Sections 2.1 - 2.5 summarize evidence for Evolution. Some evidence had been available to Darwin and his contemporaries, but the majority of the evidence came later, in the 20th century. For example, Darwin was aware of the following: Answer Vestigial structures Geological evidence for mass extinctions Succession in the fossil record Structural and developmental homologies The evidence from biogeography, based on occurrence of closely related species in groups of islands (such as the Galapago...
