The short-faced bears turned out to be remarkably adaptable, undergoing radical changes to meet the demands of two changing continents. And yet, for reasons we don’t quite understand, their adaptability wasn’t enough to keep them from going extinct.

    I highly doubt they were talking about short faced bears; oral tradition doesn't go back that far. The tales of "Stiff Legged Bears" in north eastern tribes may have been about polar bears following walrus groups back when they used to be found in New England waters.

    Yeah it is mind boggling how recently grasses appeared. And grasslands are far far younger still. If memory serves I think the first fossil evidence of grass was even from a sauropod coprolite. Additionally the grass showed the hallmarks of a few separate lineages indicating they must have been far older :D Though I do have to wonder whether there might be something similar to what happened with angiosperms in general where the oldest fossil evidence at the time suggested they were super recent based of a primitive fossil from the middle to late Jurassic. Then some excellent fossil discoveries in the last few years helped push the date of the first appearance of angiosperms 50 million years back into the early Jurassic. Interestingly enough while 50 million years older than the previous earliest fossil flower the new record holder looks to be significantly more "advanced" than the previous oldest flower (The one PBS Eons mentioned back in their angiosperm video) which suggests Angiosperms likely originated sometime in the Triassic and that the previous flower may have already been a living fossil when it was fossilized lol. On that note perhaps they ought to redo the earliest flower video? I had felt they were unusually conservative in that episode opting to disregard the molecular clock studies as well as the fossil pollen and coprolite evidence.

The stereotype that mammals were just helpless dinosaur fodder with no significant evolution until the extinction of non-avian dinosaurs has been shattered by the discovery of species like Repanomamus and Castoracauda. And the genetic coelescense of many modern mammal orders appears to occur before 65 millions ago which means mammals were already diversifying into their current forms even in the midst of dinosaurs.

    Arctotherium extinction coincides with the disappearance of savanna-like grasslands and the rebirth of the Amazon rainforest. Big animals have trouble competing in closed biomes, so maybe that's why they adapted to smaller sizes.

    It just occurred to me that there may be another reason for modern bears (or least for some of them) to be smaller than the short faced bears of the past: trees. The Americas used to be much grassier, but with the forest showing up more after the glaciers moved thru, there would be significant advantages to being small enough to climb trees to grab whatever might be hiding in them. Grizzlies are too big to get much in them as adults, but still CAN climb them. Polar Bears have no direct excuse in that regard, but as members of the same genus, they still could have inherited the slightly smaller size for climbing reasons

    Burn Angel 😖 Sigh! Please ask a firearms specialist about the difference between a rifle and a bow and arrow. In particular, the rate of fire each offers. Then claim that they were equally responsible for the slaughter of bison. In passing, also note that the native plains people who hunted these animals with simple weapons did not attempt to eradicate them. That was up to the colonists who aimed to exterminate the indigenous population by starvation. Have you heard of one ‘Buffalo Bill Cody’ and his throngs of hunters posing for a photograph whilst standing beside a huge pile of bison heads?

    The short faced Bear reminds me of the short faced Kangaroo from Australia, Procoptodon, it had a short face because it browsed on food mainly in shrubs and branches above ground unlike modern Kangaroos which graze on the ground and need eyes much higher than their mouth to avoid predators. Maybe the short face Bear had the same adaptation and fed largely above ground?
