Like many plants and animals, the horseshoe crab is a living fossil. Fossilized specimens have been found that are believed to be 300 million years old, and yet are virtually identical to modern varieties.

“believed to be” is the warning sign here.

These findings are consistent with the Bible, which says that God created the horseshoe crab and all the other types of sea creatures on the fifth day of creation only a few thousand years ago.

Being consistent with a fairy tale is not proof of the fairy tale. Then we come to:

Their existence puzzles evolutionists.

No it doesn’t. Not one “evolutionist” has said that he’s puzzled by the existence of horseshoe crabs.

In National Geographic, Biologist Sue Schaller says “You’ve got an animal that predates dinosaurs by 200 million years, and it hasn’t changed much at all. It hasn’t had to evolve.“ [emphasis added]

That’s not puzzlement, that’s an explanation! Evolution isn’t a constant march of gradual change over time. It only occurs under environmental pressure. Horseshoe crabs reached a stable morphology 350 million years ago. Their environment has barely changed, so they’ve barely changed.

It’s really pathetic that people who know nothing about evolution are running around telling people how evolution supposedly works.
