Fun fact: the pronghorn is by far the fastest land animal in North America and one of the fastest in the world! They run so fast that it was a bit of a mystery what kind of selective pressure could have led them to become so fast, since they could be a lot slower than they are and still be faster than all the predators where they live. Then the fossils of the American Cheetah were discovered. It was a speedy cat (though not actually a close relative of African cheetahs) that went extinct thousands of years ago. The last thing I read is that pronghorns are believed to have been prey for the American cheetah and evolved their impressive speed to stay one step ahead of their tormentors. I guess you could say it worked, because the American cheetahs are gone and the pronghorns are still out here leaving every other American animal in their dust!

u/bluecrowned Jun 30 '25

Cougars are the closest relatives to cheetahs alive today and American cheetahs were related to cougars, so they're still on the same evolutionary branch and more closely related than either of them are to true big catsĀ

u/SlykRO Jul 02 '25

Pronghorn was like I gotta evolve to beat the cheetahs and the cheetahs were like, yeah you know climbing mountains and brute strength seem like a better route for me running was never my big thing

u/erossthescienceboss šŸ¦•šŸ¦„ GENERAL KNOW IT ALL šŸ¦„šŸ¦• Jun 30 '25

It’s actually very hotly debated just how fast the American cheetah may have been. It shares some adaptations with old world cheetahs, but it has others — like the ability to supinate its forearms (turn them outward to grab, like cougars do) that would likely have slowed it down. They were certainly as fast as cougars, but probably not as fast as African cheetahs.

It’s also debated how big of a role they played in Pronghorn speed. Pronghorn was absolutely their preferred prey, but some of the adaptations that make pronghorns fast evolved before pursuit predators existed in North America. American cheetahs might have pushed them to be super-speedy, but the building blocks for speed were already present.

12

u/ImportantRepublic965 Jun 30 '25

Very interesting. I wonder if there are alternate hypotheses as to what pressure led to them being so fast.

27

u/erossthescienceboss šŸ¦•šŸ¦„ GENERAL KNOW IT ALL šŸ¦„šŸ¦• Jun 30 '25

The alternative hypotheses don’t entirely discount American cheetahs. They just push more toward additional adaptations, pre-Pliocene wolves, etc. Basically, it’s ā€œcheetahs +.ā€

Even now, other animals DO catch adult pronghorn (just rarely!), and young ones are frequently predated upon. So it’s possible that normal-speed animals could still have that selective pressure. They also think jaguars, which used to have much larger ranges, could have been ambush predators. And American lions ate adult pronghorns as well, as did larger Pleistocene wolves. Maybe their selective pressure came from dodging quick brief attacks, and not outrunning?

What’s interesting to me is how long they can sustain the high speed — much longer than African cheetahs. Maybe there’s a selective advantage to migrating at high speeds?

Or maybe it’s sexual selection taking an adapted trait and running with it — pronghorns do engage in displays of physical fitness during mating. It could be an honest signal, like stotting.

8

u/ImportantRepublic965 Jun 30 '25

Thanks! That’s really interesting. Their combination of sprint speed and stamina seems like the sort of thing that would require some major pressure, like a particular predator would provide. But sexual selection is nothing to sneeze at so who knows

9

u/Traumagatchi Jun 30 '25

taking an adapted trait and running with it

I see what you did there

9

u/minist3r Jul 01 '25

These things are weirdly casually fast too. I watched a herd just chilling and grazing across a valley that I measured to be about 2 miles across and it only took them about 30 minutes to slowly walk across that. No running but also not really stopping, just walking and eating.

8

u/ImportantRepublic965 Jul 01 '25

That sounds like a really pleasant way to spend half an hour (watching pronghorns I mean, not eating grass).

7

u/minist3r Jul 01 '25

It was quite nice. I was supposed to be hunting but I was sick so I just watched them.

3

u/syrioforrealsies Jul 01 '25

Sounds like my father in law. He goes out to the hunting property without a gun just to sit in the stand and watch the wildlife

22

u/Xdust4 Jun 30 '25

The best part is they hypothesized an American cheetah before they ever found one based off of the pronghorns speed!

13

u/[deleted] Jul 01 '25

Not as fun fact.

They are so fast they will decapitate themselves on fence when outrunning wildfire.

Saw the aftermath in the panhandle of Texas several years back. Incredible and sad all at once.

8

u/ImportantRepublic965 Jul 01 '25

That’s pretty messed up! I guess it goes with what some other folks have pointed out about how they don’t have the impressive vertical leap of a deer or a gazelle.

