Hear Ye: Another Darwinian Prediction Falsified by Fossils
January 3, 2012
In a classic test of evolutionary “post-diction” (predicting what should be found in the fossil record), scientists made a bold prediction of what insect ears would look like before the evolution of bats. Believing that the presence of bats, a new predator with sonar, would spur the evolution of insect ears, the scientists predicted that earlier insects would have less-developed ears, or none at all. Then they found exceptionally-preserved insect fossils from the Green River formation in Wyoming, and compared the fossil evidence with their prediction. What was found?
Vitamin C Loss Is Not Evolution’s Gain

Evolution predicts gain of function; genetic entropy predicts loss of function. A gene that helps synthesize Vitamin C provides a test between the two views.
Unique Mammal Senses
July 30, 2011
The ability to sense the environment is vital to all living things, and is a key characteristic that separates life from non-life. The senses are not limited to the five we learn as children – sight, hearing, touch, taste, and smell. In the animal kingdom there are more. Some of them repurpose existing organs; some detect other information from the world not detectable with the normal sense organs. In mammals, two very different animals – bats and dolphins – have expanded our understanding of sensation.
Oldest Bat Fossil: Was It Evolving?
February 16, 2008
A bat fossil surpassing the previous record holder for the oldest by 2 million years made the cover of Nature this week.1 The news media immediately began saying that it provided insight into evolution. The BBC News announced “Bat fossil solves evolution poser.” National Geographic called it the icing on the cake, and said that […]
