    I was just having a discussion with some people and we started talking about genetically modified grizzly bears (I have no idea how we got on the topic). There was some debate over whether larger grizzly bears would run faster due to increased leg length. Has there been research on this? Do larger members of species run faster and if so how much faster?

    Are you more concerned with speed than size? I don't think it would make any difference whether the modification for speed meant the bears became large or not. But if it's size and speed then...

    Assuming size equates with age, I would think it absolutely necessary for a larger parent to outrun smaller young offspring (ie cubs) if only to prevent early mortality. I have seen enough documentaries over the years that suggest predators seek out the old and the young so I'm thinking that's probably got something to do with the speed of the prey. Then again I've heard on the same type of shows that adults of some species kill the offspring of others (i believe grizzlies will do this) so I'm thinking that first they have to catch them. So maybe sex/breeding is also a good reason to be larger and faster.

    So would a genetically modified larger grizzly upset the delicate process of evolution? Is it possible that larger & faster gm older bears that should have died as they aged and slowed down, might become a major competitor and a danger to the species?...idk.

    All that belongs to human understanding, in this deep ignorance and obscurity, is to be skeptical, or at least cautious; and not to admit of any hypothesis, whatsoever; much less, of any which is supported by no appearance of probability...Hume

    Well specifically we were talking about how you could take some genes from lobsters (which do not stop growing) and add them to larger animals. So in a sense you guessed correctly, the larger animals would be older. It was just my hypothesis towards what an environmental extremist group would do if they had the resources to do it. Larger animals would become more of a threat to human populations like lions the size of elephants or even larger grizzly bears who would eventually eat humans because they're too big to get enough food in the wild. I can't imagine how thick a grizzly bear's skin would be if it didn't stop growing, you generally need a .45 kill them now so it would require a ridiculous caliber if they were the size of a house. I guess you could also increase speed and perhaps the strength of their claws with the right know how too.
