Rules:

Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Ancient genes pinpoint when humans and Neanderthals mixed and mingled (apnews.com)

Summary

New research suggests humans and Neanderthals interbred around 45,000 years ago, refining earlier estimates.

Genetic analysis of ancient human remains from the Czech Republic and Germany revealed Neanderthal DNA, aiding in pinpointing the timeline.

A separate study highlights how Neanderthal genes related to immunity and metabolism helped early humans adapt outside Africa.

Modern humans still carry Neanderthal genetic traits, influencing skin color, hair color, and nose shape. Future studies aim to further unravel humanity’s genetic history and connections to extinct relatives like Denisovans.

This summer, it was discovered that there is a possible link to our inheriting Neanderthal genes and autism. Not everyone has the same genes that humans got from Neanderthals, but certain Neanderthal genes seem to be more common in people with autism.

That actually fits in my view of things. Neanderthals were obsessive engineers. They were not much on innovation when it came to tools, but they focused so much on perfecting the tools they did innovate that having certain autistic traits like an obsessive focus on specific tasks is pretty useful. Homo Sapiens were definitely better innovators, but Neanderthal tools were so perfectly engineered that only the most expert of flint knappers can replicate their expert functionality.

I know stone tools look simple, but they absolutely are not.

We also know from that other study this summer that two groups of Neanderthals stayed in their respective cave system 10 days away from each other, for 50 000 years, and never interbred. People from the end of that 50 000 year period had the same gene pool as those from the beginning, and none from the neighbour group. 50 000 years of no one walking 10 days to clap cheeks. Until the extravert Sapiens jocks walked in and adopted an introvert Neanderthal to pull out of their cave and fuck for, apparently, some 5 000+ years, shortly before Neanderthal extinction (or assimilation of the hot ones into Sapiens I should say).

That article pondered the difference in world views between the two, but yeah, autism works too.

Why the hot ones only? Having a warrior brute around sounds sensible too. Or just a refugee family of neanderthals who's children interbred with the sapiens after a generation.

I think violence is a very valid theory in the process of interbreading, given how humans tend to be a violent species. But the fact that children resulted out of that interbreeding that were aloud to interbreed themselves speakers for at least some level of peacefully integration.

At least as peaceful as slavery as it was practiced in the United States.

[–] [email protected] 1 points 3 days ago

That is of course possible and ultimately we will never know.

I don't have hard data on this, but if interbreeding between slaves / sex-slaves and whites would have been widespread I think there would be a lot more interracial people in the US. As it is the black and white ethnicities remain still notably separated, with laws up into the 1960 making it a crime to have partner that is not one's own race.

And yes, 1865 to now is a vastly smaller time frame than 45.000 years, and if we make it that long one the picture would be a different one.

Now I feel like such a homo. I feel totally opposite of what you describe. I can go down rabbit holes but im just such a horrible doer.

It was a Tuesday night when Throg took Six Feathers as a prisoner during a raid on the human camp.

I'm tired and read this headline as humans and the Netherlands.
