Volume becomes important when you talk about the risk of extinction. The result, published in the Proceedings of the National Academy of Sciences, explains that one of the most important extinction risk factors is body strength.
The research team revealed that if the largest and smallest animals in the world, which live on land and water, have a high risk of extinction.
The team studied birds and mammals, and found that species with large body size would normally be extinct. But not only, the researchers found other things quite surprising.
