According to the BBC2 "Nightmares Of Nature" series more people die from
being attacked by hippos than by crocodiles nowadays, so it could be
argued that ape-men who hung around water-holes in the savannah-mosaic
environment would have been in more trouble from hippo-attack than the
aquatic apes in the croc-infested sea.
