Were the Mammals to Be Blamed?

There is this theory that dinosaur had gone extinct because of the mammals. Mammals were more adaptive animals and they had managed to push the dinosaurs out of their place. I even remember some kind of picture showing small mammal eating the eggs of a huge dinosaur. I don’t think this is a serious theory. Dinosaurs must be extremely stupid to allow mammals playing with them. I believe it was a change of the environment that was the cause of dinosaurs’ extinction. This seems to me much more of a logical explanation. You can see in modern time they are interactions between species and highly evolved animals share place to live with other. If you had adapted to the environment, like sharks for instance, you never let others take your place. Sharks are really perfect example how evolution and adaptation are not always hand by hand. Animal with higher evolution is not always a winner in struggle for survival I think. Mammals may have eventually shrunk a little the kingdom of the dinosaurs but to make them extinct - this does not sound serious to me.
