Why dinosaurs became extinct

A recent study revealed that the dinosaurs became extinct due to the impact of an asteroid hitting the earth, while those objects at its weakest. Said Steve Brosat, from the University of Edinburgh: "sea levels rose, resulting in volcanic activity to make many of the objects are more vulnerable to extinction." He explained that the dinosaurs may have been to survive if that asteroid hit the earth before this time or after a few million years, describing it as "extremely bad luck." The publication of this assessment in the journal Biolojikal Rivuoz specialized in the life sciences. Brosat said the BBC: "It was a violent storm of events that took place at a time when dinosaurs were at its weakest." The study included 11 of the top dinosaur experts in Britain and the United States and Canada, for the latest research about the extinction of the dinosaurs 66 million years ago to assess. There is evidence that some types of dinosaur had died before the asteroid hits the earth shortly. And the respect of one of the main questions is whether this gradual decline in their numbers would lead to the extinction of these animals, even if the asteroid did not hit the ground. The researchers concluded that, despite the fact that some species have died carnivorous plants in North America, in the period before the asteroid impact, but there is no evidence of decline in the long term. Or are we? Brosat It is believed that if the asteroid hit the Earth earlier what happened several million years ago to worsen environmental pressures, or after a few more millions when dinosaurs may be recovered, perhaps the dinosaurs roamed the earth to this day. He continued: "five million years before the dinosaurs were environmental regulations are much stronger, and they are the most versatile, as it was the base of the food chain more robust and it was difficult to shift a lot of the species." He added: "If the dinosaurs had a few million more years to restore diversity to own the best chance of survival, and dinosaurs lived about 160 million years old, he has a lot of steep drop in diversity, but they are always able to recover." This enabled the demise of the dinosaurs mammals, including species of the existing diversity and evolution. Rum virtual humans with dinosaur Scientists believe that if they survived the dinosaurs may have been able to develop intelligence and stay up to date Brosat explained that if the asteroid did not hit the ground at a time when that happens, we may we live in a world dominated by dinosaurs. He joked: "But we will not be here because the mammals did not have the opportunity to evolve, and we did not have such a dialogue." This idea curious and ask a question about how it would be possible for dinosaurs to evolve. Is that could evolve in the same way the evolution of mammals, to become an advanced objects resembling modern humans? I asked Dr. Brosat: "Is it possible to where I am a dinosaur and dinosaur place to conduct this conversation instead of us?" Stated: "It is possible to do so. With the existence of evolution never say can not, of course there is the possibility that dinosaurs be able to develop the level of intelligence." This is consistent with Professor Simon Conway-Morris, of Cambridge University, but he did not quite go further than Brosat. Advanced intelligent Morris said the BBC: "If there is not a mass extinction, the dinosaurs were not able to stay until the present time." He added that other groups of animals were of the evolution of the level of intelligence and ability to create tools. But other experts participated in the study were less optimistic than Dr. Brosat. They said that despite the reasonableness Brahinh, they believe that it is impossible to say that the dinosaurs were to survive if the asteroid had hit the Earth at another time. Said Richard Butler, of the University of Birmingham: "We can not restart the life bar to see if it was the advent of the asteroid at another time would lead to the mass extinction." Explains Paul Barrett, from the Natural History Museum, the new study reveals that the number of types of dinosaurs were already declining before the collision of Earth asteroid.
