pp.39-40:
The human body responds to extreme breath-holding (CO2 build-up) in 3 stages: 1) Muscular contractions:
you’ve only got a few minutes to go before you really need to breathe.
2) The spleen releases up to15 % O2-rich blood into the blood-stream, when the body goes into shock: low BP, tachycardia, organ shutdown (also during extreme breath-holding):
a free-diver anticipates the spleen’s delivery of fresh blood, feels it happen, and uses it as a turbo-charge to dive even deeper.
3) Blackout, when senses that there’s not enough O2 for it to support itself, and so shuts off, like a light switch, to conserve energy.
(The presence of liquid in the mouth or throat triggers another reflexive line of defense: the larynx automatically closes, stopping water from entering the lungs.)
Free-divers learn to sense muscular contractions (1) & spleen release (2):
they know exactly went head back to the surface so blackout (3) won’t occur. A free-diver survives by understanding & respecting these mechanisms.

Not to tax your clearly over burdened mind any more than it already is
but, do you have any clue how reality works? Any at all?

Rarely does a single data point, a single isolated piece of evidence
make a compelling case for anything, most less constitute "Proof."
You need look no further than the transcript of any criminal trial, a
murder case perhaps. You're never ever going to see a case, for
example, where a prosecutor's sole piece of "Evidence" is a foot print
that matches a brand of show known to be owned by the defendant...

"He and only 10,000 other people within 100 miles own a pair like that,
so convict him & sentence him to death for murder!"

Things don't work that way. Reality doesn't work the way your trolling
is pretending.

Yes, humans can hold their breath.

Yes, we find physical evidence of diving, or habitual entrance to water ("Surfer's Ear").

Yes even our eyes appear to be adapted to diving:

https://groups.google.com/g/sci.anthropology.paleo/c/1CB2jBhnuyU/m/O6uTNqIoBQAJ

As pathetic as our ability to synthesize DHA is, it never got this good
until adaptations arose far too late for claims of "Modern Humans,"
not just suggesting but one might argue necessitating a seafood diet.

Aquatic Ape is NECESSARY for "Coastal Dispersal."

Coastal Dispersal is explained by Aquatic Ape: They were eating, then
moving on to better pickings just as soon as the food sources grew a
little scarce. They weren't looking for an all night burger king, they were just eating.

This impromptu "Migrating" would have resulting in their arriving
everywhere from Oceania to southern Africa!

Groups occasionally being forced inland, following water sources inland,
due to conflict, over population, natural disasters, disease and even the glacial/interglacial cycle would have resulting in unique populations of
Homo, exactly as we see, as they adapted to their new found conditions.

Wow. The more we look, the more everything folds together, exactly the
way savanna idiocy does not.

There's a CULMINATION of evidence, some of it circumstantial (the way
it all works together) and some of it direct, like the surfer's ear, or the dispersal of Homo while remaining one species, able to interbreed.

What do savanna idiots say? Something about "Domeshields" and "That's
how!"

Yes, humans can hold their breath.

And their shit too, which is why some people are full of it.

It's a environmentally induced medical condition, which is usually not
an indication of a species-level adaptation.

1) Muscular contractions: you�ve only got a few minutes to go before you really need to breathe.
2) The spleen releases up to15 % O2-rich blood into the blood-stream + low BP, tachycardia & organ shutdown.

If we really were meant to be underwater we wouldn't need all those
defenses. They're physiological emergency measures, that may save your
life.

Speaking of which; map it out. Map out this savanna idiocy model.

Go on. STOP pretending that everything happens in isolation, instead
of comprising a single stitch within a tapestry. Do it.

You want to pretend you have something other than Aquatic Ape, a
better model, so go ahead and map it out. Nobody is going to stop
you. Nobody can stop you. We can and will point & laugh, pretending
you have the balls to do it, but this is how real life works.

