Irreducible Complexity Nested Within Irreducible Complexity: The Case of Chromosome Condensation

It is highly implausible that such a wonder of engineering arose by means of an unguided evolutionary process. Read More ›

New Paper Examines How the Complexity of Glycan Structures Points to Intelligent Design

"This is, of course, important in order for a kidney cell to be and function as a kidney cell, a nerve cell to function as a nerve cell, and so forth." Read More ›

When Building Our Case for Intelligent Design, How Should We Think About Prior Probability?

Bayes’s theorem is a tool for modeling our evaluation of evidences to appropriately apportion the confidence in our conclusions to the strength of the evidence. Read More ›

Recurring Design Logic in Gene Regulation

A feature of biology that has struck me over the years is the phenomenon of recurring design logic, across systems that do not appear to be related by descent. Read More ›

The Cell Division Challenge to Eukaryogenesis — And to Evolution

The disparity between the eukaryotic and prokaryotic cell division is very surprising given the standard evolutionary view of gradual, incremental evolution. Read More ›

The Eukaryotic Cell Cycle: An Irreducibly Complex System

Any system that achieves a complex higher-level objective by means of various well-matched interacting components requires foresight to come about. Read More ›

Is Daphnia Evolving at “Lightning Speed”?

If this is a prime example of the transformative power of evolution, the evidence is not at all impressive. Read More ›

New Paper Challenges Evolutionary Account of the Eukaryotic Cell Cycle

This is a subject of long-standing interest to me, and I have published several articles here. Read More ›
