comment Can all mammals swim?
The video of the giraffes shows that they don't swim, as the moment that they consider it too deep, they instantly return to shore. And indeed, the rhino walks across the bottom of the riverbed.

Ok, seems a fair line of thought, but if this were true, why do we have flying fish (ok, not really flying, but still, they could have evolved from there)?

Thanks for the extensive answer, so there's a gap of at least ~25 million years, considering the current state of knowledge.

+1 Interesting, nice find! I just found out that hippos can't swim either, because they're too dense and would sink. They "walk" across the bottom.

@CHM: the way I see it, moving through the water without drowning and without walking on the bottom of the river/lake.

@Kevin: fair enough. Yet, to prove that all mammals can swim may require research on each of the species, but to prove the opposite only requires proof that one species really can't swim.
