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?

A new study published in The Open Evolution Journal described a paradox that particles-to-people evolution has failed to resolve. Called the "mutation protection paradox," it could be an intractable problem that would leave creation as the only viable origins hypothesis.

Never before had the fossil of a flying insect been discovered in Carboniferous rocks, which are said to be over 300 million years old.

A massive fossilized spider has set a new size record. It looks like today's golden orb-weavers, which are large enough to dine on small birds. This discovery, in conjunction with similar ones, presents problems for evolutionary origins, and also shows how a name choice can be misleading. What did scientists decide to name this fossil, and why?
