Fun fact: Grizzlies and Polar Bears are the same species according to the Biological Species Concept.
Meaning they interbreed in the wild (somewhat rare), and produce viable offspring that can have babies as well.
We’re actually noticing this happening more and more with climate change. As Grizzly populations move further and further north, they’re encountering polar bears more often and are more likely to mate.
Hey, Mac! You still have that Halloween costume?
The number of confirmed hybrids has since risen to eight, all of them descending from the same female polar bear
She has a type.
Scary… Polar bears comming to my house! Slightly larger whiter Grizzlys still a problem.
Biologists wouldn’t say they’re the same species, because biologists are aware of interspecies hybrids and the species problem.
There are tons and tons and tons of species that can do this. It’s not clear to me what the prevailing species concept is nowadays, if we’re even still following one.
Fun fact: Grizzlies and Polar Bears are the same species according to the Biological Species Concept.
Calling it that gives it too much credit, it is something thought up in the 17th/18th century without any concept of genetics and evolution.
Which might explain why it breaks down almost instantly under any amount of scrutiny.
It’s a category. All lines are arbitrary to a degree and “interbreeds and produces viable offspring” is not terribly arbitrary. You can have arguments around populations which could and would interbreed if they weren’t geographically distinct, you can argue about whether offspring needs to be viable no matter which way around the sexes of the parents are, or how large the percentage of viable offspring needs to be, but in the end, yep it makes sense to have a distinction somewhere around that bunch of criteria.
House cats and European wild cats are considered distinct species not because they’re genetically incompatible, but because they don’t interbreed – too many behavioural differences, and we’re not speaking about culture, here. So even if they could intermingle in theory in practice they don’t, so they stay separate, so they’re different species.
It’s kind of… a behavioural view on the genome? If you have a better idea, field it.
So are Neanderthals and homo sapiens the same species then?
Close enough that we probably bred them out of existence. Neanderthal genetic markers show up with some regularity in certain modern human populations.
Do not – and I really cannot stress this enough – give any of those bears cocaine
Cocaine Bear 2: Land of the Fresh Powder.
Snapping out of your fantasy as you’re being eaten alive is a bad move.
I feel like the other option is a Jacob’s Ladder experience
They may kill SEAL with a slap but how many polar bear slaps does it take to kill members of other special forces?
One
That depends on the bear’s tactical training, if the bear went through bootcamp then it’s one slap, if the bear is also a SEAL then it’s half a slap.
I don’t know…Ask Mr. Owl.
Bear is black, fight back.
Bear is brown, turn around.
Bear is white, say good night.
Also.
Some black bears are brown.
Some brown bears are black.
Good luck everyone.
Polar bears have black skin. Polar bears are black bears.
Bear is white, say good night, and tuck it in and tell it a story. Once the bear has fallen asleep snuggle up to it, so it has a fresh morning snack.
I remember somewhere they were saying you should remove your clothes with a polar bear. The bear will get distracted and start sniffing your clothes.
I think it was a QI episode and then David Mitchell said something like that Polar Bear being happier in the fact that the human would be better to eat this time because it didn’t have a wrapper.
That’s a myth perpetuated by the polar bears, they’re just perverts
I think removing your clothes is just so the bear doesn’t choke on your belt.
This works because polar bears are super horny. Its desire to rend you limb from limb will be replaced bu overwhelming lust. Of course then you’ve got a completely different issue to deal with, but at least you might not die.
Turn around is a bad idea
If it’s brown, lie down
I had heard it as turn around, but lie down makes much more sense.
Oh, I had understood that to mean lay down facedown (with your back to it) since people usually have backpacks while hiking/hunting, and it provides some measure of protection.
Black bears are pretty skittish, so usually acting big & loud is enough to make them jog away, but I’m not sure someone could take them in a fight if the black bear was cornered.
Speaking of which, bears are extremely protective of their cubs, so if you ever see any cubs, running away from them at full speed is probably the best choice.
Bear is Kodiak, you are trespassing and you will be shot.
Also, one of the few animals that will hunt humans for food
Can’t blame them. They’re running out of options.
its revenge, actually.
I bet it gives good hugs :3
Only once
180 seconds (3 minutes) is a hilarious overestimation. Unless you’re counting the time it takes to bleed out.
10 seconds of fighting, 170 seconds of screaming while being ripped apart.
1 swipe from those giant claws will end you in less than 10 seconds.
Or total time it takes to be consumed
Here is a black bear, a grizzly, and a polar bear.
And Marcie.
Fighting bears isn’t that common of an encounter. I’d be more worried about deer and coyotes or even a single cougar than the off chance of encountering a bear. They will definitely fuck you up but it’s not like they are starting their day to be like “Imma go murder a human” in the same way other urban-adjacent animals are—I think they just wanna get that sweet sweet pick-a-nic basket.
dies from turkey assault
180 seconds feels extremely generous tbh
Worked in Yellowstone for a summer.
Spent some time with the rangers. They got all sorts of questions…
Like which handgun caliber would be best to defend oneself from a bear.
Essentially, the ranger broke it down stating there was a weakness in the skull about the size of a bullet that you had to hit directly to have a chance of dropping a bear with a handgun. While its coming at you and pissed/hungry.
So essentially, you’ve just pissed off the bear before it gets it claws on you.
Well placed slugs from shotguns, rifle rounds, and preferably (according to the ranger in question) a tranquilizer to re-home the bear away from people. That being said, the bears are tracked to an extent and bears who show repeated behavior endangering themselves/tourists tend to be exterminated, sadly.
Hand to claw combat? Human is going down.
This is why in the past, when bears were hunted, they were hunted in their dens during hibernation - at the end of spears to keep that hungry bear as far away as possible from your soft easily rent flesh.
What kind of bear is that wearing the sunglasses?
Your survival time would depend on how far apart you and the bear are, how’s fast you can run, and how angry or hungry the bear is.
Tall snow doggos
*first floor windows don’t go nuts guys no way that lad is reaching all the way to the second floor
Motorcycle helmets are purposefully not-hard. Odd comparison.
Why’s the black bear so sad?
is the fear of this bear why we’re so intent in melting the icecaps?
Still rather a bear than a man though, amirite?
Polar bears are very curious animals, so if you back away while slowly undressing they will stop to inspect each piece of clothing, giving you time to get away.
Be good if the other bears were standing up straight too
Where’s that “imma fight a gorilla” guy when you need him?
The bear in the mural does not look tall enough to look in a second story window. Is that a young one?
Are your second story windows at floor height?
Eeeep!

Thats how we made it this far. Some absolute morons charge ahead and get themselves killed, while everyone else shakes their head. With some animals it works, surprisingly. Others we learn to keep away from- until the next moron feels like " hey, lets try that thing again!".

Zoom in on my shirt, the ring around my neck is about the height and width of a gummy bear, or at least close enough to work as an average
