I think, for the most part that donkeys are a little bit smarter. Like others have said, more common sense.
@its lbs not miles
I think that you meant species.
Donkey's and horses are from the same family of Equidae and same genus Equus. They separate at the species E. ferus (horse) E. africanus (wild asss) and then sub species is the donkey.
You are right about the dog and wolf. They do not separate until sub species. Dog is considered a sub species of wolf.
LOL Very true, but I figure it was easier to keep it in simpler (although technically incorrect) terms since most people aren't likely to be as familiar with the evolutionary paths taken (which show that the unicorn is not really a myth....we just messed up on part of it's evolutionary path and know it better as a rhino) :)). We could go into the fact that every species of Equus has a different number of chromosomes (including the truly wild horse as opposed to the feral horses that we call wild and the various specie of zebra each having different numbers so we can't say that all zebras have the same). Or that because of the differences in the number of chromosomes it has been widely (and still is often) believed that cross breeding will not produce viable offspring, but too is not true. They are generally no viable, but there are cases where correct chromosomes line up between the mating of a donkey and horse, producing a fully viable offspring that was capable of being bred and producing offspring.
But technically you are absolutely correct and I should have said the they are a different specie of the Equus genus, of the Equidae family of the Perissodactyla order (which is where the rhinos branched out from).
As for dog and wolf, I've always thought it was ridiculous to even break them down as a subspecies since their chromosome make up is identical. Only real difference is that one is domesticated and the other is not (dogs are just very confused wolves LOL). I'm waiting for someone to decide that each breed of canis lupus familiaris (AKA the domestic dog) is it's own sub specie and we can just stop using the term "breeds".
Now everyone study the Perissodactyla order's (not to be confused with Pterodactyl or Pteropodidae) evolutionary branches for the test on Wednesday. You can hand it a break down on the evolutionary history of order carnivora, family Canidae, genus canis, and explain why the dog was named under the lupus specie and not the rufus specie (which is why think they're going to eventually make each breed of familiaris it's own sub specie) LOL I couldn't resist.
I hope everyone took notes. Make sure you understand the material. It's not as confusing as it sounds (ok, it might be as confusing as it sounds LOL).
Sometimes I think I shouldn't have retired....nah, not really....I never regret it LOL.
