Why do hippos have four toes in each foot but a rhino has only 3? I honestly don't know why one pachyderm would evolve to have an odd number of toes on each foot while another pachyderm that's closely related have an even number
>>17033346>Why do hippos have four toes in each foot but a rhino has only 3?hippos are Artiodactyls, rhinos are Perissodactyls (literally even-toed and odd-toed ungulates)Those diverged like 60 million years ago.>I honestly don't know why one pachyderm would evolve to have an odd number of toes on each foot while another pachyderm that's closely related have an even numberThey're not "closely related" at all. Pachyderm is an old obsolete classification for mammals that have thick skin.
>>17033346being underwater probably requires more control rhino toes almost look like hooves too
>>17033346Pachyderms aren’t a real clade
>>17033391Neither are dinosaurs, but people still call birds dinosaurs for some reason even though they're not a clade
>>17033399Yes but people don't complain why birds have wings and brontosaurus don't. Because they diverged millions of years ago. You can use made up terms but you can't use made up terms to whine why the made up term isn't giving you useful information.
>>17033399Yes they are retard. Birds being part of Dinosauria is a monophyletic grouping
>>17033399I don’t think you know what a clade is anon
>>17033346Hippos are better than rhinos, so they get to have an extra toe.
What's the selective pressure for feet though, that's kind of interesting. Especially why do humans have so soft useless feet that we uselessly just use to walk on?
>>17033346are you the "why do we have two nostrils instead of just one big one?" tard?
>>17033399>/sci/ fails at taxonomyEvery time
>>17033934No
>>17033896>Especially why do humans have so soft useless feet that we uselessly just use to walk on?so our tongues dont hurt when we lick soft female feet
