Evolution is the idea that all living things arose from a single common

ancestor in the distant past and that life continues to diversify today as new species appear. Evolution explains why

we can classify organisms into different groups (because some

organisms are more closely related than others). Evolution explains why

the cells of all organisms use the same kind of biochemical machinery

(because all life shares a common ancestor).* Evolution is both a theory and a fact
