Is the hippo going into the sea, or coming on land?

Answer 1

evidence, first from blood proteins, then from molecular systematics, and more recently from the fossil record, show that their closest living relatives are cetaceans – whales, porpoises and the like . Hippopotami have more in common with whales than they do with other artiodactyls (even-toed ungulates), such as pigs. Thus, the common ancestor of hippos and whales existed after the branch-off from ruminants, which occurred after the divergence from the rest of the even-toed ungulates, including pigs. While the whale and hippo are each other's closest living relatives, their lineages split very soon after their divergence from the rest of the even-toed ungulates.

Answer 2

it's just messing about in the mud. But yep, it is closely related to whales. And there's a crazy extinct bunch called the mesonychids kicking about there somewhere. The group containing whales and hippos is called the WHIPPOS!

Answer 3

If this is a question about evolution I think you've misunderstood some very basic principles.

You'd have to consider selection pressures in either direction. I'd say there are few at the moment, they're suited to amphibious life like the crocodiles they share many rivers with - now they haven't changed much in over 100,000,000 years.

Evolution says 'if it aint broke, dont fix it'.

Answer 4

i will hazard a guess that its coming onto land
hope this helps
