10.1 Darwin and the Theory of Evolution
... Darwin’s theory of evolution actually contains two major ideas: a. One idea is that evolution occurs. In other words, organisms change over time. Life on Earth has changed as descendants diverged from common ancestors in the past. b. The other idea is that evolution occurs by natural selection. Natu ...
