@HalfwayToHobo @joshtpm It's like they think she fell out of a coconut tree

@rgoodlaw PA doesn't really have an AG right now. There's a party-switching benchwarmer in as a placeholder, but they're not in a position to make waves.

@LeMoustier @AdamRutherford @theAliceRoberts And worth pointing out that it's not mere "survival". There are orders of magnitude more Neanderthal gene-copies walking around today than there ever were when Neanderthals were alive. There's a non-trivial manner in which Neanderthals are currently leading their best lives!

[drplatt @drplatt]

@LeMoustier @AdamRutherford @theAliceRoberts Exactly! It makes the word "extinct" a rather slippery one.

[drplatt @drplatt]

@theAliceRoberts @LeMoustier @AdamRutherford Well put. I agree, this is a bit of positive evidence towards no Neanderthals in Africa and a new avenue of investigation into a period of human history with a weak fossil record.

@GenomeNathan @kareem_carr @lpachter If I'm reading you right, Chi-squared/Fisher's exact tests achieve what you're asking: test if each subset has a common success rate.

[drplatt @drplatt]

@Carboniferoys @owengwynne59 @AdamRutherford Right. We know it wasn't exclusively one direction or the other. We're still trying to figure out what the relative contribution of makers and females was, but I don't think we're close to an answer yet.

@mclo_Bridger @apragsdale H. sapiens seems to have originated in Africa ~300kya. Fossil evidence puts early examples in Eurasia ~100-150kya. This paper identified sapiens genomes in Eurasia ~250kya.

@hhawk @SarahTishkoff Claude was thorough and hit pretty much all of the main themes, but got about half of them fundamentally wrong.

[drplatt @drplatt]

@mathiesoniain @AdamRutherford Iain is right, and I think it's worth being explicit here that the interbreeding that gave us our Neanderthal ancestry is a different event that happened much more recently (~50kya).

[drplatt @drplatt]

@LeMoustier @AdamRutherford @Boothicus Yes. That mitochondria observation was a real eye-opener.

@colinrtalbot @AdamRutherford The University scientific support staff wrote us this nice press release: https://t.co/hyLIx6d5Hf

[drplatt @drplatt]

@AdamRutherford We don't see Neanderthal ancestry in African populations that didn't come in with non-African modern human ancestry. Instead, we think this early anatomically modern human group left Africa and encountered Neanderthals somewhere in Eurasia.

[drplatt @drplatt]

@ibis153 @AdamRutherford It suggests there were multiple migrations of humans out of Africa, with the early ones largely ending in extinction.
