Scuba divers can explore underwater depths firsthand because of specialized equipment that was developed in just the last century. Likewise, solar-powered airplanes currently in development promise to provide fuel-free flying. These inventions open new realms for human exploration, but the arachnid and insect equivalents of their equipment have been on the planet for ages.

Francis Collins and Karl Giberson, prominent participants of the BioLogos Forum, have suggested that Christians should believe in evolution because it has been confirmed by science. They relied on a category of DNA called "pseudogenes" to make this case in their recently published book The Language of Science and Faith: Straight Answers to Genuine Questions.

Human eyes are well-designed to see objects using light transmitted through air, but not through water, because light travels at a different speed through the two media. However, intertidal-dwelling marine mollusks called chitons can see equally well in both environments. How did they acquire this unusual ability?

The world of biology was stunned when ENCODE, a massive consortium of researchers, announced in 2007 that it had found virtually no inactive "junk DNA" in the one percent of the human genome that it intensively studied.
