Snakes are Developing



Scientists are discovering snakes have grown from much more recent ancestors, according to
Snakes today, including almost 4,000 living species, diversified around the time that an extraterrestrial impact wiped out the dinosaurs, and most other species on the planet.

¨According to the study, scientists at the University of Bath and collaborators from Bristol Cambridge and Germany, used fossils and analysed genetic differences between modern snakes to reconstruct their evolution. ¨ They backed these facts up by Tree Hugger, Scientists Daily, and Evening Standards.

Some more facts on how these venomous snakes are alive are: The researchers say the ability of snakes to shelter underground and go for long periods without food helped them survive the destructive effects of the impact. Lead author Dr Catherine Klein, who now works at Friedrich-Alexander-Universitat Erlangen-Nurnberg (FAU) in Germany, said: “It’s remarkable, because not only are they surviving an extinction that wiped out so many other animals, but within a few million years they are innovating, using their habitats in new ways.”

Evidence shows why snakes aren’t extinct. The extinction of their competitors allowed snakes to move into new niches, new habitats, and new continents. The study also suggests that snakes spread across the globe around this time. Although the ancestor of living snakes probably lived somewhere in the Southern Hemisphere, snakes first appear to have spread to Asia after the extinction.
So these facts are some reasons there are many snake types and species of different snakes; some of them are very rare. As well as how there’s a lot of them alive today. The universities are doing a great job of using fossils and analysing them to research different animals.
