Random info for you nostr:npub1sg6plzptd64u62a878hep2kev88swjh3tw00gjsfl8f237lmu63q0uf63m, the world's oldest known footwear to mankind (~8000 years old) is a pair of sandals found in a cave in Missouri, US - made out of leather and woven fiber (from a plant that is an antidote to snake venom) likely created by American Indian tribes.

8,000 years is perhaps half way back to the migration of humans from Asia across the Bering land bridge into North America. That migration took place at the height of the last glaciation when ice sheets a mile thick sprawled over lattitudes as far south as Michigan and Wisconsin, where I am currently typing this. That glaciation ended ~12,000 years ago. So those sandals were as far removed from the ice as we are from the building of the pyramids.

BTW, that glaciation was just one of about fifteen that have engulfed the Earth in the past 1.5 million years. Each lasts about 100,000 years, and each has been interrupted by about 10,000 years of relative warmth. The next one is not quite overdue.

Wow that’s a great piece of history, uncle Bob. Thank you for putting it to perspective.

This was studied by an archeologist from the University of Missouri - and possibly the shoes it survived because of the caves dry and consistent environment.

I find the history of human migration incredibly fascinating. I’ve read some of Adam Rutherford’s books on it but I def don’t know enough. Were glaciations highly related to fault lines back then ?

Pam, Yeah, the history of migration is pretty interesting. I don't know if there is a correlation between glaciers and fault lines.

Thanks for the Rutherford reference. I just ordered "A Brief History of Everyone who Ever Lived".

I see by that reference that you have studied the "Out of Africa" hypothesis based on mitochondrial and Y chromosome DNA. I find that _really_ interesting. It shows the trek of humans out of East Africa ~200,000 years ago; and how the whole species nearly got wiped out by the explosion of Mt Toba 70,000 years ago. There may have been as few as 100 homo-sapiens who survived that event. That's one of the reasons for our current genetic homogeneity.
