The most lazy survive, a research with molluscs



According to recent research, it is the species that saves the most energy, those with a greater chance of survival than those who need more energy.

Traditional evolution theory says that species with a greater chance of survival are "more suitable". Usually that word is understood as an evolutionary advantage, such as being fast, climbing and jumping between trees, or swimming long distances. Moreover, a few thumbs is considered the evolutionary advantage par excellence.

There is, however, an advantage that, according to evolutionary biologists at the University of Kansas, is not taken into account and that it may be the key to deciphering. who are more likely to survive: laziness. In other words, the ability to perform basic survival processes with the least amount of energy that is possible.

The researchers studied 299 species of molluscs that have lived and died in the Atlantic in the past five million years. When they calculated the available data about these animals, they realized that a high metabolic expense was the characteristic that it predicted which species would be the next to die out.

The study, published in Proceedings of the Royal Society B, calculated the resting metabolic cups of each of the species of sea snails, sea snails, mussels and scallops. This number indicates the amount of energy that each of them needs to stay alive.

"We have wondered, is it possible to calculate the probability of extinction of a species based on the amount of energy needed for their organisms?", Responded in the portal Tech Times Luke Strotz, the lead author.

"We found a real difference between the species that are already extinct and those that survive," he said. And it is that, after passing on the data of the resting metabolism with the chance of extinction, they realized that the energy consumption of the 179 extinct species was significantly higher for those who still exist on the planet.

But why can this be? According to the researchers, the fact that a species is more lazy & # 39; is that its organisms need less energy and food to survive. So, They are most suitable in times of scarcity.

However, this phenomenon is not necessarily true for all species. In fact, scientists in their document indicate that this type of analysis works for species that are in small spaces. The impact of metabolic rates varies when they are species in a larger area.

Bruce Lieberman, who also co-directed the study, told The Guardian that "this result does not necessarily indicate that lazy people are the most suitable because in our species it is often those people who use the most resources".

"The laziness of humanity is in fact perhaps our biggest obstacle when it comes to implementing the changes needed to ensure our own survival on this planet," he added.
