I don't have the raw sequence. The project handled DNA data in total privacy. I did send my DNA swab a second time about 5-6 years later, this time to look at my maternal line (mitochondrial dna). The report had changed quite a bit possibly because the project had gathered more data in the intervening years. . I've stopped looking into this further - I really don't care about my ancestors or genetics. More interested…

The field has advanced incredibly since then - uniparental markers like mitochondria or Y are a helpful clue, but we have so much genome wide information now. Indian population genetics is still in its infancy, though, since Indian government rules around the export of biomaterial means only Indian labs can work on them, and honestly most of them have strong biases they're looking to confirm. So much of the Indian po…

He's talking about the fact that Aboriginals, not unlike Native Americans, reject any attempt to explain their origin via science as they stick to the story of their origin that comes from their religion, and see the science based origin as disrespectful.

Got a source for this fact? Generalising opinions to a whole race is rarely wise. Perhaps like anyone else with religious beliefs, those who are offended simply want their culture respected.

For this interested in this topic, highly recommend the book: Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past

More than a decade ago I submitted my DNA to the National Genographic Project [1] which was an attempt to trace ancient human migration using Y chromosome and mitochondrial DNA from a sampling of people around the world. My paternal Y-chromosome line showed an ancient mutation (>50K year ago) carried by humans who had likely spread through a coastal migration from Africa around coasts of the Arabian Sea down to South…

These charts don't show what you apparently think they do. The samples in the larger datasets (like the HGDP) are chosen for their differentiation, often from indigenous groups, with admixture samples usually removed (the first adds in a few admixture types for the specifics of their study).

It's an emotionally charged subject, which is unfortunate as it's objectively fascinating from a purely historical perspective. The simplified and (generally) commonly accepted narrative is that a cohesive group arrived here 45-60,000YA, lived peacefully and in harmony with the land right up until Europeans arrived. There's some debate about the megafauna extinctions, but no conclusive evidence either way. (I did app…

It’s my understanding that while Harari’s books are fascinating and entertaining reads they’re mostly pop-science and lack much actual science. He’s a good storyteller but he presents his stories as though they’re fact when they are, at best, conjecture.

I got a few pages into Sapiens before thinking the same thing. I prefer a few rigorous ideas to a thousand flimsy ones.

The only interesting thing I know about Aborigines is they're the only known people who didn't invent the bow and arrow. As a hobbyist archer this is fascinating to me. They apparently didn't need it, as they're still around.

They're also the only culture to invent the boomerang which is a weapon that comes back to the thrower. Pretty cool if you ask me

Not really. https://en.m.wikipedia.org/wiki/Boomerang

  Although traditionally thought of as Australian, boomerangs have been found also in ancient Europe, Egypt, and North America. There is evidence of the use of non-returning boomerangs by the Native Americans of California and Arizona, and inhabitants of South India for killing birds and rabbits.

No, they do not all do this, and I'd caution you on speaking for a people that aren't a monolith within their mobs in the first place.

Even more so, in this case, considering my country's historical "handling" of ATSI culture, and the mobs in general.

Hunting boomerangs didn't return to the thrower. Picture a symmetrical returning boomerang you're used to, now massively shorten one of the "legs": that's the hunting boomerang I've been shown

Aha I thought about replying to the parent comment.
