After a three-week hunt, Philippine locals used cables to capture a huge crocodile from a remote location in the southern Agusan del Sur province.¹ Guinness World Records deemed it the largest captive croc in the world.² Since last September, caretakers have held the one-ton saltwater crocodile at Bunawan Eco-Park. Were giant crocodiles on board Noah's Ark?

Biologists agree that polar bears, brown bears, and black bears all descended from a prototype of the bear kind. Some researchers infer from the biblical record that bears rapidly and recently diversified from a representative bear pair on board Noah's Ark, while those who reject the biblical record derive age information from other sources.

How much time would evolution need in order to make a mouse the size of an elephant?

Since this kind of evolution supposedly occurs too slowly for biologists to observe, one place to look for answers is in the fossil record. But in order to answer this particular research question, a team of evolutionary biologists made some large assumptions.
