Re: definition?
Hi, Coyote.

I have to say, even as a skeptic of multiregionalism, there is a lot more admixture than I would have expected. And the earlier dates in this new study do show a lot more complexity to the history of human evolution. It's certainly a wide-open question as to how much intermixing there actually was.

Just how far do we think this evidence can go? For example, is it possible that modern Asians are best explained as surviving Homo erectus, with some Homo sapiens admixture?

Re: definition?
Not sure if it can go that far, but the original multi-region hypothesis I learned in grad school a while back noted the commonality of traits from early erectus to late erectus in each of four areas of the world, with influence from those to modern populations. Shovel-shaped incisors was one example of Asian traits carried into modern populations.

But genetics will be adding a lot more clues, so stay tuned!

braided net
The big news from recent finds is the date and nature of the out-of-Africa movement for modern humans is being refined, and the multi-regional hypothesis is being reexamined.

In other words both are right and both are incorrect ... or not completely correct.

So, what we have with interbreeding is a braided or interwoven net, that all came out of Africa and then shared traits developed after leaving Africa, rather than spontaneously arising in different independent populations (which has always been where my skepticism of the multi-regional hypothesis).

Enjoy

And this all occurred earlier than has been commonly assumed under the traditional out-of-Africa hypothesis.

not just earlier
It seems it was not just earlier but also relatively repetitive; think "Spring Break". When there was a chance to party, people partied; again and again and with "targets of opportunity".

Anyone so limited that they can only spell a word one way is severely handicapped!

Re: not just earlier
Right. That chart in Post 8 almost certainly under-represents the amount of hanky-panky going on.

I think you have the Multitegional Hypothesis confused with something else.

Re: braided net
Perhaps you could elucidate what you think the multi-regional hypothesis says. I will admit that I never gave it much credence because of (my) perceived obstacles for developing similar characteristics in different places or some kind of emergence from a chrysalis in different places.

A pattern of interwoven or braided genealogies however does provide paths for sharing different traits across many areas creating a montage of mosaic patterns.

Enjoy

And that's exactly what MH is:

quote:
Wikipedia on Multiregional Origin of Modern Humans (emphasis added):

Multiregional evolution holds that the human species first arose around two million years ago and subsequent human evolution has been within a single, continuous human species.


This thing you're talking about involving independent evolution of identical characteristics in unconnected populations isn't MH.

New fossil announcement
http://www.mirror.co.uk/...s-new-dwarf-human-species-7566527

Posting here for lack of a better spot:

Mysterious new dwarf human species probed after scientists find 3 million year old skull in cave

A multi-disciplinary team of scientists have discovered the skull of a weird, unique extinct human and who was found in an underground cave.

Scientists have discovered a skull belonging to a previously unknown species of human from three million years ago.

The research team made up of paleoanthropologists stumbled across the remains in an underground cave and have now put together a skeleton which stands at 4ft 9 tall and is described as "a really, really strange creature."

Lee Berger of the University of the Witwatersrand in Johannesburg and his co-horts stumbled across 15 individuals skeletons which they believe make up a tribe of the bizarre human species - and now they've found the missing link.

And while they resemble homo sapiens - like modern day humans - the species could more more than 2.8 million years old.

More

With all of these finds lately, and the addition of DNA evidence going back hundreds of thousands of years, things are getting interesting!
