Wrt origins of modern humans.
Oi! What a rabbit hole!

I wrote, modern humans had been around for 300ky and came from Southern Africa. But it turns out, this history is 1) wrong (sorry!😁 ) and 2) not written in stone yet, at all. #Archeology is still developing an agreement of what distinguishes modern humans culturally from their archaic ancestors for one thing, and the other thing is, 50+ years-old excavation sites still reveal unthought-of new twists.

Eg. in 2016, Mirazone-Lahr and Foley on "Human Eevolution in Eastern Africa" https://www.researchgate.net/profile/Marta-Mirazon-Lahr/publication/301232255_Human_Evolution_in_Late_Quaternary_Eastern_Africa/links/59e33487aca2724cbfe36a63/Human-Evolution-in-Late-Quaternary-Eastern-Africa.pdf ( https://link.springer.com/chapter/10.1007/978-94-017-7520-5_12 )

published this handy chart below. X-axis is in kiloyears since 800ky. Above the x-axis are the ice ages and interglacials in form of the well-known temperature curve. Left y-axis splits the continent into North, East and South Africa; the right y-axis lists names of archeological sites of the finds.
The coloured dashes within the chart area highlight where remains have been found, and when they lived, and to which homo kind they belonged, Anatomically Modern Humans (red), H. #heidelbergensis (blue), and an advanced form of H. heidelbergensis with larger brain sizes sometimes known as H. #helmei (green).

Very handy chart. From 2016.
But...!
