Landmark ancient-genome study shows surprise acceleration of human evolution

Is there any species, other than humans, that is found all across the globe (i.e. geographically separated), and has not differentiated into subspecies? Wolves, elephants, tigers, bears, and foxes have all been categorized into multiple subspecies each, distinct but able to interbreed.

Every time I read about ancient DNA work, it's about Reich's research. Can anyone expert in the field shed light on that? He certainly seems to have a successful research group. And he's a good communicator, I got a lot out of his 2018 book. Who else should I be reading or reading about?

Not that surprising when you consider, as the paper does, the explosion of very meaningful traits such as the ability to digest lactose and various anti-malaria adaptations e.g. Sickle Cell and the Duffy-null mutation.

It's just controversial for obvious reasons. The notion that human groups may have meaningfully evolved in different ways over the past 10,000 years, and may still be evolving, is an unpopular one on both ends of the political spectrum.

funny how racists on twitter havent learnt that skin color is a function of natural selection, how do we get this message to them in a non offensive yet informational enough way to change their perceptions of colored people

"To supercharge the search, Reich, Ali Akbari, a computational geneticist at Harvard Medical School, and their colleagues amassed the largest-ever collection of genomic data from ancient humans — from a total of 15,836 individuals from western Eurasia — including more than 10,000 newly sequenced genomes."

Without commenting on the content of this sentence or article, I will say that it is refreshing to see sentences like this in the wild after being regularly and constantly subjected to LLM slop.
