However, I'm just going to make a suggestion:
Some of the topics here can be fairly challenging and sometimes a bit of a background in the sciences being discussed can be useful. It is also necessary to be able to reason things out a bit.
I think if you spent just a little bit of time reading up on evolutionary biology at it's most simple and then thought for a short while about the questions you have asked then you would be able to arrive at your own answers.
They only appear challenging to someone who hasn't been introduced to the topic at even the most redementary level.
If you are unable to manage this there may be some individuals patient enough to try to help you but you'll have to be receptive and demonstrate that you are.
