Why did dinosaurs not re-evolve after their extinction?
Evolution is dependent on the pre-conditions and the current pressures on life. After the extinction of the dinosaurs, both were changed. A number of animals survived (including our mammal ancestors), and all of those were competing for the same niches the dinosaurs had filled.
The Short Answer
Evolution is dependent on the pre-conditions and the current pressures on life. After the extinction of the dinosaurs, both were changed. A number of animals survived (including our mammal ancestors), and all of those were competing for the same niches the dinosaurs had filled. The world was also a different place, undergoing climate changes, atmosphere changes, etc. Its probably always more likely that evolution will chance onto a new path, rather than repeating an old one, because the number of possible solutions is nearly infinite.