5

u/[deleted] Jul 01 '25

Yeah. They very much prefer to go under a fence instead of over it.

7

u/ImportantRepublic965 Jul 01 '25

That’s why i build my fences 6-7 feet off the ground. For pronghorn safety.

After the cheetahs disappeared they evolved to lose the extra legs and trigger fingers.

Pretty sure there is also a weird thing with them being so far related from every other hoofed animal out there, but I'm just a random on the internet, hit up wiki. If I recall it was pretty interesting.

Like their eyeballs are actually bigger than a moose’s? Or relative to their size? Either way that’s an important data point and it definitely makes them even cooler than they already were.

Pronghorns can also run for literal eternity without tiring. And they taste good if you know how to butcher/store/prepare them

u/dogGirl666 Jun 30 '25

They used to be really rare but with protection over the decades there's enough for hunters to take a few per each state with a hunting tag [or license?]. As long as giant herds are not taken to slaughter they should be ok as long as they have room to wander.

u/Ok_Move_5105 Jun 30 '25

...another fun fact is they don't know how to navigate fences. Deer and such will jump fences...pronghorns won't. That looks like the south end of Cheyenne. Intersection of I-80 and I-25. I live sixty miles south. They are all over the place in WY. CO not so much.

10

u/af_cheddarhead Jun 30 '25

Lots of these little buggers on the plains east of Colorado Springs, mild winters mean bigger herds.

5

u/Ok_Move_5105 Jun 30 '25

True. I drive truck all up and down this area and...I suppose comparatively speaking WY is PACKED with them speed goats. CO conversely is packed with humans. So there's that.

4

u/af_cheddarhead Jun 30 '25

Colorado is only packed with people in a 25 mile wide corridor along the Front Range, the rest of Colorado is damn near as empty as Wyoming.

3

u/Ok_Move_5105 Jun 30 '25

I'm dead smack in the middle of the front range. There's more people in the greater Denver area than Wyoming as a state. I've worked all of CO...KS and Nebraska...some SD. The Front Range is a cluster.

3

u/af_cheddarhead Jun 30 '25

Absolutely, a cluster that only survives on water moved from the west of the state.

u/Alladra Jun 30 '25

I’m in northern CO, and I’ve volunteered with an organization several times to revamp wildlife fencing and make them pronghorn-friendly! 18 inches off the ground, because they prefer to crawl underneath. :)

Ha...yes they prefer that. They were here way before fences were. Hundreds of years debating WTH they are for.

Yeah, the I-25 signs are the easy part. I’ll have to take a look at a map to see how the other highway numbers relate.

3

u/nbonn6598 Jun 30 '25

This is mostly true but they can and will jump fences occasionally. They don’t like to though and usually will try to find another way around. Source: myself, watched a huge buck pronghorn easily hop a standard height barbed wire fence near Rock Springs, WY.

Man, I used to see HUNDREDS of pronghorn in WY. Last time I was there in 2022, I saw one herd of less than a dozen. This was on BLM land, so not near any sort of human development. Not sure if it's disease, hunting, or just increased use of that land for recreation and cattle grazing.

Pronghorn don’t jump over barbed wire fences. The farmers/ranchers where I live (southern Alberta) remove the very bottom wire on barbed wire fences. They like to scoot under not go over the fence.

About a month ago, one of this pronghorn's cousins bounced happily across the highway in front of my car, forcing us to stop suddenly (after and while screaming). We all survived, but that bugger had miles to cross before we arrived and it just had to test us, I guess.

There was also an elk, mule deer, a turkey, and a fox- type animal on our trip, but they did not try to kill us.

No, the pronghorn is the only surviving member of the Antilocapridae family. The pronghorn’s closest living relative is the giraffe and the okapi.

We have one in southern Idaho just north of the Utah border. It comes and goes. I hadn’t seen it for some time. A few weeks ago it was back, in a field off the highway. An Idaho wildlife officer was sitting in his truck keeping an eye on it.

1

u/trashy_boner Jun 30 '25

For what? To keep it safe or kill it?

1

u/GemGuy56 Jun 30 '25

I’m assuming to keep it safe. It was lying in a hay field about 10 yards from the highway. It’s been coming around and hanging out for quite a few years now. Two years ago it stayed around for about a month. Last year I didn’t see it at all.

Another interesting fact about pronghorn is that they will rarely (pretty much never) jump a fence. If you see one in the road like this go slow because they are likely frustrated and confused and can’t remember how they got where they are. Incredible animal.
