It&#x27;s a good point. Dinosaurs were on Earth for a very very long time. We really have no idea how rare it is for life to evolve in such a way as to become highly intelligent.<p>Makes you wonder if Dinosaurs would have evolved to the point of becoming some sort of highly intelligent reptilian species similar to us. That is, if they hadn&#x27;t been destroyed. :D<p>There&#x27;s also species&#x27; such as Parrots and Dolphins that are both considered to be quite intelligent. So maybe intelligence is a fore-gone conclusion and that final step that &quot;snowballs&quot; their intelligence is just another roll of the dice occurrence.
