Well, to tell the truth, yeah, they all have a common ancestor, but it
wouldn't have been anything we would recognize as a "hoofed" mammal (after
all, it would be our ancestor as well!)
You don't think hyraxes, perissodactyls, artiodactyls, cetaceans and
elephants could belong to a clade of mammals that excludes primates? I
think they can. Further, the common ancestor of the aforementioned
ungulates and "subungulates" probably would have had unguals that were
"hoof-like". (I was using "hoofed" in a very general sense - the way
hyraxes and elephants are.)
