I've recently seen on television,
underwater footage of macaques diving and swimming underwater,
I mean really swimming, underwater.
Is there supposed to be something special
about diving ability in primates? --pete

Pete, some macaques dive and swim underwater dog paddling (I don't
know how much per day on average) but they live in rainforests and
remain very arboreal. Human ancestors stopped being arboreal, and
therefore did not develop the long toes which all the other apes
developed as a result of tropical rainforest arboreal living.
Dogs and tigers can be trained to dive and eat (or at least bite, I
don't know if they can swallow) underwater. google "diving tiger",
photos of tigers diving into a swimming pool attacking chunks of meat.
(I'm sure Lee would enjoy those too) DD

Yes, most(all?) tigers, many macaques & some dogs are good swimmers.
Macaques spread to SE.Asia during the Plio-Pleistocene, some presumably
along the coasts, several spp wade & even dive a bit (IIRC, the 3 spp that
reached Celebes have short tails). They evolved from terrestrial-arboreal
quadrupeds in rel.dry forests (pronograde, cursorial, above-branch...),
whereas we evolved from aquarboreal apes in swamp forests (orthograde,
vertical clmibing, arm-hanging below-branch, bipedal wading...).
