The Quagga Project is one in South Africa that was started by conservationist Reinhold Rau who suspected from their skins and skeletons that the extinct Quagga was a subspecies of the Plains Zebra. Later DNA examination would confirm that identification. So, since 1987, volunteers and ranchers have been selectively breeding Southern Plains Zebras to create individuals that resemble the lost Quagga in appearance. The process is quite far along, and there are now the new Quaggas, ofttimes called Rau Quaggas after the conservationist who started the process, that have brown hindquarters nearly devoid of stripes like the original Quaggas.

I always find it fascinating that archeosamples will have enough shared information to decide that I am descended from the same sample (or at least share a source) but, the closest modern match for the sample is a place that is not at all included in my family history.
Daniel, so much good info. Watched to the end. But you need to slow down, everyone is here to listen to you cause you the boss. Also Mr Crawford should jump in there once in a while lol.
I read somewhere that anyone with English or maybe British ancestry could claim descent from Edward III or anyone alive in England/Britain then or earlier, same with anyone with European ancestry from Charlemagne or anyone alive then or earlier (in Europe). As you say. It’s called the ‘genetic isopoint’.
Great discussion. Just to put in a comment on randomness, it's a mathematical concept used to model circumstances where cause and effect are too complex to observe or describe (or are unknown). Actual randomness doesn't happen in the tangible world, because the result would be an effect that is not attributable to a cause. This is not intended to criticize the work described in this presentation, because it's mathematical work.
75 percent is definitely a good speed. Great content, but totally his brain is running at a faster speed than mine. Appreciate the knowledge and the varied expertise recently.
Y-chromosome replacement by the Yamnaya intrusion into Europe seems shockingly abrupt and violent. Forget about paying these bands of Yamnaya herders tribute like the sedentary farmers would wrt to nomads like the Scythians, Alans and the Mongols later on. Seems that business model hadn't been invented back then so it's just a very brutal straight up near total replacement. 🤔
To @bjarnitryggvason7866 It could be a question of, "Do you want some of their wealth in the form of tribute, or do you want their lands and their women?"
Interestingly enough there are no mass graves found in Asia (Iran and Indian subcontinent) like in Europe. Indo-European expansion into Europe was brutal.
How does a gradual replacement model fit in with the evidence? For example the incomers having a social or economic advantage that leads to more successful children, and, over a few generations, has a large impact on the genetics of a population? You say they weren’t intermarrying, what’s the evidence for that? Lack of native European mitochondrial haplogroups vs Y? Does it appear whole families moved in? Could it have been that they did intermix but those who did, and those who were native to the region, were less successful over a few generations? Thank you so much. Very interesting topic. Probably will watch multiple times.
Sounds like nervousness to me. Nervousness combined with being excited to talk about what interests you, combined with trying to not slide into jargon. Not as relaxing to listen to as Jackson's voice, but interesting still. And feels like he gets more comfortable along the way.
1:15:00 I think the data is not showing CW are descendants of Yamanaya particularly because the Y haplogroup of Yamanaya is R1b-L23 and that of CW is R1b-269 which are “cousins”.
Chimps are not ancestral to humans. Humans and chimps have a common ancestor, Where there's a variation in the genome between the two (humans and chimps), you can't determine which version is ancestral without other information.
It's the first time I've felt I had to slow down the playback... Fast talker, that man 🤣

Lecturing tips for Daniel: slow down, stop apologizing, don't hedge so much. You do have authority to speak.
It's something many of us struggle with, but with enough practice/confidence can be overcome!
Hedging is important. It’s unhelpful to convey false certainty.

You should try and get Razib Khan on to talk genetics, he is brilliant.

under-determined =/= in-determinate v un-determinable, it is all higher level stuff which can be unpacked

Ossified means bony. Fossilized means replaced by minerals.

CWC brothers to Yamnaya, or possibly decendants. Guess we soon will know.
Interesting. But please cut back the "ahs", the "likes", the "kind ofs", etc. Clear articulation also helps.

So hard to watch for a non native English speaker, this speed is unintelligible
Maybe you need different technology if you're farming more & herding less, or if you're more sedentary and less nomadic. Re Corded Ware people.

/jámnaja/, not /jamnája/.
Steppe is probably better than Yamnaya as their Y-DNA doesn't match most European men, despite being genetically similar.
