The extinction of the dinosaurs was most probably caused by an asteroid hitting the Earth - but what would have happened if the giant space rock had missed? For a long time it was thought that dinosaurs were a lumbering, cold-blooded extinction just waiting to happen. Even the word dinosaur has come to mean something that has outlived its time. The scientific argument was that as cold-blooded creatures, dinosaurs would not have stood a chance of surviving an ice age. "According to the first imaginings of palaeontologists and the general public about dinosaurs, we thought of them as reptiles," says Kristi Curry-Rogers, from the Science Museum of Minnesota. "'Reptile' is a word which comes with a lot of other connotations, like cold-blooded, slow-moving, sprawling, scaly skins, kind of stupid." But more recent discoveries, such as dinosaur fossils in both polar regions, reveal that these animals were far more adaptable than previously thought. ~~~~~~~~~~~~~~~~~~~~ [green] This is an interesting theory. Especially since with the advance ment of technology, the study of Dinosaurs is revealing new breeds and making us think twice about what they were really like.

Dinosaurs are supposed to be the ancestors of modern birds and all birds are warm blooded so that must mean that some of the dinosaurs were warm not cold blooded. Perhaps if the asteroid had missed earth the dinosaur would have developed in to a humanoid of sorts.... what a thought, safe to say we would never have arisen.
