'Sea Nomads' Are First Known Humans Genetically Adapted To Diving (nationalgeographic.com)
schwit1 shares a report from National Geographic: Most people can hold their breath underwater for a few seconds, some for a few minutes. But a group of people called the Bajau takes free diving to the extreme, staying underwater for as long as 13 minutes at depths of around 200 feet. These nomadic people live in waters winding through the Philippines, Malaysia, and Indonesia, where they dive to hunt for fish or search for natural elements that can be used in crafts. Now, a study in the journal Cell offers the first clues that a DNA mutation for larger spleens gives the Bajau a genetic advantage for life in the deep.
Yeah, it's definitely a fetish. ;)
Anons need not reply. Questions end with a question mark.
Hazen Audel dove with these people on season 3 episode 1 called "Trial by Ocean". And, they're not really Nomads. Pretty interesting watch.

mermen?
let's be scientific about this?
Maybe after a few thousands years of living in space in the future, our species evolves the mutations necessary to combat the ill effects of micro gravity and radiation. When we push our limits in the deep, high or between, we evolve.
I think I read this about 30 years ago. I think there were stranded there from a cruise ship.
Everybody mocked it, but it's here.
From TFA: When you go hold your breath and are surrounded by water you have a bunch of physiological responses that happen automatically. One major one is that your spleen contracts delivering more red blood cells to your arteries. Since they have larger spleens, there's a larger reservoir of red blood cells ready to get pushed out when necessary.
The world record holder for underwater breath-holding is German. I guess they have these spleens too. Who knew?
not "First Known Humans Genetically Adapted to xx". And it's a direct copy of the National Geographic headline. I guess they too have no editors.

Kevin Costner scoffs at the Bajau pathetic diving abilities.
Why can't *my* society ever construct me up some gills?

Slashdot, fix the reply notifications... You won't get away with it...
a lead to my theory... follow it or not.

Going as far down as 200 feet would subject them to the bends, while coming back up, wouldn't it? I'm not a scientist or a diver, so I don't have the answer to this question.
This skill would be advantageous to my progeny.

The concept was rejected in the 1920 by everyone except the radical nationalists (including the Nazis and, to this day, the USA), because the differences were just way too small to warrant differentiating!
The differences inside "races" were often bigger than between "races"!
And genetically, it gets even worse. The concept is utterly useless, and only exists to help losers with an inferiority complex declare themselves "special", based on superficial and mostly exterior differences. Clinging to a small gentic specialization as proof, only shows how desperate and pathetic the whole thing is.
Oh, and dog "races" are the result of literally eugenics, and did not exist until the 1800s.
Another example of genetic adaptations that was discovered earlier are the Tibetans, whose homeland is a vast highland with average altitude of about 4,000 meters (13,000 feet). Having superior oxygen intake and resistance to effects like Acute Mountain Sickness helped the Tibetans to populate and defend their highland territory over the millenia. The few foreign expeditions that ever made it to their capital Lhasa were either allowed to enter (e.g. Mongols who ended up adopting Buddhism from Tibet) or didn't linger for too long.
It was only due the emergence of modern mechanized military technology (from the West) and the repressive and expansionist ideology of communism (again from West) that the newly victorious and idle armies of Mao Zedong were able to invade and actually occupy Tibet in its entirety from 1950-1951 onwards. Special thanks go to Stalin for arming the PLA, with surplus American WWII war aid also finding new somewhat less liberating uses over there.
Over the eons, sometimes as quickly as over a few millenia, people (and anything living within tolerances) are able to adapt to changing surroundings, or die trying
Technology can be used either to protect and develop life, or it can be used to destroy it.
Philosophy may seem quaint and pointless in this era of ever increasing specialization and culture of constant entertainment and distraction, but as we march into the future it would be beneficial to at least have a faint idea what it is we're doing and why.
Should invading one's peaceful neighbours be opposed, or rewarded with trade deals?

My friend's sister fell into the water some 30 years ago, and have been holding her breath ever since
Can any German top that?
This is racism! All right-thinking people know that everyone born a blank slate and good at everything and race is just a social construct.
Headlines missing out filler words that don't change their meaning? Whatever next!
Wow, did Neal Stephenson know about they before writing the book?
Every human is capable to train for 2 or more minutes diving.
I did not dive for 30 years but when I was in Thailand 2 years ago I dived like 3 or 4 minutes without any recent training.
Does not mean there is no such gene ...

There are no stupid questions, just stupid people.
I'm just an engineer, not an English major. But precision in communication is vital to engineering.
Filler words? No, it is the order that changed. "don't change their meaning"?
"First humans" would be humans that lived distantly in anthropological history. It would indeed be an interesting discovery if we found that they had been genetically adapted to deep diving by somehow extracting DNA from remains. That was my expectation after reading the title but was not what the study was about.
Phys.org's title in Genetic adaptations to diving discovered in humans for the first time was vastly better.
Yes, intelligence testing does have some roots in eugenics, but so does Planned Parenthood. Is Planned Parenthood also racist? And are things that used to be racist 100 years ago necessarily racist now?
But more to the point, the Wikipedia page on IQ testing shows a sample test question that has simple geometric shapes -- no words, numbers, or cultural symbols whatsoever! So if you can test IQ with no cultural artifacts, can you still call IQ culturally biased?
If you fail to believe there can be any hereditary basis to intelligence, it's not because you haven't seen the evidence -- it's because you've dismissed it all.

Why even bother bringing up an example? I don't know anyone who haven't tried an IQ test at least once and I suspect most people on slashdot have tried a couple of them.
They almost always have a few geometric parts like that to test spacial capabilities.
They never consist of only questions like that, that would be completely pointless since it would only measure your ability to comprehend geometric shapes.
There will also be a numeric part which will irritate anyone who studied more math than the one who put the test together.
IQ-tests aren't founded in sound science. Anyone trying to make any conclusions or even dictate policy based on them are about as scientific as anti-vaccers, homeopats and flat earthers.
No, it's not better. Clearly you're not an English major as it looks like you're probably not even literate.
It's the first _known_ humans. As in there were humans before hand, but we don't know that any of them had this adaptation. Sort of like how for so long the first known Europeans to step foot in the Americas were on those boats with Columbus, and then later on we discovered those settlements that predated Columbus by quite a while. AFAIK, they remain the first known instances of Europeans arriving in the New World, but who knows, perhaps there are older settlements that haven't yet been discovered or perhaps they settled it just long enough to load up with food to return home.
If we make it "Sea Nomads" are first humans genetically adapted to diving, it would likewise be clear that it's not the first humans, although somewhat less clearly than the way it was phrased.
That's bullshit, and I'm guessing that you didn't score very highly.
Personally, I did score highly, and I have genuine criticisms of the testing. The main being that it's just too narrow of a test to be of much use in the real world. Real world performance tends to top out somewhere in the near genius range on most of those tests.
It's also a test that can't typically be used to compare differing groups across socio-economic boundaries.
But, to say that it isn't founded in sound science is rather ridiculous. There's been a great deal of work done over the decades to improve the reliability and accuracy. Just because it sometimes fails and doesn't take into consideration the entirety of human intelligence, doesn't make the science unsound. It's primarily use for decades was to predict how far students would get in school under a certain type of schooling and it does that just fine in most cases.
