"Natural selection" is the mechanism by which biological complexity and adaptation arises.  It was first proposed by [[Charles Darwin]].  Darwin proposed that, over millions of years, the natural selection of species would result in an organism that was different from the original species.  This process is known as evolution.

Darwin pointed out that organisms with favorable traits are more likely to survive and reproduce than those lacking those traits or possessing unfavorable traits. Over time this mechanism might allow those favorable traits which are inheritable to become more common.
