Some time ago I quoted Francisco Ayala, the well known Christian biologist, as pointing out that thanks to genetics there are now no more gaps or “missing links” in the family tree of life. We can study relationships via genes and no longer depend on the fossils that we are fortunate enough to have preserved down to our time.
An article today on IO9 addresses the same point from a different angle, explaining how genetics allows us to study life as it evolved in the distant past through the genes of organisms alive today.
