Boffo beringia ping.
Bump for later.
Ripan is one of the students who came out of Dave Smith's lab at U.C. Davis. Smith and these graduates and their students are doing some of the most interesting DNA work around!
A very interesting article. I have always believed North American Indians had an appearance that resembled Asian ancestry, as opposed to European/Middle Eastern.
Yeah, the graphics are super. But it doesn’t tell the whole story.
Forty thousand years ago humans migrated into Australia. So, how did they get there without boats?
Australia hasn’t been attached to any Asian continental landmasses nor to the large island to its north, modern day New Guinea. Yet humans and domesticated dogs arrived in Australia 40,000 years ago. They obviously arrived on boats of some kind.
During these past 40,000 years the sea level world-wide was between 600 to 400 feet lower than it is today. Look on any detailed submarine topographical map (one labeled with depths) and you’ll note how much of the mid-Atlantic ridge and other seamounts would have been bare land. An astonishingly large number.
If humans could have made it to Australia by boat 40,000 years ago, why not island hop across the Atlantic from west Africa? Is that why the boats made of reeds used on Lake Titicaca look almost identical to boats made of reeds depicted in ancient Egyptian tombs?

Of interest?
So, like, let me get this straight...
There was a way to walk between the two continents? And the weather was cold enough that ice was walkable between the two countries? Then it was warm enough for people to actually live in those areas? But it was cold enough to walk?
And none of this was caused by SUVs and coal-fired power plants?

I heard a theory, long ago, probably on TV, so probably garbage, but it did seem to make sense to my uneducated self.
It went something like...
Boats. The earliest migrants to the Americas came across the water in the same kind of boats that are still made in the arctic cultures.
These were migratory peoples by custom. They originally settled along the coast all the way down the line. They were kept close to the coasts by both habit and by the megafauna. I believe one of the principle critters held responsible was the “God Bear”. A big huge monster of a bear that skeletal remains indicate could move very quickly and might have even been an endurance runner type.
It was only after something crunched the mega fauna that humans began to move away from the coasts.
I do wonder what would snuff the mega monsters but not the humans.
It strikes me as curious that people would “pause” so far north during a glacial max and not move south toward warmer climes. Maybe it was the food. The Alaskan fisheries are among the most productive in the world. The megafauna was probably good too.
