"Gene expression may change in response to physical signals from the environment, interactions between species, and signals within an organism."
So can one of you evolutionists please tell me why I should believe that your theory is not full of crap?
If people of particular races look differently -- and this certainly includes all facial and other physical appearances -- how can Science even begin to create a human phylogenetic tree if traits are modified by the enviornment, not dictated by randomly mutating genes?
Scientists love to dig up skulls, line them up, and then proclaim "evolution" based on their appearance. How is it that this theory is not a complete and total joke?
