11 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
