When Asteroids Not Abolish Dinosaurs

When Asteroids Not Abolish Dinosaurs - Many people know, the dinosaurs became extinct because a giant asteroid hit Earth. Although there are other factors, what would happen if an asteroid did not wipe out the dinosaurs?

As known to many people, the extinction of the dinosaurs because of the fall of an asteroid about 10 km to the Yucatan Peninsula, Mexico, 65 million years ago. Former event can still be seen up to now, namely 117 km wide crater as deep as 10 km, Chicxulub.

At that time, the asteroid triggered mega-tsunamis, fires all over the planet and make the sun covered with dust from the asteroid that caused a global cooling period that the 'mastermind' death of many plants.

If dinosaurs were not extinct as written Science, today you can still see it. Known, the dinosaur has a dominance in the mainland for long-term, ie over 160 million years.

If this continues, primates such as humans can not be found. According to Damian Nance Professor of Geosciences at Ohio University, mammals are able to evolve alongside dinosaurs, but the evolution of mammals will not be like this time, humans will evolve no bigger than mice.

The researchers estimate, intelligence 'dinosauroid' evolved in humans. It is based on the size of the large human brain that were once only about the size of the bird brain.
