How We Got Here: DNA Points to a Single Migration From Africa

We know there were multiple dispersals out of Africa, but we can trace our ancestry back to a single one.

How does that work? Everyone else died? What about recently discovered groups like the Red Deer Cave People? https://en.wikipedia.org/wiki/Red_Deer_Cave_people

Doesn't evidence exist that groups interbreed, at least Denisovans / Neanderthals / Modern Humans?

I read that as a Roanoke Colony situation.

They left, they died, they tried again until they didn't die.

I thinks it's "all extent modern humans migrated in one wave", they also bumped uglies with a few other not so modern species along the way.

Personally I want to see more study into mungo man (https://en.wikipedia.org/wiki/Lake_Mungo_remains), that has some potential to upset things.

In 1988, the skeleton of a child believed to be contemporary with Mungo man was discovered. Investigation of the remains was blocked by the 3TTG [ie. Three Traditional Tribal Groups] with the remains subsequently protected but remaining in-situ. An adult skeleton was exposed by erosion in 2005 but by late 2006 had been completely destroyed by wind and rain. This loss resulted in the indigenous custodians receiving a government grant of $735,000 to survey and improve the conservation of skeletons, hearths and middens that were eroding from the dunes. Conservation is in-situ and no research is permitted.

Sounds like the local aboriginal tribes are claiming ownership of remains that predate them, that they never knew were there anyway, and blocking further research. Thanks guys.
