Mulitregional vs Out of Africa

If there was by chance a parallel evolution, would the bottleneck have occured globally? The evidence for this is in the old world since "they" do not accept the possibility of independent evolution of humans in the Americas.

It's only recently that someone can propose human presence in the Americas prior to Clovis without getting booted out of the room on their butt....as Charlie and Cogs are trying to show.

And frequently with brickbats RW. I would still like to know just how many people were alive before the suggested collapse in population 70 to 80000 yrs ago. If stone age people made it to the Americas after that event could they have not done earlier, and if they did then died out due to climate change many of the pre-clovis objections disappear.

You are developing a talent for understatement.

The Toba event would have created a global bottleneck due to its estimated six year global winter and resulting plunge into severe ice age conditions for a millenium. As I recall, the Yellowstone cauldera blew about 640,000bp and created similar conditions. If the worldwide population was sparse at the time, there wouldn't be much evidence to be found in the first place. Archaeologists at Calico and Hueyatlaco are searching for bones, but in the case of Calico the soil is such that bones do not survive long. However, lacustrine deposits five miles away at Lake Manix show promise.

I believe I picked up an interesting, petrified bone at a site near mine, and I plan to ship it to Charlie for a look. Since it eroded to the surface it will never count as definitive, but I know where I found it and a little digging could pay off after the sites stratigraphy is analyzed. My SWAG is 25,000bp or greater.

Charlie ... you read that? Incoming ...

Well a bone is promising. But a human bone would be a coup d'etat for the preclovis paradigm.

I didn't say that it wasn't a human bone, FM. It looks like a broken human tibia.

Dude!

If you have what you think is a human bone, don't ship it to me, get it to the nearest anthropology dept ASAP. If it is in fact a human bone, they'll be all over it, and you can get you a pro arch team out there.

Got a pic by chance?

Patience, Charlie (why did I say that?). We will speak about this one by PM before it goes further. You'll understand why.

Marduk, this came from a different area. However, I believe you are correct that the ravines on the east side are where bones will be recovered, if at all. It just makes sense.

Don't worry Marduk.
No ones found out your "secret" yet.
