Several fascinating theories concerning the evolution of living things have been told. According to one, a massive asteroid crashed into Earth’s atmosphere 66 million years ago, wiping out non-avian dinosaurs.
Surviving species like mammals, frogs, and reptiles spread, diversified, and evolved into many of the species we know today. However, new research has highlighted what snakes were doing during the Cretaceous-Paleogene (K-Pg) mass extinction.
Only a few of the surviving asteroid snakes appear to have evolved into all of today’s serpentine species. There has been a debate among scientists about the impact of mass extinction on reptiles like lizards and snakes. Initially it was assumed that they suffered only minor losses, but evidence of a high rate of squamate extinctions around the K-Pg border in North America has been uncovered, according to the team who wrote about it.
Because there are few ancient snake fossils, evolutionary genetic research of snakes is based on a small number of characteristics. According to researchers, this can lead to skewed patterns that do not reflect their true genetic history. Researchers at the University of Bath transformed the evolutionary genetic study of snakes by merging several modeling methodologies using genetic data and sampling of fossils in different time periods to provide a comprehensive view of modern snakes by then and today. hui.
Because the competitors (including other snake species) became extinct, the survivors were free to roam and resettle in new environments and habitats.
There were Cretaceous snakes before this period because their vertebrae were different. However, after the destruction of these snakes, contemporary snakes in all their magnificent forms and forms began to emerge.
After the giant 10 kilometer (6.2 mile) asteroid ravaged Earth, vipers and cobras, tree and sea snakes, boas and pythons all appeared. The team concluded: “Our results help to corroborate the fundamental role of K-Pg mass extinction in the formation of the biodiversity of vertebrates occupying our planet today.”
The extinction of many vertebrate groups during the Cretaceous-Paleogene (K-Pg) period resulted in a rapid global expansion of surviving mammals, birds and frogs. “This seems to be a general feature of evolution – these are the periods immediately after major extinctions where we see evolution at its most wildly experimental and innovative,” the team added.
