Do not worry if you raise a lethargic child, especially if your child is a mollusk.

A study by the University of Kansas has attracted international attention, suggesting that laziness could be a fruitful survival strategy. But the lead author of the study, Luke Strotz, a postdoctoral fellow at the KU Institute for Biodiversity and Natural History, says the study is not necessarily true for individual humans.

The research is based on mollusc fossils, "but, I would like to believe that the results are a real phenomenon," said Strotz. "I'm talking about species concepts and how a whole species reacts physiologically."

Molluscs are invertebrates such as snails, snails, clams and octopuses. They have a soft body ̵

1; most of them have outer shells – and live in aquatic or humid environments.

The study "Metabolic rates, climate and macroevolution, a case study with neogenic mollusks" was published in the Proceedings of the Royal Society B.

The question was: Could you estimate the likelihood of extinction of a species based on the energy intake of a Consider organism?

It was about finding a kind of representative metabolism for this whole species and then looking at how much energy they absorb and how much energy they consume.

"The species that do more of it absorb more and are more likely to die out than the species that do less, and that's essentially the story," Strotz said.

The research is not & # 39; I say that all extinction is based on it.

"It's not all and extinction, that's not the case," Strotz said. "But what this study is doing for the first time is to show that metabolism and physiology are a component of extinction and no one has done that before – no one has shown that before."

Strotz did not expect the results he found. He thought he would discover the opposite.

"Just because we see something at the lower level of the individual does not mean that it goes up to the species level, and biology is quite complex as we evolve from individuals to populations, to species, to entire species communities We do not expect phenomena that apply at lower levels to necessarily apply at higher levels. "But it did.

About a year ago, Strotz began thinking about the idea of ​​considering the likelihood of extinction of a species based on the energy intake of an organism. He co-authored work with KUs Julien Kimmig, collection manager at the Biodiversity Institute, and Bruce Lieberman, KU Professor of Ecology and Evolutionary Biology, and Erin Saupe at Oxford University.

It took a good year of studying the fossils. He says the human point of view was played in the British media. It does not bother him because it draws people to work.

"I think the most interesting side here is anything that potentially predicts the likelihood of extinction or contributes to our understanding of why the species that exist today are here and why these organisms are here, because it matters

Strotz hopes people will realize that extinction is complex, but researchers are finding out what causes and causes extinction over time.

"We are undergoing major changes with climate change and temperature is a driver of metabolism," he said.

"And how will that affect biodiversity on the planet? It's a very complex story, but that helps us build that story," Strotz said.
