New research sheds light on the evolutionary “arms race” after the worst extinction event in history

One of the apparent changes that occurred as a result of the Permian-Triassic extinction event was that birds and mammals became warm-blooded animals. 21.06.2022, Sputnik International

New research conducted by Chinese and British researchers is perhaps the most serious known extinction event in history, a new insight into species evolution after the Permian-Trital Extinction Event (also known as Great Dying). Provide. A question that arose about 252 million years ago at the end of Perm’s geological period witnessed the extinction of most of our planet’s life, after which the Triassic revived a vibrant life. Witnessed. After the mass extinction of the Permian-Triassic, Dr Feixiang Wu Beijing of the Vertebrate Paleontology Institute states that “fish, lobsters, gastric sheaths and starfish show a nasty new hunting style.” As Professor Benton states, the aftermath of the “early Triassic” mass extinction. “Overall, land and sea animals were speeding up, using more energy and moving. Faster,” says Benton. “Biologists call this kind of process an” arms race, “which refers to the Cold War. As one side speeds up and the blood warms, the other side must do so. This affects competition between plant eaters and predators. It also refers to the relationship between predators and prey. The faster the predator, the faster the prey will escape. “

New research conducted by Chinese and British researchers is perhaps the most serious known extinction event in history, a new insight into the evolution of species after the Permian-Triassic extinction event (also known as the Great Dying). Provide.

The extinction event of the problem, which occurred about 252 million years ago at the end of the Permian, witnessed the death of most of the life of our planet, but the subsequent Triassic was a vibrant resurrection of life. Witnessed.

“Everything was speeding up,” said Professor Michael Benton of the University of Bristol’s School of Earth Sciences and the lead author of the new study, as quoted by phys.org.

Dr. Feixiang Wu of the Beijing Institute of Vertebrate Paleontology also said that “fish, lobsters, abalone, and starfish show a nasty new hunting style” after the mass extinction of the Triassic-Triassic.

“They were faster, more snappy, and stronger than their ancestors,” he added.

As Professor Benton states, the aftermath of the “early Triassic” mortality has brought about major changes on land as birds and mammals have become apparently warm-blooded.

“Overall, land and sea animals were speeding up, using more energy, and moving faster,” says Benton. “Biologists call this kind of process an” arms race, “which refers to the Cold War. As one side speeds up and the blood warms, the other side must do so. This affects competition between plant eaters and predators. It also refers to the relationship between predators and prey. The faster the predator, the faster the prey will escape. “
