Hi Everyone
I have been surfing and found a blog on the Aquatic Ape theory, but
the person who has spoken out about it, is being attacked by those who
don't like AAT.
So i don't know if anyone here wants to help him out, if not i will
have a go.

Thanks a lot, William.
I just sent them this (I hope they¹ll approve it):

Somebody wants to defend AAT on the basis of:
1. Humans have subcutaneous fat, other primates don¹t. Other aquatic mammals
do. The fat serves as insulation.
2. Humans have almost no fur, other primates do. Other aquatic mammals
don¹t. Fur creates drag in the water.
3. Humans are bipedal. Walking upright keeps the head out of the water,
allowing breathing.
These 3 arguments can easily be dismissed:
1. Sea otters have no SC fat.
2. They have an extremely dense fur.
3. They¹re not bipedal.
And these arguments can be repeated for a lot of other (semi)aquatic
mammals.
The point is: most features that discern humans from chimps are *in
different combinations* typically seen in waterside mammals that spend a lot
of their time in the water: large brain, high sodium, iodine, DHA & water
needs, head & spine & legs on 1 line, dexterity & stone use, external nose
etc.

Humans do not spend a lot of time in water. Humans *modify* stone tools.
External nose has nothing to do with water association. Head and legs and spine
are in one line becauses humans are obligate bipedal primates. Humans are
savanna adapted as you yourself have said.

"in different combinations" is chimerical nonsense.

Another point is: all H.erectus fossils apparently lay next to shellfish.
It¹s obvious that H.erectus did not disperse on ³Savannahstan² to other
continents as some PAs postulate, but along the coasts & from there inland
along rivers & lakes. The Mojokerto skull 1.8 Ma lay in marine sediments in
a river delta, the Dmanisi population 1.8 Ma lived next to abundant
lacustrine resources etc. Why would a dextrous intelligent tool-using
thick-enameled omnivorous ape not have collected part of his foods from the
water, esp.cray- & shellfish??
Many people discussing AAT still think AAT is about australopithecines or
human ancestors millions or years ago, but this only shows how uninformed
they are.