Aquatic Ape isn't dependent on any one person or piece of evidence.
Homo didn't drop out of the sky, fully formed, only to spread unchanged.
THAT is your stupid model. If you want to pretend otherwise, map it out
for us.

All the pieces fit together with Aquatic Ape.

My little little little boy (when are you to grow up??), nobody here speaks of deep diving!
- sigh
Why don't savanna believers inform a little bit before trying to say something??

e.g.
Conference: Homo litoralis:
Pleistocene diaspora along coasts and rivers
St.Paul's Hotel London 8-10 May 2013 - Peter Rhys Evans

Early-Pleistocene archaic Homo spread intercontinentally following African & Eurasian coasts & rivers, feeding predom. on shallow-aquatic foods, esp. shellfish, which are extremely rich in brain-specific nutrients:
LC-PUFAs e.g. DHA, taurine, iodine, oligo-elements etc.
Most anatomical innovations in H.erectus (vs earlier hominids such as australopiths) are typically or uniquely seen in littoral mammals:
- brain expansion,
- platycephaly,
- pachyosteosclerosis,
- external nose,
- ear exostoses,
- very large lungs,
- wide body,
- platymeria,
- etc.etc.
Every one of these already proves the littoral theory!

With notes on early colonizations of overseas islands (Flores, Sulawezi, Luzon, Cyprus, Crete, Dodekanesos etc.) & rudiments of littoral adaptations in extant humans:
- fur loss,
- panniculus adiposus,
- aligned body, pin-hole pupils underwater,
- olfactory reduction,
- etc.etc.etc.

Only incredible imbeciles believe their Pleistocene ancestors ran after antelopes!
Only incredible imbeciles deny our Pleistocene ancestors followed coasts & rivers!

Fur loss (MV bald as a baby!) :DDDD
Human scalp hair is as dense as chimps, but grows much longer, due to selection for piggyback riding of babies while foraging bipedally. Body hair reduced due to sleeping in nocturnal dome shelters of course, unlike arboreal apes that sleep exposed to
night-time breezes while asleep. All seals have dense inner fur and guard hair, like sea otters, even those in tropics of human size.

The diving/swimming would have been an enormous advantage during an interglacial
phase.

The waters rise, at some points rather quickly, and at various places along the coast
they are stuck, no longer able to cross what was once an open stretch of beach.

Diving/swimming might've allowed them to cross just the same.

Diving/swimming might've increased the exploitable sea floor, so less ocean froont
could feed them for a longer period of time.

Another FACT we know about humans as they don't want to just eat, they want to enjoy their foods. They favor some sources over others, purely on taste, without
regard for even economics!

This is a trait that permeates all of human society. People for whom a Toyota Corolla would meet or exceed every need run out and buy a Mercedes or BMW...

Clothing. Housing. Decorative Baubles..

The thought that they wouldn't invest extra time and efforts -- like diving -- in
order to secure a favored food is preposterous. They did it. Period.

Not that paleo anthropology has ever been a real science, nor it's

You wouldn't pass muster on a high school debating team!

You don't seem to know WHAT to argue, WHAT matters here and

You're emotional: Visceral, not analytical.

Why your emotional outburst can't ever be mistaken for a real
"Argument" is because you're attacking a person, unable to find
fault in a single thing they say.

Much of the past is unknown and unknowable. As I once described
it in a thread; it's a it like view a wallet sized photo from 10 feet away.
We can gleam a lot from the image, but we miss all the final details.

It's like this for everything in the paleo world, even if you savanna
idiots insist that it's not.

Yes, possible.
Mio-Pliocene hominoidea were aquarboreal, but did they also already dive sometimes??
Until then, Hominoidea were AFAWK exclusively (sub)tropical?
But when Tps dropped (Pleistocene), this apparently had profound effects: more/different shellfish? growing on different places? more abundant deeper?? Did frequent diving (POS, large brain, ear exostoses...) began only Pleistocene?
Did interglacials "allow" Homo to colonize temperate regions?
