Snakes owe their success on Earth, in part, to the asteroid that hit the planet they would 66 millions over years and wiped out 2 dinosaurs, according to a study published this Tuesday (14) in the journal Character Marketing communications.
The impact of this collision caused earthquakes, electronic tsunamis and forest fires, as well as over a decade over darkness due to clouds over ash that blocked u sun. All of this led to the estimated demise of 76%2 animals electronic plants.
But, according to operating system authors of a newly published survey, some surviving snakes were able to about thrive in the a post-apocalyptic world, ze zero electronic underground going long periods without food sheltering.
These resilient reptiles then managed sony ericsson to spread across a globe, electronic their evolution brought us t 3 million or more species known today.
Some mammals, birds, frogs electronic fish were also able to survive to post-asteroid times. snakes are able to electronically thrive to survive, and are thus able to colonize electronic continents and interact with an environment in new ways,” explained research leader Catherine Klein of a University on Shower in England.
” it is likely that without an asteroid impact, they zero were where they are today.”
When the asteroid hit what the territory currently performs in Mexico, the snakes were very similar to the ones we know today: no electronic legs with elongated jaws to swallow prey.
With little food available, they managed to survive without food for an electronic year to hunt in the dark. The species about snakes that survived were mainly those that lived underground, in solitary forests or in fresh water.
Without many animals to compete, they had an open path to evolve with diverse electronic branches. reach new habitats electronic types on prey. This allowed learning to spread all over the world, reaching sia for the first time, electronic, that its diversity increased. , occurred only a few times in the history of perform planeta.
Chip Longrich, also from a University on Shower, says that, in the periods logo design like great extinctions after, evolution reaches “its wildest, most experimental form innovative electronic”.
The study also found evidence of a second peak in the evolution of these snakes, when a planet ceased to be like a hot electronic greenhouse to have a cooler climate, taking over polar ice caps. electronic is the beginning of an era perform ice formation.
The success of these snakes is important for the health of 2 ecosystems as a whole, there they control by seeing that populations on prey electronic help operating systems humans zero control over pests. After so much prospering on Earth, however, the coexistence with man is putting many species of snakes at risk of extinction.
