Indeed. I wonder how long it took to develop distinctive racial characteristics? That's got to take awhile...

I think skin color would be fast. Like 10K years. But bone structure, lung size, etc, etc could have been just as fast. The South American's living in the mountains all have barrel chest to breath in enough of that thin air.

It may have been that human evolution was branched and not lineal, so different looks and shapes etc. could have been occurring in different places as a result of isolated populations and environmental adaptation factors, possibly even interspecies interbreeding with other hominids / humanoids.

Not to mention...alien intervention.

Here is a thought.
Bridges work both ways.
Sure it wasn't the Australian Aboriginal (oldest surviving culture) that populated the rest of the world?
It's pretty cool that you guys have marsupials and somehow a duck fucked a beaver and you got a Platypus...but no...humans did not originate in Australia. I'm sorry.

The earth was much warmer then, so everywhere had less ocean between them than today. It does appear that the AA got to South America well before the American Indians came over from Japan. Maybe as early as 50K years ago.

You could ride the equator to Africa, then down and around and on across. That's two pretty short passages navigating with a coconut shell with a hole in the bottom.

Im not saying we did. But land bridges work both ways. Some people are questioning the accepted Africa theory and Australia has been mentioned.

But either way they would have to find the DNA link.
"There are 11 more entries in this list of non-starters, all missing from both Europeoids and “all non-African groups,” which obviously includes the Original Australians. With the Original people exhibiting an intense clustering into two groups, haplogroups not present in any African genes and an absence of dozens of African genetic markers, it is very difficult nigh on impossible to sustain any link between Africa and Australia."

Agreed, DNA links are important and land bridges can work both ways. Not to mention, the effect ice ages or warming periods might have on isolating or exposing populations for periods of time.

Even if a land bridge wasn't created, the sea distances which were great may have been reduced enough to permit colonization via rudimentary water craft etc.

More cousins. These guys were around a long time, and split the scene not too long ago.

The scientists estimated this ghost lineage diverged from the ancestors of Neanderthals and modern humans up to 1.02 million years ago and interbred with the ancestors of modern West Africans from 124,000 years ago up to the present day. "One limitation of our study is that we have mainly sampled present-day West African populations," Sankararaman said. They don't know yet how far the ghost lineage spread across Africa, he said.

Ghost lineages. The Neanderthals live on- within us!

I think the idea is, that some West African populations (Yoruba and Mende etc) have an ancient non neanderthal admixrure.

In that case the "non Neanderthal" lives on within those populations.

They do in lots of us in tiny amounts. But this is genetic evidence of a group of Neanderthal/modern human hybrids {for lack of a better word} in west Africa as few as 124,000 years ago. It's only showing up in west Africans so far, but that is about the only place they have been looking for it. Now they just need to find the bones to go with it.
