I can't let this one go unchallenged!

Face to face copulation is not universal among human cultures.
Swimming has to be taught (a process that is sometimes traumatic),
and many, perhaps most, human beings never learn to swim. The idea
that all characteristics of an organism must be the direct result of
adaptive selection is roundly criticised in

Gould, S.J. and R.C. Lewontin. 1979. The spandrels of San Marco
and the Panglossian paradigm: a critique of the adaptionist
programme. Proc. R. Soc. Lond. B 205:581-598.

This is a paper you should definitely read.

And don't forget that horses, dogs and cats can all swim too :-).
