What Drove Homo Erectus Out of Africa? (2021)
- j_koreth 5y agoOne mechanism that wasn't described in the article and for fairness I know little about when it comes to prehistoric hominids is the role of community splits forcing certain members to go out or die trying to establish hegemony.
- ttyprintk 5y agoI wouldn’t expect them to study that. This article is about second-order change in population density coinciding with the rate of environmental change.
- WalterBright 5y agoI wouldn't be surprised if it was simple curiosity.
- rackjack 5y agoArmchair answer: many things, probably including Homo Erectus itself.
- esarbe 5y agoIntra-species competition would also have been my first guess. Homo erectus seems to have been quite a successful species, given the archeological evidence. And given the time frame of the migration, I'm betting on a slow but steady expansion as the families and tribes grew larger and split to explore new territories.
- jimmytucson 5y agoIt’s funny, as someone with a child’s understanding of cavemen, I sneer when I read the question. “Isn’t it possible,” I think, “that as nomads, they simply wandered up out of there by accident?” I think any article on this topic should start with why that’s not possible, for the benefit of other children and cavemen like me!
- watwut 5y agoNomads did not traveled for the fun of it. They moved either because of business - buys stuff here, move over there and sell them. Or because of environment - the sheep have better environment here in summer and over there in winter. And places where we could stay all the time are already taken and they guard them, so we have to move. When nomads find a place where they can settle stably, they overtime tend to stay.
- esarbe 5y agoWere they nomads? I'm not sure that there is too much evidence for that, is there?
- lionkor 5y agoJudging by last summer I spent in southern Russia, probably the deathly heat and lack of chilly summer mornings
- WelcomeShorty 5y agoTL;DR Environmental changes, maybe.
- JoeAltmaier 5y agoIf Homo Erectus had any similarity at all to us, then some young blood decided one summer to take a walkabout, for no reason.
