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

AAT s.s. is based on human behavior/anatomy/physiology/DNA compared to chimps & living animals:
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: brain size, slow-diving skills, breath control, small mouth & biting muscles, tongue bone descent, projecting nose, poor sense of smell, handiness/tools, late puberty, alined head-spine-legs, flat feet, fur loss, fat, sweat, less climbing, high needs of water/sodium/iodine/poly-unsat.FAs(DHA)... - features present in different combinations in (semi)aquatic animals, absent in typical savanna mammals.

Homo & Pan split ~5 Ma. Homo populations spread along lakes/shores/rivers in savannas & elsewhere, eg, crossed 18 km sea to Flores 0.8 Ma: tools/fossils 2.5-0.1 Ma are found amid seashells near Rift valley lakes & even (sea level fluctuations hindered fossilisation) Indian Ocean & African coasts: Mojokerto, Dungo V Baia Farta, Terra Amata, Table Bay, Eritrea... Glacials = maximal aquaticness?
