populate so much of the planet so long ago without any technology. What made them venture out more and more over thousands of years to end up in the Americas, Asia, Oceania, etc. On foot!
Chris Hasler is the wonderful person that made https://historyoftheworldpodcast.com which is a great resource for anyone interested in the topic. Especially the early episodes in Volume 1.
