"It stands to reason that if the history of life forms a tree, with all species originating from a single trunk, then one can find a common origin for every pair of twigs (existing species) by tracing each twig back through its branches until they intersect at the branch they have in common. This node, as we've seen, is their common ancestor." "Why Evolution is True", p7 Quoted on p115 of "Darwin's Doubt" by Stephen Meyer.
