darwin was he right!!!

[The worm]

I will make this brief
Evolution (big word to start with) got every ones attention
practically evey animal on this planet has developed to cope with its surroundings(theres a few like ants but were not going there).so why havent humans three main points are
1.why do we walk up right are bodies arent designed for this i know the point about using are hands but monkeys can still do both and i know if a tiger was about too eat ether of us a monkey would be up a tree and long gone.
2.why dont we have a large amount of boby hair how would are ancestors kept the sun of there back or warm, catching animals for fur
(yeh right on day1).
3.Also the size of are brains i know most of us only use a small % but it also creats a huge inblance when were walking.
So why didnt we die out like the dodo's!!!!!!!!!!!!!!!

Answer to all three:
Because those were the mutations that proved advantageous for the environments in which we found ourselves.

There was an excellent program on The Science Channel over the weekend that supplied good solid, logical answers to your quesions you have asked. Although it made some assertions as fact that I would dispute, I highly recommend it. I forget the name. Try and catch it if you can.

Whereas we would just shoot it with a rifle, or kill it with multiple spear thrusts. That way we don't have to leap up a tree every time we see the same tiger.

The reason for that has not been decided. It does afford us a more efficient cooling mechanism through sweating. It may be because we adopted a semi-acquatic lifestyle for a time. (A controversial theory, but one with some interesting consequences. Google aquatic ape.)

We all use all of our brains. Someone has told you the old chestnut about using only 10%. That is nonsense.
We have a pretty good balance system, inherited from our tree climbing ancestors. Is your brain so large it causes you to fall down a lot?

Also, welcome - and why is this in Introductions. It seems a funny way to say hello.

I will make this brief. Yes, Darwin was pretty much right (correct) in everything he wrote, except for some nit-picking details where he admitted he was guessing. Dodos were killed off by beings higher on the food chain (us). The verdict isn't in yet as to whether or not we will survive.
