Re: wetloon slanders Sir Hardy

....

- I never said "hominids" passed through any phase
- I never said our ancestors passed through an aq.phase

netloon:
A typical wetloon non-explanation that explains nothing.
A real biologist, Sir Hardy (1960) said:
 "I ventured to suggest a new hypothesis of Man's origin from more
aquatic ape-like
 ancesors. I suppose that they were forced into the water just as we
have seen happen in so many other groups of terrestrial animals."

well-said - nothing wrong:

AAT: Shore Adaptations in the genus Homo
-Human Evolution based on Comparative anatomy/physiology
-Littoral Diaspora after Homo & Pan split ~5 Ma
-Comparative & Fossil information on ape & human evolution

AAT:
-Aquatic Ape Theory of human evolution (original term E.Morgan 1982)
-Aquarboreal Apes Theory of Mio-Pliocene apes (aqua=water arbor=tree)
-Amphibious Ancestors Theory of Plio-Pleistocene Homo (AAT strict sense)

AAT s.s. is based on human biology compared to chimps & living animals
(behavior/anatomy/physiology/DNA):
Waterside food collection (fruits/(coco)nuts, turtle/bird eggs,
shell/crayfish, water(side)plants, drowned bovids, stranded whales...)
explains unique Homo traits (not in apes/australopiths) better than forest
or plains dwelling:
-large brain (frequent in water(side) mammals),
-slow-diving skills (record >100 m! typical for divers for sessile foods),
-voluntary breath control (record >10 min.!), preadaptation for speech),
-small mouth & biting muscles (suction feeding?),
-tongue bone descent (suction feeding?),
-projecting nose (in semi-aquatics),
-poor sense of smell (disproves savanna dwelling),
-handiness/tools (thick enamel, durophagy, common in waterside mammals),
-late puberty & long life span (opposite of savanna mammals),
-alined head-spine-legs (water resistance),
-flat feet (disprove savanna dwelling),
-fur loss (frequent in tropical (semi)aquatics),
-fatness (typical of species that spend a lot oftime in water),
-reduced climbing,
-profuse sweating (as in sealions on land, requires water & sodum, scarce on
savannas),
-high needs of water (drinking, low renal concentration),
-high needs of sodium (esp.seaside),
-high needs of iodine (coast),
-poly-unsaturated fatty acids (eg, DHA), in abundance in aquatic foods,
-etc.
All these features are present *in different combinations* in (semi)aquatic
animals, but strikingly absent in typical savanna mammals.

After Homo & Pan split ~6­4 Ma, Homo populations spread along seashores &
inland along lakes/rivers in savannas & elsewhere, eg, crossed 18 km sea to
Flores 0.8 Ma: tools/fossils 2.5-0.1 Ma are found near Rift valley lakes &
even (sea level fluctuations hindered fossilisation) Indian Ocean & African
coasts, often amid seashells: Mojokerto, Dungo V Baia Farta, Terra Amata,
Table Bay, Eritrea...
