The Aquatic Ape theory is that humans went through an aquatic phase some
time after the split with the chimpazees. Hence we are hairless (to
streamline in water) whilst they are furry, and so on for a large number of
differences.
Most evolutionary biologists don't have much time for the Aquatic Ape
theory, but it is not so insane as to claim that humans are descended from
hippoptamuses. The analogies with other semi-aquatic mammals are to show
that the human traits the theory focuses on must also have an aquatic
explanation. So if dolphins have a lot of body fat, maybe humans have a
similar fat distribution to keep them warm whilst swimming, and so on.
