They have not been taught to equalise? That seems weird as that is something that kind of comes natural for someone that spends a lot of time under water. That they would have been diving deep for hundreds and hundreds of years without learning the most fundamental bit, equalizing. Seems far fetched to me.
The greek sponge divers would just blow their ear drums as kids as well.. i guess when your lively hood involves diving 100s of times per day hearing can maybe be lowered on the priority list.They have not been taught to equalise?

The general way reports on freediving go.. maybe a Bajau did a 13 min static (probably not) and his friend did a 60m dive with fins+rope (very likely) reporters will mix the two and write that a naked, finless, maskless, and deaf guy did 13 mins to 60m because it looks cooler on paper.https://news.nationalgeographic.com/2018/04/bajau-sea-nomads-free-diving-spleen-science/
Nat Geo was pretty impressed with their diving. Apparently they're doing 13 minutes hangs at 60m.
This people have spent so much time under water that their bodies have evolved to the extent that their spleens are enlarged, how the hell is it possible for them to avoid learning equalizing for hundreds and hundreds of years!? It's pretty self-explanatory if you spend so much time under water; you hear it, you feel it, and it is easily replicated once you learn it. Seems pretty unavoidable to me.
A very interesting Bill article and it would be more interesting if they could find out how long ago this change occured in the Bajau as if it were from the 1600s then it would show that humans can evolve to certain conditions/enviroments very quickly but to prove this so you would need a Bajau spleen that is three to four hundred years old.
Although the Bajau can dive deep they do have other problems and ruptured ear drums at a young age is one of them as they have not been taught to equalise.

I agree. You would think they would have learned it by accident after hundreds of years.
Thanks PrimeMerian a good bit of info about the Bajau. I find it strange that we are usually taught as children that explorers such as Cook and Columbus were the first to find certain continents and Islands but if there are already native people living there then obviously it was discovered at least by those native peoples if not before them. And why we were not taught at school for instance that the Viking Leif Erikson set foot on American soil in the early 10th century almost 500 years before Columbus got there makes me think that even though the Archaeological site at L’Anse aux Meadows was found in 1960 that they just couldn't be bothered to change this fact in the schooling twenty five years later.Aloha Brochman, a few years back archaeologists found a bottle of Portuguese Port from the 1500s in Darwin Bay, Northern Australia. In a rock shelter near the bay, they found paintings of a square-rigged ship and of a boat with similar rigging to what the Bajau still use. It is suspected that the Portuguese traded port with the Chinese and then the Chinese traded the port with the Bajau for the sea cucumbers they harvested. It was the Bajau who are suspected of throwing the empty port bottle overboard into Darwin Bay. All this 200 years before Captain Cook. Aloha
