Excuse me, if the baby is on its back (I assume because it can't breath
otherwise) then its legs and arms are in the air, how do these "paddles"
push the water? Also, limb joints naturally restrict the range of limb
motions to ones that will generate a forward motion if the resistance is
small enough; this is true of all limbed animals (2 & 4). How does
that equate with your innate ability (that had to be specifically
adapted) to swim? The motions a baby makes are those of a land
creature (walking/crawling/swinging) not those of a swimmer. (compare
the difference in speed & efficiency between a dogpaddle and the
modern freestyle or butterfly, a baby could barely dogpaddle while
to move quickly enough for possible escape in the water you need the
motions af the freestyle or butterfly.

Most primates require extended natal care periods, we should not
compare humans, protohumans, etc to antelope, horses, and other
extremely distant mammal types when comparing survival tactics. If
we stay within the primates or even better, within the anthropoids
we see the real comparisons.

Actually we seldom ignore the evidence, but we do often value it less
because of problems such as poor comparisons, or inattention to detail.
We do try to be objective, if we fail sometimes remember we are human.
