Explain this shit (human evolution)

[Anonymous No.3108457]

Here's something I always wondered.

Most scientists agree the cradle of mankind was Africa. This explains people living in Africa (obviously) and people living in Europe and Asia, early humans being nomad and shit.

But what about native Americans? Polynesians? Aborigines, etc.

Those couldn't possibly have crosses the oceans. The evolution of man also happened long after Pangaea so they couldn't predate the shifting of the continents. Did they just evolve in parallel and independently into perfectly genetically identical/compatible humans or am I missing something?

TL;DR where the fuck do all humans come from.

herp derp we crossed the atlantic on a bridge of ice along with tonnes of other animals and there is ample scientific evidence for this.

Migration. Especially once we figured out how boats work.

[Anonymous No.3108473]

It was migration.. Boat technology has been around for 15,000 years at least

Boats! There is also some arguments that South America was populated in a similar way.

[Anonymous No.3108496]

Hawaii is in Polynesia,so someone doesn't understand geography .. If you can migrate to Polynesia, you can migrate to Hawaii.. Derp derp.

Water has never been a barrier to human migration patterns. I know this is a shock to religitards.. Quit underestimating human creativity, boat technology has been around for 15,000 years.

There's a long string of islands between Asia and Australia.

Likely came from Polynesia.

How would flimsy boats be able to cross oceans then? Wouldn't the waves be too strong?

It isn't /sci/'s job to educate you. Go to the library for once.

Hawaii will always confuse me.

The only way that I can imagine it getting populated is if a boat full of Polynesians got lost at sea, managed to get to land and commit copious amounts of incest.

a man (an anthropologist I believe, but don't quote me on that) already proved that it was possible to sail across the Atlantic in a reed boat...by being a badass and doing it himself.

Or they came across the glacial land bridge then later traveled a short distance from the American continent.

right?

[Anonymous No.3108623]

The ocean changes shape often in a geological sense. There was constant migration among the many land bridges that used to exist. The bridge between NA and Asia wasn't the only one. Plus boats helped cross expansions of water, though many populations became isolated to a large change in sea level.

Finally a chance to use this map, I don't even care if it's a troll thread.

Shows the variation certain genes of the y-chromosome. You can pretty much track the path of ancient man looking at the genotype of indigenous populations.

Bearing Strait up in this bitch

[Anonymous No.3108700]

60-120 thousand years ago (When people migrated to Australia and the Americas), they didn't have to cross the oceans as there were land bridges. There were great herds of animals to hunt, fruits to pick, and fish to catch.

Also they must have been able to cross the oceans, or else there wouldn't be people all over the pacific.

>>Implying that skull shape has anything to do with a human's value beyond beauty

What you should be bringing up is the lower IQ of the Aborigine, and their smaller less complicated brains.

Also despite physical differences, science defines the borders of a species as all individuals that can breed with one another and produce fertile offspring. So Aborigines are distinctly human.
