Humans won’t survive next mass extinction – scientists http://b4in.org/rRsE
Despite populating vast swaths of the planet, and appropriating large amounts natural resources in order to survive, human beings are no more likely to survive a mass extinction event than rare or endangered species, scientists say.
A team from the University of Leeds examining the effects of mass extinctions found that widespread species, like humans, are just as likely to become extinct as less populous ones.
This contrasts with regular circumstances, where a populous species is more likely to survive than a rare or endangered one.
The team of scientists examined the fossil records of vertebrates from the Triassic and Jurassic periods – 252 to 145 million years ago. During this period a mass extinction thought to have been caused by a volcanic eruption wiped out almost 80 percent of all living species and gave rise to the dinosaurs.
Scientists Alex Dunhill and Matthew Wills from the university looked at the distribution of species and the ways they changed during the time periods. They then compared their results with the changes in overall biodiversity and gathered information on the extinction risk of species.
They found that the extinction of many groups of crocodile-like animals led to the rise of the dinosaurs.
