Humans accidentally created what once helped the dinosaurs come into existence?

Harvard researchers have found the phenomenon that killed 86% of Earth's creatures and created the fearsome dinosaurs, pterosaurs, scorpions. to take its place. That's what surrounds humanity as well.

The research team from the Department of Biology and Evolutionary Biology and the Museum of Comparative Zoology at Harvard University - USA used contrasting models between the evolutionary history of species on Earth and climate evolution. through each period, thereby leading to the above bold hypothesis.

The article published in the journal Science Advances claims that the first individuals of the dinosaur family were born from a series of phenomena that humanity today hears about every day and is also something we are creating ourselves: Climate change and global warming.

Dinosaurs were born possibly thanks to climate change caused by global warming

Citing research, SciTech Daily reports that scientists have focused on the Permian-Triassic climate crisis, which occurred from the mid-Permian (Nermian) to the mid-Triass (Triassic) period. 265-230 million years ago.

This period marked two major mass extinctions, the first in 261 million years ago, the second in 252 million years ago. These events eliminated 86% of the organisms that had existed in the mid-European period.

There is a connection that appears: The Tam Diep period is known as the first "reconstruction" period, so the dinosaur family later developed into many dinosaurs on the ground, the "flying dinosaur" version - ie. pterosaur - in the sky, the dragons, mermaids, and dragons are in the ocean.

The research team confirmed that it was the seemingly deadly Permian-Triass event that triggered the birth of these monsters, or more specifically, a period before and after this period, forming 60 million years of successive transformations. Climate change due to global warming surrounds the planet.

The increase in global temperature has been revealed in the geological record, accompanied by interesting changes in the fossil record, because it seems that the evolutionary response of reptiles is extremely sensitive to climate.

The rate of adaptive anatomical change started to increase from the beginning of the Second Diep (about 294 million years ago), at the same time as the beginning of the climate change chain. From 261-235 million years ago, global warming increased dramatically from a large volcanic eruption, forming the hottest period in Earth's history and also the most intense period of reptile evolution. .

"Some groups change very quickly and a few even faster, but almost all reptiles are evolving faster than before," said lead author Tiago R. Simoes.

Since then, the world dominated by mammals, with few reptiles of the Nhi Diep period began to be replaced by the reptile world of the Tam Diep period, with many diverse species, including the dinosaur family that existed. strong throughout the Jurassic, later Cretaceous, until it was wiped out by an asteroid.

When large reptiles were born, they continued to respond to climate change by migrating to temperate regions or entering the aquatic world to make it easier to live. Thanks to that, this monster family has become increasingly powerful, distributed around the world with an extremely diverse fossil record left.
