Facts about evolution, natural selection, and adaptive polymorphism
... Evolution is change over generations in the inherited characteristics found in a population or species. Evolution is often a slow and gradual process, but in the 3,500,000,000 years since life began on Earth, there has been plenty of time for it to produce the great diversity of life we see today fr ...
