You need to point the Google thing at: Non sequitur

"Wait. Running is an emergent trait? That means they
were eaten by lions!"

As opposed to being eaten by sharks because we
are terible swimmers and can't breath water?

Birds are bipedal and can run on the ground quickly, but
the rest of the time they WALK.

Ironically enough, nearly all of bird anatomy is explained
by the fact that they descend from bipedal, terrestrial
dinosaurs that grew feathers or feather like thingies.

All aquatic mammals are short limbed quadrupeds.

"Thingies" is a technical term.

For people who only went to film school.

I forget names here but, supposedly the link between
dinosaurs and birds first arose during the course of a
chicken dinner -- noting the similarities.

So, yes, humans really are descended from the Aquatic
Ape the same way that birds are descended from ground
living dinosaurs.

Except that all aquatic mammals are short limbed quadrupeds.

Swimming and diving are Atypical.

That's not true. Just visit a beach or pool on any clear
summer day.

You need a beach or pool? Walkers and runners merely
have to go about their home or go outside. THAT is
typical.

It's also not true that swimming and diving were ever
required. Aquatic Ape would have it's roots many millions
of years ago -- 10 or 20 million years -- and the good
doctor points to his evidence of diving in, what? Erectus?
Neanderthals?

I'm guessing they could have spent millions of years just
picking up food and eating it -- shellfish, anything beached
they could scavenge. Diving, real diving -- as opposed to
going underwater -- probably arose during interglacials,
as rising sea levels turned lands into islands and blocked
what was otherwise a clear path along the water's edge.

"swimming and diving" not required - there it is, folks!

Then WHAT on Crom's bloody earth would make them aquatic?

Go look up: hunters and gatherers.

Okay I did. I didn't see you anywhere.

And you didn't see any swimmers and divers either.

There is no equivalent for swimming and diving.

It's not entirely unique, but it's certainly close to unique.
So it's something /Almost/ unique to humans and
that requires a DIFFERENT environment or set of
evolutionary pressures on humans, or order for this
behavior to exist in humans but not Chimps or Gorillas.

Aquatic Ape.

Unique?

ALL aquatic mammals are short limbed quadrupeds. Not
one otter or beaver or walrus is bipedal.
