Series: Behe, Lenski and the “Edge” of Evolution (5 entries)
In this series, we reexamine the claim made by Intelligent Design proponent Michael Behe to have found a limit to “Darwinian” evolution in light of recent results from the laboratory of Richard Lenski.
Speciation and Incomplete Lineage Sorting

The Cambrian “Explosion”, Part 2
The procedure of classifying organisms is called taxonomy, and the general name for individual groups is “taxa.” Significantly, the first question that needs to be addressed is -- What is a phylum?
