Is There a Scientific Conflict Between the Theory of Darwinian Evolution and the Fossil Record?

Darwin saw evolution as a slow and steady process with species gradually transforming into new species over long time. He thought that the fossil record should provide evidence for his theory. However, the needed evidence proved to be elusive.

A Chemist's Perspective of the Yellowstone Petrified “Forests"

The Yellowstone "fossil forest" has many layers of volcanic ash. Trace element analysis of these layers reveals they derive from about four volcanic sources, and the layers from different sources are interlaced, implying contemporaneous eruptions of the different sources. Published in Origins n. 65.

Pterosaurs of the Triassic: An Update

This post complements an article that was written in 2014. Since then, there have been some interesting developments in the area of Triassic pterosaurs that are worth mentioning, the most important being the recent description by Britt et al.

Is There Biological Evidence of Life's Recent Creation?

During one of my frequent visits to the office of my high school headmaster, his individual tutelage yielded a life lesson that I’ve never forgotten. His exact words were, “You think you’re right!” Of course I thought I was right, wouldn’t anyone who thought they were wrong change their mind and then immediately think they are right? Now that I’m an adult biologist, I still think that I’m right. Inevitably…

Archaeopteryx: Bird or Reptile? Or Not?

Archaeopteryx is arguably the most famous fossil ever discovered. It has a mixture of bird-like and reptile-like traits, and was first reported only two years after Charles Darwin published his book, The Origin of Species. Since then, another eleven Archaeopteryx specimens have been recovered from the limestones near Solnhofen, Germany.
