Fossilized feces found in Oregon suggest earliest human presence in North America

They found so few coprolites in that cave, I bet they were just passing through.

I was under the impression that A2 and B2 were subgroups of the Asian sourced haplogroups A and B and exclusive to the Americas.

This is one of the most recent maps I have seen, from last fall. It is from Beringian Standstill and Spread of Native American Founders:

Thanks I've read one of those and I just looked at the other, if they're the best at the moment then this should read “haplogroups A2 and B2, haplogroups common in Native Americans rare to nonexistent in Siberia and east Asia.”

Re “More here:”

This site has 4 or 5 other articles of interest to people at this thread, on death of megafauna, 50,000 remains in US, Neanderthal revised studies, etc.

You must really dislike science.

Looks like the “American Indians” are going to lose their rights!!! /sarc

That would be just offal.

“That would be just ‘offal’.”

Nice pun!

[SunkenCiv]

It’s stool late to tell now.

They were glad for that collapse layer, because it capped the older strata. The dig was meticulous, and funded year after year, pretty much a dream situation for the excavators. Adovasio was so tired of having the same tired worn-out fake counterarguments trotted out, that (by his own account) he exclaimed “horse —” at what was supposed to have been one of those peer-to-peer roundtables on the finds.

we know something about what they were eating, which is something we can learn from coprolites. We're talking about human signature.

I guess that sounds more refined than "dropping the kids off at the pool."

[wildbill]

we’ll just have to like it or lump it.

[SunkenCiv]

This new data really does bowel me over.

...if they're the best at the moment then this should read “haplogroups A2 and B2, haplogroups common in Native Americans rare to nonexistent in Siberia and east Asia.”

I'm not sure I follow. Would you mind putting a little finer point on your statement so this ol' East Texas country boy doesn't have to guess at what you mean???

[gleeaikin]

“THey were glad for that collapse layer, because it capped the older strata.”

But do you know if they have dug into the older strata, or do they have plans to do so, and do they have any idea what caused the collapse?

You can still do that in New York City. I saw it once. Was a “lady” even! Crowded sidewalk and everything - unbelievable!

Isn't that special.

This is how I'm currently reading this. The mtDNA haplogroups that are common among nearly all Native Americans (north and south) are A2, B2, C1 and D1.
A2 and B2 descend from haplogroups A and B which are Asian. From what I've read, A2 and B2 are considered to have originated in the late Pleistocene in the earliest founder population of the Americas.

Since these haplogroups are common throughout the Americas (and found in ancient DNA samples in the Americas) and rare in Asia (and not found in ancient Asian DNA samples) it seems to be accepted that any occurrence of A2 or B2 elsewhere is the result of gene flow out of the Americas to other places.
