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
One consequence of speciation being a population event is that populations have genetic diversity – not all members of the population are genetically identical. For any particular gene, then, a population may have several slightly different forms present within it. These different forms are called alleles.
Evolution and the Origin of Biological Information
In this paper, Venema explores several examples in biology where random mutation and natural selection have indeed led to substantial increases in biological information. The question of how new specified information arises in DNA, far from being an “enigma”, is one of great interest to biologists.
The Human Fossil Record, Part 1. The Nature of Transitional Fossils
It has become an article of faith for those espousing both the young earth creation model and many who hold to the intelligent design model that transitional fossils do not exist and therefore evolution has not taken place.
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?
How can evolution account for the complexity of life on earth today?
A complex biological structure with many interacting parts might appear, at first glance, as if it were originally created in its present form with all its interlocking components fully formed and intact. It doesn’t seem possible that they developed step by step via biological evolution. In Darwin’s Black Box, Michael Behe introduces a term that he and other proponents of Intelligent Design use for this concept: irreducible complexity.
