Fact of the Day: Land Dolphin

While most people know dolphins (and whales) are mammals, they don't realize they evolved from creatures who once lived on land. One of the biggest clues to the origins of dolphins and whales is in their anatomy. Underneath their flippers are finger bones not terribly different from human's. Even the largest whales have bones that were obviously inherited from a creature that had hind legs.

Nonsense! The Bible says the world is only 6000 years old and it would take millions of years for whales and dolphins to grow legs and leave the oceans, and then return to the oceans and lose those arms and legs. Just kidding--the world is much older than 6000 years, and of course what you say is true.

Who knew I had something in common with a Dolphin. Although, I did hear they rape up to 13 people a year...There are even bumper stickers around that says it!

Every time I read that, I always think of primeval dolphins taking a look around and saying, "No WAY I'm staying out here."
