What would have happened if the dinosaurs had not disappeared?

About 66 million years ago, a gigantic Meteor reached the area that corresponds to the Yucatan Peninsula in Mexico and made up the Chicxulub crateer. If this event had not happened, the future of the world and humanity may be completely different from what we know today. Finally, What would happen if dinosaurs had not disappeared in this case?

The effect of the meteor was so strong that it formed a crater of about 180 kilometers, marked the end of the Cretaceous period and the beginning of the Paleogen.

Many dinosaur species have been extinguished almost immediately, but the results of this event triggered atmospheric changes that contributed to the destruction of other life forms. In total, scientists estimate that about 75% of the types of time disappeared.

During the effect, the explosion initiated a large amount of dust in the atmosphere that darkened the sky. With the reduction of sunlight, many plants began to die because they could not perform photosynthesis.

Since they were the basis of the diet of several dinosaurs, the destruction of the vegetation triggered a collapse in the food chain and contributed to mass extinction. This was the fifth major destruction event in the history of the world, a very rare phenomenon It usually occurs at intervals of 100 million to 500 million years.

Although it was a disaster for dinosaurs, this event was very important for mammals and consequently the evolution of people.

It is noteworthy that many birds survive because they are already a group of dinosaurs adapted to different environments. Therefore, it is common to hear that modern birds, including chickens, are the closest relatives of dinosaurs.

“For those who collect fossils from the latest dinosaurs, it is possible to clearly see that dinosaurs have a great variety and abundance all over the world. For me, the dinosaurs are strong, successful, still at the top when they hit the asteroid soil, Steve Brusatte Edinburgh University Paleontology Professor, Steve Brusatte with a message sent to the site Lifeguard.

Without the destruction of large reptiles, mammals had gained almost no space for millions of years and diversified. What if Meteor had never fallen? Dinosaurs can still dominate the world and our species may not develop – How really happened.

What if the asteroid had not fallen?

Before eliminating 75% of species, dinosaurs dominated Earth for at least 165 million years. Experts believe that they will probably continue to occupy the main ecosystems in the world without a disaster event 66 million years ago.

In this scenario, Mammals may not be developed enough to ensure the emergence of humanity.

For part of the science community, Dinosaurs would still disappear or at least most. Researchers believe that excessive climatic events such as glacial ages can eliminate most of these species.S For the next millions of years.

On the day of dinosaurs died, the documentary published by the BBC in 2017 suggests that if the asteroid does not hit the Earth, most dinosaur would be extinguished by natural climate change.

Scientists in the film show that asteroids would probably fall into the Pacific or Atlantic Ocean if it had arrived a few minutes ago or after. Thus, the water will absorb part of the effect. Nevertheless, disaster results will occur, but some large dinosaur species may have survived.

Paleontologist Mike Benton of the University of Bristol He was still sentenced to disappear because of his glacial ages.

“They were intact to the end of Kretase, but we know that mammals were diversified … [e] Dinosaurs have been decreasing for 40 million years, Bent Benton explains in the documentary.

Do people develop?

Even if the asteroid does not hit the world, many paleontologists believe that all dinosaurs will not survive to the present day. Some species will probably disappear due to global cooling periods. Actually, There is no way to ensure that people develop in this scenario.

Some dinosaurs may be saved from glacier events, especially those with hairy or hot. Under these circumstances, mammals probably dominate the world through adaptations that will resist the cold. However, people may not be among these mammals.

In the message to the site Live sciencePaleontologist and Biology Professor in Paul Sereno University of Chicago says that people will probably never develop. According to him, The world dominated by mammals, as we know today, would not have developed if the asteroid did not hit the world And dinosaurs continue on top of the food chain longer.

Dinosaurs as smart as human beings

In 1982, Paleontologist Dale Russell proposed a mental experiment with an interesting question: Could dinosaurs develop to the point of raise awareness? So, can man be a kind with similar characteristics?

To explore this idea The mental experiment was based on Troodontids, a relatively large brain, a kind of dinosaur with opposing fingers and two -legged posture.

Russell called these creatures “Dinosaurides”, a humanoid species with dinosaur properties. Although it is a curious hypothesis, most scientists think it is not possible to occur.

The destruction of dinosaurs may not be a sudden event; Long before the asteroid reached the world, climate change and maritime level variations have already affected several species. Do you want to know more? Understand how to disappear dinosaur before asteroid falling. Until next time!
