Who needs night vision? When evolution means going blind

Becoming eyeless is an adaptation of sorts, no? ScienceDaily (Sep. 15, 2010) – University of Maryland biologists have identified how changes in both behavior and genetics led to the evolution of the Mexican blind cavefish (Astyanax mexicanus) from its sighted, surface-dwelling ancestor. In research published in the August 12, 2010 online edition of the journal […]

Carbon Dioxide Sensors

Did you ever wonder how mosquitoes find you so quickly? Next time you might try not breathing because they are attracted to the carbon dioxide you exhale. And how do insects detect carbon dioxide? Studies have found two different neuron cell proteins (neural receptors) that seem to do the job. And they do the job […]

Responding to Merlin Part IV – A Clear Picture of a Directed Mutation

This is a multi-part post in response to Merlin’s paper, “Evolutionary Chance Mutation: A Defense of the Modern Synthesis’ Consensus View”. See introduction and table of contents. In the last installment, we talked about how Merlin tried to paint a whole range of semi-directed mutations as “evolutionarily random”, and how this falls short when compared […]

George C. Williams

George Williams died September 8th, 2010. An evolutionist, he had insightful things to say about biology’s information problem. Commenting on the “separability of information and matter,” he wrote: “You can speak of galaxies and particles of dust in the same terms because they both have mass and charge and length and width. You can’t do that with […]

Explanations of vertebrate diversity

In 1996, palaeontologist Mike Benton published a fascinating analysis of tetrapod evolutionary data and concluded: “Competitive replacement has probably played a minor role in the history of tetrapods. In an assessment of the origins of 840 families of amphibians, reptiles, birds, and mammals, fewer than 26%, and probably fewer than 13%, were identified as candidate […]
