How to survive apocalyptic mass extinction, according to science


Scientists have discovered that some species survived the "mass extinction" that approached the extinction of life from the face of our planet.

To understand why some creatures survived 252 million years ago, the researchers analyzed the fossils of ancient marine creatures.

This catastrophe killed 96% of the lives in the oceans and 70% of creatures living on land.

"We are interested in understanding why certain species and communities have survived and recovered better than others," says Dr Ashlei Dineen, a museum scientist at the California Inferno Academy of Paleontology.

"For a long time, biology has focused on the number of species that survive extinction, but we have to ask both what they did and how they responded to stress. These insights are important as we push our planet into an increasingly uncertain future. & # 39;

Humanity owes these long survivors a huge debt, because the beasts that survived eventually evolved into all organisms that currently live on Earth.

But we must also understand the processes that helped them to live through the Great Dying, because humanity is currently in the process of causing mass extinction that could prove disastrous as the old cataclysm.

"We also need to learn how – and how well – these species survive, and accordingly concentrate conservation efforts," added Dineen.

"When you consider the mass extinction we are facing today, it is clear that we must take into account all systems before it is too late to correct the course."

The study showed that creatures that had "modern features such as increased mobility, greater metabolism and more diverse feeding habits".

These "hard-core exits" they were stronger and harder, with the fish that became agile, predators became more effective, and even sea invertebrates such as mussels became more defensive.

After the disaster, the sea began to fill the "bigger and more active survivors that are stunningly similar to the inhabitants of our modern oceans."

"Based on the analysis, we learned that in addition to documenting the number of species occurring during ecological recovery, we need to know what they were actually doing – what scientists call their functional diversity," D. said. Peter Roopnarine, Curator of Geology from the Academy.

Understand This helps us to understand if the system has moved on to favor species with different stress responses.
