A question about evolution

Hello, I am not a scientist by any means but I hope someone can explain this to me so I can understand.Why is it that certain animals have evolved features for cold weather (such as thick fur) but humans like Eskimos have not? Contrarily, why is it that a people that have been living in a hot climate for many generations (like Africa) developed black skin instead of something more helpful like white or more reflective skin to help cool them off?Just a question, thank you to anyone willing to help me out.

Thank you for the honest response and thanks for not bashing my faith like most atheist have in the past.However, I've been born into a Christian household and raised a Christian. So that "God exists in the back of my head" feeling will never go away I'm sure of it, I will always think someone is watching. And for now I have decided to keep my faith. (I'm sure you all know who Kent hovind is, he has a lot to do with my faith in God)What do most people in the evolutionist community accept as the most "solid proof" for evolution and against creation?Btw I'm a forum noob, what does YEC stand for?

Response to "Theodoric"I am not trying to catch anyone in a "aha!" Or step on anyone's beleifs, I just honestly want some answers to questions I've had over the years. Please keep this a civil debate, I'm new to the forum and I haven't quite heard all the theories and explanations that are going around thank you

Yes, I am looking for a debate. But as far as my question goes it's pretty reasonably been anwered.
I just think that human interaction and dialogue helps me understand better than a Google search. That's the whole reason I joined the forum.
I don't mean to flaunt my beliefs around, but I want to be honest upfront and let everyone know what I believe in beforehand as not to try to sneak up on anyone
Thank you all for your answersEdited by Micah8294, : No reason given.
