I find sources that simply refer to lagomorphs and rodents as glires. The clade gliriforms to me would mean glires + something else, although I can’t seem to find what that would be unless it’s the scandentia due to some need to not classify them as archonta (and also ditch euarchontaglires as well). What’s a nerd to do???

In the beginning all the animals looked the same but Frith went round giving them individual characteristics. When he came to El'ahrairah he hid in a hole so that only his back and hindquarters were visible so Frith gave him long legs to run and long ears to hear his many enemies and a cottontail and said that henceforth El'ahrairah's children would dig in the ground to hide from their enemies. El'ahrairah means "prince with a thousand enemies".

As an Aussie vegan I like the idea of shipping our rabbits back to Europe alive. It's been a fantasy of mine for years.

@pptemplar5840 Год назад

well, to be fair, even if you shipped them out as long as you had a few breeding pair the population would just explode again. Aussie having a reputation for everything alive being dangerous, and then being overrun by a small prey mammal going extinct in other parts of the world would probably be funny if you could ignore the damage.

@brianedwards7142 Год назад

@@pptemplar5840 People always say that but our largest "native" land predator is a small dog, sure, dangerous especially in numbers but hardly a tiger or a bear. Crocs and sharks you can avoid by staying out of the water but other parts of the world have those too. A Brown Snake isn't much worse than a cottonmouth and redback spiders share a recent common ancestor with black widows. It's the heat and the dry that'll kill you. Rabbits are sensitive to heat but underground it's the same comfy temperature all the time. As cats and foxes have decimated the small native animals rabbits have replaced them in the diet of the Wedge Tailed Eagle becoming a staple.

@pptemplar5840 Год назад

@@brianedwards7142 Yeah, it's just the public perception combined with island ecosystem, at first I was confused by the idea because "Well, Australia has a lot of snakes." but rabbits are quick and snakes have low metabolism so it would take a TON of snakes to actually keep the rabbit population in check, so maybe an absence of large/medium land predators is enough for rabbits to get out of control. I'm sure birds prey on them but I don't really know much about austrailian birds, only one I can think of off the top of my head is the Budgie and that's clearly not going to help.

Perhaps Multies couldn’t adapt as well to larger mammalian predators or ecological changes? We still don’t really know.

But it is time to keep watch.

@anotherwesley7661 10 месяцев назад

Thank you for making this! I've always been a little miffed by the lack of good scientific material on lagomorphs available; it's quite sad! I suspect that the idea of rabbits being common and ubiquitous has led to them being a little bit ignored as a serious and interesting topic, to the point where really crucial basic information about them is relatively unknown (like the fact that the European rabbit is endangered in its original range, or the fact that North American cottontails are a completely separate species from their burrowing European cousins, etc.). This was such a cool dive into paleo rabbits and their ancestors; it's amazing how those rare South East Asian rabbits look so ancient and basal, like they're living fossils. Sad we don't have capybara-sized island bunnies anymore, but I suppose the capybara itself is a pretty good substitute even if its a rodent. I hope this video finds many people and sparks more in-depth interest, if only selfishly so I can learn more. :) Best wishes and regards from the land of the smallest and very endangered Colombia Basin Pygmy Rabbit! (...poor little guys have really been hit hard lately in recent years because of increased fires).

Just a short amusing/saddening story from my childhood: there was a pen of rabbits in our neighbourhood, seemingly emotionally "neglecting" them (it didn't belong to an obvious owner, if it was attached to a house we would have thought differently). So we broke in and saved a big black rabbit. Then we just dumped the rabbit, kinda, in a little patch of greenery in front of one our buildings. The rabbit stayed there, confused. When we came back a day later, the rabbit was half-eaten. We speculated a weasel or even a fox must have gotten it. So stupid.
