Light sensitive species - a problem for dinosaur extinction theories
One of the biggest mysteries in earth history is what caused the extinction of the dinosaurs. There are over 100 theories, including the suggestion that dinosaurs suffered from slipped discs, shrinking brains or chronic constipation. The most popular idea is that a meteorite hit the earth and caused dramatic changes in earth’s climate, which led to the demise of the dinosaurs.
However, even though this story is often repeated as fact, many scientists don’t believe it. For instance, in their book The Great Dinosaur Extinction Controversy, two evolutionary scientists explain how the meteorite idea has become a new dogma that has outstripped the evidence. They expose many problems with the theory. For instance, how did some organisms that require daily sunlight inexplicably manage to survive an event that supposedly blacked out the sun and caused 50% of species on earth to go extinct!
So, it appears that even the best evolutionary theory of dinosaur extinction can’t see the light of day!
