Why can't humans WALK from birth? Obviously, we must not be land animals.
Seriously, human infants can swim. I once saw a video of an experiment in which a young infant was put in water, and it instinctively began kicking and paddling with its arms. Apparently, this ability disappears rather quickly in an early child's development, unless it is nurtured. I understand that it disappears entirely after the first six months or so.
Moreover, the Aquatic Ape theory holds that we (obviously) never completed the transition to a purely aquatic species, like whales, or even sea lions.
Glad you brought that up.
Have you noticed that only the fully aquatic cetaceans have shed their body hair? But isn't the aquatic lifestyle Elaine Morgan's explanation for why humans are almost hairless?
Further, we've got all kinds of fossils of the various families of aquatic mammals. Water is good for fossil-making.
Where are the aquatic ape fossils?
