Hey Guest, Early bird pricing on the Summer Moot (29th July - 10th August) available until April 6th, we'd love you to come. PLEASE CLICK HERE to early bird price and get more information.
Yes, Africa has water, but the people I mentioned live in what is classified as 'arid' lands....unlike the Dutch who would drown without their sea dykes.

Ok you right so " some" young bajau intentionally rupture there eardrums to become better divers how long have they done this for I wonder.Simplest one I can find.

Never. There is no such thing as a fact. This is why the sciences refer to theories.
What we “know” is our best interpretation of the current evidence.
There is some indication that some of our ancestors might have been somewhat more aquatic than are we currently at some point in time. Not enough evidence to say “all” or “did”.

I’m going to butt out after this honest:
The Sun is managing perfectly well without oxygen.
Yes but fire by friction requires oxygen and that is a fact but you claim there are no facts in science.
Nuclear fusion and a camp fire are two separate things at least I think so maybe I'm wrong .
My point about monkeys swimming was in response to a comment about them not swimming and it being a human thing to swim thus supporting the AAH. I believe there's other monkeys without proboscis who swim I just happened upon that new scientist article first.
The actual origins of the proboscis is believed to be related to vocalisation and selection by females for reproduction. Apparently the larger, male proboscis produces a deeper call than shorter female or juvenile ones. They are a very vocal monkey species!
I live in Scotland. I used to do a lot of swimming, but even as a good swimmer, I couldn't stay in our waters long. It's just too cold. It saps the heat, etc.,
The folks who do the channel swim and so on, they cover themselves in all kinds of things and they acclimatise themselves to the temperature.
That's the crucial part of all this; humanity can acclimatise to a degree to suit many different niches and habitats.
Note, acclimatise not evolve....though one could argue for the blood properties of the folks who live high enough that the air is thin.....

Yes humans are tropical animals the theory pertains to that environment the bajau n moken are tropical I think a sealskin wetsuit is not a bad idea though.
Outside off the tropics we need clothing so your right the acclimated argument can apply to everywhere except the tropics
.....and yet, humanity is found, and has been found in every continent, and every range of temperatures there.
Most of us carry Neanderthal genes....those people lived in some pretty cold bits of Europe, but then humans still do. The Siberians for instance, the Mongolians for another.
It's the 'evolve' bit that causes problems with the discussion.
The ability to live and work and breed in low oxygen heights is an evolved characteristic; the double eyelid is an evolved characteristic, but we haven't evolved waterproof skins or ears......

The Tierra del Fuegians might fit your criteria .....

Okay, that's stretching it a bit, 900km of rough seas......
We know the Kawesqar's were canoe builders/sailors though. Whether they ventured down the island chains and over.....who knows ?
We didn't used to believe that the Vikings had reached America. There are Maori stories of the ice continent though.
We'd need evidences, and though ice preserves, it moves and it ends up either buried in more ice or melted at sea.

The Yahgan may have been driven to the inhospitable Tierra del Fuego by enemies to the north. They were renowned for their complete indifference to the cold weather.[11] Although they had fires and small domed shelters, they routinely went about completely naked, and the women swam in cold waters hunting for shellfish.[12] They were often observed to sleep in the open, completely unsheltered and unclothed, while the Europeans shivered under blankets.[8] A Chilean researcher claimed their average body temperature was warmer than that of a European by at least one degree.[10]The Tierra del Fuegians might fit your criteria .....
