From the games we can see that the Kilrathi are quite furry. We also know that their world is hot, dry & the opposite of humid. So I was wondering how they evolved all that fur. I mean wouldn't they have died from heat stroke or something? What do you think?
True but considering that Kilrah never went through an Ice Age there would never have been any need to evolve fur in the first place.
Besides how do we know the Kilrathi need water? On the losing thread in WC3 Thrakhath mentions that Earth is too watery for his tastes - giving the impression that some Kilrathi dislike water or humidity.
They would probably treat Earth cats and dogs as a delicacy.
Theres no reason to think that there wouldn't be water on Kilrah. less then on earth, obviously, but there would be some. They've lived on our ships and we've been on theirs, so they apparently live in about the same temperature ranges we do. i think you're overestimating the "hot" description
Fur isn't used just to keep heat in. There are many cases when fur is used to keep heat OUT.
Even if the planet were hot enough to make water steam away (which I don't think it is). the air pressure could be higher, this would raise the temperature at which water changes from a liquid to a gas.
I think that the evolution on Kilrah favoured predator (i.e. cat) development because there were no big forrests where other species could seek shelter and hide from them.
But on the other hand there had to be a vast number of prey for the cats to feed on. Where did they go? Or did the Kilrathi learn that quick to tame wild animals and breed them for feeding? Must have been a pretty fast evolution.
No one will hear your cry of death in the void of space
I'm guessing they had a much smaller population than earth did too. Predatory animals need a lot of territory, and theres usually relatively few of them around. Once they really got into war, the birthrate probably went way up, but the overall population stayed about the same. once they all started working together as a race (for the most part) that death due to war rate would be way down, which would explain why they have a definite need to expand to other systems. So they're not all bad, they just need more space.
