African man with a 339K Y-dna... may have a non-**** sapien origin.

ScienceDirect.com - The American Journal of Human Genetics - An African American Paternal Lineage Adds an Extremely Ancient Root to the Human Y Chromosome Phylogenetic Tree

We report the discovery of an African American Y chromosome that carries the ancestral state of all SNPs that defined the basal portion of the Y chromosome phylogenetic tree. We sequenced ∼240 kb of this chromosome to identify private, derived mutations on this lineage, which we named A00. We then estimated the time to the most recent common ancestor (TMRCA) for the Y tree as 338 thousand years ago (kya) (95% confidence interval = 237–581 kya). Remarkably, this exceeds current estimates of the mtDNA TMRCA, as well as those of the age of the oldest anatomically modern human fossils. The extremely ancient age combined with the rarity of the A00 lineage, which we also find at very low frequency in central Africa, point to the importance of considering more complex models for the origin of Y chromosome diversity. These models include ancient population structure and the possibility of archaic introgression of Y chromosomes into anatomically modern humans. The A00 lineage was discovered in a large database of consumer samples of African Americans and has not been identified in traditional hunter-gatherer populations from sub-Saharan Africa. This underscores how the stochastic nature of the genealogical process can affect inference from a single locus and warrants caution during the interpretation of the geographic location of divergent branches of the Y chromosome phylogenetic tree for the elucidation of human origins.

Amazing! But what does this mean exactly. I know a little about Chromosomes but not enough. Does this mean we have chromosomes that are older than the rest of the race's chromosomes? Explain a little.

y'all gotta know what OP is getting at c'mon man its gundumb


what it means is what we have always known the black man came first and we also know that there is more DNA diversity in Africa than the whole rest of the world so this should come as no shock...


As far as OP is concerned I'm sure y'all will see the purpose of this article soon

now Gundam has a Slayer avatar?

I guess he's going all in with the devil shyt

Horrible explanation/attempt to distort what is actually a fascinating find.

WHY WOULD IT BE SURPRISING THAT HOMO SAPIENS HAVE A NON HOMO SAPIEN ORIGIN, BROTHER? DO YOU THINK EVERYTHING ELSE EVOLVED FROM SINGLE-CELLED ORGANISMS EXCEPT FOR US, DUDE?

Gundam has a lizard's brain, so I don't know why this would be a surprising discovery to him.

the back of his head existed long before the front

this actually isn't that earth-shattering....we've always known that early homo sapiens mated with other human species like the Neaderthals in Europe.....all this guy shows is that the same shyt happened in Africa hundreds of thousands of years ago

I've been a slayer fan for more than 9 years now. I've been to all their concerts when the come to the bay.

I bought an original Vinyl of Hell Awaits.

Homo sapiens arose 339 thousands years ago? If that is so, you can through that traditional OOA theory window.

OOA with total replacement is clearly false now, but saying saying that Homo sapiens arose 339 years ago pretty much discredits the whole theory.
