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. Some scientists actually think within the next couple centuries due to arctic sea ice pretty much disappearing polar bears will either go extinct, or interbreed with grizzlies so much that there isn’t a “pure” polar bear left. Most likely a mix of both.
Close enough that we probably helped bred them out of existence. Neanderthal genetic markers show up with some regularity in certain modern human populations.
Edit to add: While humans didn’t breed them out of existence, we certainly did intermix with them. And that does help to maintain their existence yet today.
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.

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.
Hey, Mac! You still have that Halloween costume?
So are Neanderthals and homo sapiens the same species then?

Biologists wouldn’t say they’re the same species, because biologists are aware of interspecies hybrids and the species problem.
Golar bears and Pizzley bears
She has a type.
She likes them brown boys
fun fact: polar bears have black skin.
Scary… Polar bears comming to my house! Slightly larger whiter Grizzlys still a problem.

In the near future, Polar Bears as a separate species will likely disappear, and we’ll have all hybrids.
