Small differences between parents and offspring can accumulate in successive generations so that descendants are very different from their ancestors. Individual organisms born with certain traits are more likely to survive and have offspring than individuals born without those traits.

More recently deposited rock layers are more likely to contain fossils resembling existing species.
