Dinosaurs have successfully evolved over millions of years, adapting to their environment and becoming the dominant animal species on the planet. But why the dinosaurs did not evolve again after have been extinct?
When all non-aviary dinosaurs were exterminated, with them their evolutionary history is gone. The living species are the descendants of animals that survived the extinction eventincluding many mammalian species, which were able to reproduce, evolve and adapt to their new environments.
An extinct species cannot naturally evolve to be exactly as it was before it was decimated – although similar creatures may emerge through an iterative evolution, as happened with the Aldabra carriça.
According to, there are those who have their hopes in Genomic Sequencement to bring animals with Oeo back from the dead.
Scientific capacity and available genomic data are currently far from enough to create an organism as complex as Velociraptor.
Some paleontologists have debated whether the reign of dinosaurs was coming to an end before the impact of the asteroid, possibly as a result of environmental changes. If it were true, it could offer another reason not to have evolved again.
According to a study in 2016, dinosaurs extinctions were already exceeding the number of dinosaur species that were emerging.
However, more recent studies indicate that a Decline in diversity would not inevitably lead to its disappearance and that the chronology of temperature that led to mass extinction It does not support the hypothesis that volcanic eruptions were the culprits.
While some dinosaurs, such as sauropodmay have been declining, others were not only well as could still be evolving todayif it weren’t for the asteroid.
Perhaps the process of evolution had changed its appearance and behavior a little in the 66 million years that followed. Even so, Nicholas R. Longrichpaleontologist and evolutionary biologist at the University of Bath, says that the history of 100 million years of dinosaurs gives few indications that they would have changed a lot without the involvement of.
Although there is little chance of finding a or to cross with a Stegosaurus In the next few times, the World never completely got rid of dinosaurs.
As current birds are descendants of a guipo of dinosaurs called teround. Researchers attribute their survival to their body size, habitat and diet.
