Certain chemicals, such as cytochrome C, are found within cells of all living organisms. The biochemical
structure of cytochrome C in ground finches and in tree finches is very similar. This suggests that tree
finches and ground finches have
(1) identical DNA (3) evolved at the same time
(2) a common ancestor (4) the same nesting site
