The dinosaurs disappeared about 66 MILLIONS years ago... that's a long time!
Humans first appear around 300 THOUSANDS of years ago.
As you see, we're not talking about the same scale of time at all, so there was never any encounter between a live dinosaur and a live human, except in the movies, that might be the reason we find them so cool. :-)
No todas las mutaciones conducen a la evolución. Solo las mutaciones hereditarias, que ocurren en los óvulos o los espermatozoides, pueden transmitirse a las generaciones futuras y contribuir potencialmente a la evolución.
