I've got a bone to pick with nature, whats the deal with grizzly's being able to run so fast? It seems to defy the laws of physics. Watching one chase down a deer that was obviously built for speed feels like you're watching a cartoon. How is this possible? they can run faster than racehorses for christ's sake. When was it required that they run this fast for starters? They are intelligent opportunists, and seem to be able to find ample food without hunting fast game. Like sure it helps but I always would have thought bears were the kind of animal that would make it through without adapting the ability to run such fast speeds. Like with cheetahs it was absolutely required for survival, their main food source's speed would have increased from being chased and hence cheetahs had to catch up or starve. And then look at all the speed adaptations cheetahs have, bears are on the absolute other end of the scale, but really aren't all that much slower. Cheetahs have long tails that act like rudders to make sharp turns, but tailless bears can turn on a dime at 60 clicks, cheetahs also have special flexible spines and this and that blah blah blah. There is nothing about a grizzly that is designed for speed, its just a side affect or byproduct of god knows what. Plus all the weight gained over the spring and summer and autumn doesn't seem to affect them. I've seen gigantically fat grizzly bears at their absolute peak after gorging themselves for months in preperation for hibernation still run down sleek hooved running machines with ease. How does this all work? Is it just another mystery of nature? I mean seriously look at a racehorse and a grizzly, one has adapted its ass off to be the fastest it can be, the other just sort of be'd a bear but can for some reason kick the others ass at its own specialty. Is this a glitch in the matrix or what?
