From what Ive heard latley about the progression of man, it seems we just arent as perfect as we think.

We always get diseases and have body problems.
Our claws are a bit crap.
Our teeth arent even sharp
We dont have any fur.
We cant fly unless we have enough money to buy tickets
Our babies couldnt survive a day without us.
Loads of us live on welfare.
Were always predicting doom and gloom for our species

I could go on!
