Directional selection is basically a part of natural selection. It only occurs when the environment changes and nature itself would select those who are well adapted to the changed environment. However, we are now able to change the enviroment or counteract any selection pressure that has been exerted on us. So will this prevent us from evolving or just stabilising the way we are now?

How would you best describe Darwin’s theory of evolution by natural selection to someone who was not familiar with the subject? Be as clear and accurate as possible. What scientific evidence best supports evolution by natural selection?

For instance, I'm thinking of becoming a Botanist. The more I read it seems you can get Botany jobs with just a Bio degree though. So I'm thinking would it make more sense to just get a Bio degree to widen my options and then maybe get a Masters in Botany if thats what I want to do?

What do you think will happen to the human body if exposed to higher gravity that to that of earth? Like if I were to be exposed to 0.5g(gradually increased as I progress) for a long period of time, and then came back to earth. Will I have gained super human strength? Or will the human body fail to adapt?

What are your thoughts?
