7k-year-old skeletons from the green Sahara reveal a mysterious human lineage
- begueradj 2y ago> "despite practicing animal husbandry—a cultural innovation that originated outside Africa" Animal husbandry was a response to unproductive hunting. And since desertification - hence unproductive hunting- started long time ago in Africa, it makes sense that animal husbandry started there too before it appeared elsewhere.
- dani__german 2y agoit is one logical pathway, but another is to simply move to a new area, rather than develop animal husbandry. Which one seems more likely?
- HelloNurse 2y agoBoth at the same time. If you repeatedly migrate in order to maintain a foraging and hunting lifestyle, you are sufficiently aware of the undependability of foraging and hunting to make large R&D investments in experimental methods of agriculture and animal husbandry.
- psunavy03 2y agoDepends on how many science points and settlers you have, and where you are on the rest of the tech tree.
- detourdog 2y agoI think the development cordage(rope) and woodworking techniques would have a heavy influence on slowing down, noticing the surrounding abundance. Once a location becomes favorable more substantial and long lasting structures could be made. My question is what was the divide that kept these groups at 50kyo. Something kept them apart. I hope they get samples from different beings to analyze.

- Tuna-Fish 2y agoAnimal husbandry did not start in Africa, though. It started in the fertile crescent and spread into Africa. This is very well attested in archaeological finds, and in the fact that the relevant animals were domesticated first there. The surprising news is that the spread of animal husbandry didn't seem to accompany the spread of human genes -- the subsistence strategy was adopted by learning, not by people moving. I don't think this is very shocking because the same thing seems to have happened elsewhere. While agriculture mostly spread by people moving, the culture that developed into all the pastoral cultures of the Eurasian steppe seem to have been hunter-gatherers living in close proximity to farmers.
- MichaelZuo 2y agoBut how does that prove there was no animal husbandry in Africa in the prior hundreds of thousands of years?
- jjk7 2y agoBecause there's no evidence of it until after it was developed outside of Africa? You don't have to prove something that doesn't exist. Find the evidence, and prove it does.
- Tuna-Fish 2y agoAnimal husbandry leaves behind a lot of evidence, starting from different distributions of animal ages and sexes found in bones in refuse pits, to genetic evidence of artificial selection. This evidence is found everywhere. But it's dateable, and you can find the oldest instances of it in the fertile crescent.
- MichaelZuo 2y agoDo you really need me to remind you that absence of evidence is not evidence of absence?

- mannyv 2y agoWhat's interesting is that the population remained isolated for tens of thousands of years. Generally speaking, people move around and are promiscuous. Staying isolated for that long implies a physical barrier, because cultures generally don't survive for 40,000 years. But an isolated population means genetic issues - but if the population is big then they should have spread at least somewhat.
- vfclists 2y agoWhat exactly is "mysterious" about it? Click-baity title?
- owlninja 2y agoCurious how this post says '5 Hours ago' but if you search or click 'smithsonianmag.com' up there, you see this as a post that says 3 days ago?
- macintux 2y agoThe moderators keep an eye out for interesting content that is ignored on submission, and put the posts back into a queue to be published again.
- owlninja 2y agoThanks to both of you!
- marcellus23 2y agoThe admins do this sometimes, it's called the "second-chance pool" or something like that. They'll look at stories from the past few days that deserved more attention than they got, and essentially re-submit them.
- voxleone 2y agoPlease accept my critique to Smithsonian Mag made in good faith: never use the word 'mysterious' [a nod to the magical thinking] in a science context. Really looks like CNN-ish dark pattern. The URL slug has a better word choice: 7000-year-old-skeletons-from-the-green-sahara-reveal-a-previously-unknown-human-lineage-
- neaden 2y agoI don't see the connection between mysterious and magical thinking. It just means it is a mystery and I don't see anything that implies magic about a mystery.
- PaulRobinson 2y agomysterious: adj. difficult or impossible to understand, explain, or identify. While magic requires mystery, mystery does not require magic and they are not synonyms. It is perfectly valid to state something is a scientific mystery without implying magic is involved in some way.
- ziddoap 2y agoWould you be able to explain the mystery = magic thinking connection? I've not heard it before. I've obviously heard magic being described as mysterious, but not that mysterious stuff implies magic.
- Carrok 2y agoThe skeletons are mysterious and important.

- Vaslo 2y agoI’ve been enjoying a podcast called Our Prehistory. If you are interested in this kind of stuff, the first few episodes get really into this, and it’s definitely sunk some misconceptions I had about evolution (that other species groups lived among the Homo Sapiens), why they died out, more branches than originally thought etc.
