Lot's of species eat this diet, you fucking moron.

What percentage of the human brain is DHA? Where did it come from?
Answer my question, you evasive piece of shit. Explain why the hundreds of DHA consuming species didn't develop hominid/human evolution?My little little boy, why do evase the answers?? why don't you grow up??
Answer my question, you evasive twit.
Do you really believe the 100s of DHA-consuming spp were aquarboreal??
- Mio-Pliocene hominoid evolution, google "aquarboreal",
- Plio-Pleistocene Homo, google "coastal dispersal Pleistocene Homo".
Answer the question you evasive piece of shit. Explain why your theory that DHA causes hominid evolution

Evolution happens. Environments change, species go extinct while others
have the genetic diversity necessary to adapt.
But DHA is necessary. We evolved to need it.
And as lousy as we are at
synthesizing it, men worse than women, our ancestors were a lot worse.
We have DHA dependent brains. We arose from an evolutionary process
where DHA was plentiful enough so that we could physically rely on it.

Again, DHA is the key. It's proof that Aquatic Ape is right. There was no other source for the DHA other than Aquatic Ape, and we evolved in an environment with plentiful DHA.
Until we evolved a means to better synthesize DHA -- and we're not good at it, merely "Better" than our deep ancestors were -- we were reliant on external
sources.
Actually, humans are STILL reliant on external sources. We just plain don't make enough for optimum brain health...
Anyway, we all know what that external source was: Aquatic Ape.
They exploited marine resources.
And as lousy as we are at it, the molecular dating crowd says we only got THIS good about 80k years ago. So for all of the history of our genus, up to 80 thousand years ago, we were dependent upon marine resources.
Aquatic Ape. There is no other explanation that comes close.

Perhaps "coastal dispersal" is a better term?

The problem very clearly isn't what term we use. It's a refusal to
think beyond the dogma.
I can imagine, these wingnuts, hearing "Coastal Dispersal" and
insisting that we're saying that their goal was to disperse
across the land masses, and exploiting marine resources was
a way they thought up to accomplish that...
The weren't "Dispersing." They were eating. They were living,
surviving on abundant protein. As a consequence to that groups
were going to get "Left Behind" -- push inland, following fresh
water outlets, transitional wetlands (etc) into the interior where
they adapted to the new environment.
As for "Two" hypothesis:
I'm incorporating Aquatic Ape, Multi Regionalism/Regional
Continuity, Punctuated Equilibrium, Interbreeding (Hybridization?).
I'm sure there's something I'm forgetting right now...
Oo! Even r/K Selection, though clearly not on the scale some folks
imagine. But there clearly were different "Reproductive Strategies."
These were culture, of course, but they shaped the physical...
So that's at least five.
