In his recent book How to Build a Dinosaur, evolutionary paleontologist Jack Horner suggested that birds could be genetically engineered backward to take the form of their supposed dinosaur ancestors.¹ He argued that birds arose through the selection of beneficial dinosaur mutants, and if those specific mutations could be identified and reversed in a new generation, then the

Molecular biologist Michael Behe described a system made of several interacting parts, whereby the removal of one part would disrupt the functioning of the whole, as being irreducibly complex. Both creation scientists and intelligent design proponents highlight examples of irreducible complexity in their studies, because they argue against evolutionary hypotheses.

Cambrian rock layers contain fossils that represent almost every modern phylum of animal, plus many that are now extinct. One animal fossil in particular would win the weird prize, if there were one. Paleontologists have been piecing together this strange creature’s body parts, which look as though they were taken from an array of totally different sea animals.

The vast majority of dog breeds have emerged only in the last several centuries as a result of artificial selection. As new breeds are regularly developed, the many potential varieties within the dog kind are revealed. One distinction among breeds is their unique coats. Recent genetics analysis found that a huge range of dog fur textures are specified almost entirely by just three genes.
