Or, in general, how do we end up with large animals in harsh environments like tundra or desert? I’d naively assume that it’s advantageous to have a smaller body size and lower caloric needs in places where food is scarce. Yet neither camels nor caribou fit in my pocket.
Why aren’t austere environments populated solely by e.g. Jerboa mice?
In: Biology
because they can. enough adaptations and food sources exist to support animals of that size.
if any number of adaptations/evolutions didnt happen, we wouldnt have polar bears……but we did, and they manage to survive…..so theyll stick around
