Answer to Question #297244 in Evolution for Rookie

Question

Natural selection allows certain species to survive. The organisms that survive are those best adapted to their environment. Does natural selection make organisms more complex and perfect?

Answer 1

Yeah that's right; Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. ... Natural selection, however, states that even the most complex organisms occur by totally natural processes.
