What’s the big difference between zebras and horses. To me they look exactly alike (aside from there color schemes), but I’ve heard that they are as different from each other as humans are from chimpanzees. Is this true? Also, while we’re on the subject, why is it that we never see people riding zebras like they do horses; are zebras untameable? These questions have been bugging me for dacades.
Check out an essay by Stephen Jay Gould, the paleontolgist. He has a brilliant articel about in in one of his books. If you want, I’ll search through my collection, and get you the title, but right now i’m kind of drive-by posting.
Welcome to the SDMB.
Here is a web site that should answer most of your questions.

The zebra belongs to the same family as the horses and ponies.
I can’t remember the breakdown between family, species, genus, ect. but maybe someone will explain that to you.
No, that’s not true at all. Zebras and horses belong to the same genus (Equus) and are so closely related that they are capable of interbreeding.
Very few things are untameable, it’s just that zebras are much more untameable than horses. And they have a nasty disposition and a love of biting people that come near them to boot. If you put enough effort into it, I’m sure you could tame a zebra but I don’t think it would be worth it.
The thought of riding one probably never even occurred to the African natives due to the nasty disposition of our striped friends.
BTW, the essay is “What, If Anything, Is a Zebra” in the “Hen’s Teeth” collection.
Zebra Home Page tells the difference between types of zebras.
This site gives the various genus/species for equus (horse) with links to Google searches.
Scroll down [url=http://www.geocities.com/poitouthor/welcome.html] for information on riding and breeding zebras.
One short explanation I saw said this, “You’ve got Zebra and you’ve got Horses.
Equus zebra is the Mountain zebra and Equus burchelli is the common African or Plains zebra, they both have wide stripes. Grevy’s zebra, with thin strips, is Equus grevy. And the modern horse is Equus caballus.
What is it about horses that humans can take them and mould the horse’s personality? Riding, jumping, pulling stuff. Nobody does any of that with any of the zebras. And I can’t believe it’s from a lack of trying, either…
After all, humans have bred hundreds of different breeds of horses, including several different color breeds. Like the Paint and Appaloosa. Humans are delighted with color. Why wouldn’t we want to ride someone as flashy as a zebra?
But you don’t see anyone riding zebras… because they are wild. Not domesticated.”
By the way, welcome to Straight Dope Message Board.
A modern horse is Equus caballus, member of family Equidae in order Perissodactyla (which also includes rhinos and tapirs).
There is also Przewalski’s horse, which is either Equus caballus przewalski (which would make it a subspecies of the modern horse species) or Equus ferus przewalski or Equus przewalski (therefore constituting a separate species).
Equus is the only extant genus in this order.
There are three species of zebras:
[ul][li]Equus zebra, the mountain zebra[/li][li]Equus burchelli, the plains zebra[/li][li]Equus grevyi, Grevy’s zebra[/li][/ul]
Equus quagga is now extinct.
There are three species of ass, also in Equus:
[ul][li]Equus hemionus, the Asiatic wild ass[/li][li]Equus asinus, the African wild ass (and also modern donkeys and burros)[/li][li]Equus kiang, the Kiang[/li][/ul]
Equus africus is considered to be synonymous with Equus asinus.
Equus onager, the Onager, is now considered a subspecies of Equus hemionus.
This site discusses the rarity of these species in the wild.
Jared Diamond discusses attempts to domesticate zebras at some length in Guns, Germs, and Steel. As he puts it, “the eight species of wild equids vary greatly in disposition, even though all eight are genetically so close to each other that they will interbreed and produce healthy (though usually sterile) offspring”. And all four species of zebra are “irascible”, “impossibly dangerous as they grow older”, impossible to lasso, and bite a lot.
I suspect the bottom line question here is: if you had some sort of polarized lenses so that you couldn’t see the stripes on the zebras, could you tell by looking whether a particular critter was a zebra or a horse.
None of the websites shown so far address that directly, although I was told by a zoologist that yes, you could, easily. He didn’t tell me how.
I am not a zoologist, but I am an equiphile and have owned horses in the past. I can tell the difference between a zebra and a horse very easily, simply by looking at them. You couldn’t, for example, paint stripes on a horse and tell me it was a zebra (and various TV shows have tried), or Photoshop out the stripes on a zebra and tell me it was a horse.
For example, the angles of shoulder and hip are different, the way the neck meets the back is different, but the simplest way to tell at a glance is to look at the ears and tail. A zebra has large ears with rounded tips. A horse has smaller, pointed ears. The zebra’s tail is ropy, with a tuft on the end of it, where a horse’s tail looks like long strands of hair.
Now, if you painted stripes on a large donkey, that would look more like a zebra. Not the same, but closer.
I know this doesn’t really answer the OP, but there are people far more qualified than I to explain the physiological differences. I’m just saying you couldn’t fool anyone who knew anything about horses with just a color change.
Mitochondrial DNA evidence (link goes to .pdf document) indicates that the various Equus species diverged from a common ancestor ~3.9 million years ago. The common ancestor to the zebra clade (which includes E. burchelli, E. grevyi, and E. zebra [the quagga is considered to be a variant of E. burchelli - its mDNA differs from E. burchelli by but one base pair]) looks to have appeared at about 2.8 mya. The domestic horse stock, then, appears to be only slightly older than the zebra, so differences are likely to be slight.
I would suspect that morphological differences between horses and zebras might be spelled out a bit more in D. K. Bennett’s 1980 paper: Bennett, D. K. 1980. Stripes do not a zebra make, Part I: A cladistic analysis of Equus. Syst. Zool. 29 (3): 272-287. I haven’t been able to find an online copy of it, though.
Concur with Wintermute; zebras are a lot more like asses in build than ponies even the mane is like that of an ass; short wiry tufts.
OK, I’m getting pissed. Not at you guys, but at Snopes. They must have the same crap search engine that some sites have that don’t let you use words under three letters (I wonder what other sites do that?).
Anyway, Mr. Ed, from the 60’s TV show was a zebra. Apparantly, it was trained to do the right things on command.
Zebras are smaller than the typical domestic horse. The man who played Wilbur was only 5’4", and they made the stable set smaller.
I don’t know what Snopes would want to tell you, but this is not a zebra.
Mr. Ed was a palomino gelding named “Bamboo Forester”. He was not a zebra.

Gah! Now that damn theme song is running through my head double-time.

Err…Bamboo Harvester, not forester - everton’s link has it.

I’ve read that Mr. Ed thing too! Where did that start?
This website claims that Mr. Ed was a zebra on the show (for the first few episodes), and a horse in publicity stills. That doesn’t make much sense, but it’s what they claim. It also says (see below) that snopes says Mr. Ed wasn’t a zebra, when in fact they do.
You may be correct. However, I am still looking for that site that said he was a zebra. Maybe it was another urban legend site.
That site may be totally full of sh-t. But I will link it when (if) I find it again.
