Why do humans train dogs to pull a sled? Why did some humans make other humans slaves? Why do some humans hire other humans to clean their toilets? Is it about durability or is it about avoiding hard/disagreable work? I do not think you can use this argument to say humans are less durable, just that we tend to be lazy.

As for the issue of training, put aside ideas of modern humanity and go back 4000 years. Humans then tended to use their bodies a lot more than we do today. The average human then could be more fairly compared to an average wild animal. We did not die in the wild and our durability had something to do with it. Our brains are great, but they need the body to execute their plans. In Dominions terms (vain effort to stay on topic) a nation with 100 Sages and no infantry will be quickly over run by 100 slingers... You need both body and brains. If we are as weak as some suggest, how did we ever survive this long?
