wxtrim, you are brainwashed by evolutionism propaganda. Cool down and know that there is no possibility of evolution. Minor changes need changes both in genes for body traits and brain ones, which govern the function of body traits. Even if a spider got a new gene for body, if it could not got new change for brain function that control the body traits, the traits does not contribute to the survival, so the traits will degenerate.
LMAO... who taught you these things... Show me one creature that has something on their body or a limb or something that is useless! IT has evolved that way due to the environment and the other animals it had to defend itself against. Everything a creature has evolved into it's because it wanted to procreate (ex: the peacock) survive (to hunt/run away: the lion, cheetah) due to that purpose! We, on the other hand must do the same thing, and that is to evolve! Nature is perfect that way!
.....dude you got it all wrong, its just SELECTION it's not about the change of protein molecules etc. "Natural selection is the process by which heritable traits that make it more likely for an organism to survive and successfully reproduce become more common in a population over successive generations."
second owl it was all like e_e
