Nobody wonders if it's good to leave the couch to go for a walk or to run – to accelerate the heart rate, burn up add some calories, maybe even a few years to your life.
But keep in mind: All this exercise can be a selfish act – a short-sighted game of queen in an evolutionary chess game that has been going on for eons. And if you have not left the sofa, you may have taken the first step to saving the species.
Finally, there is a study that, if properly read, can convey the belief in wasting a Sunday (or Monday) or Tuesday) afternoon. Think of it as a not entirely airtight refutation from the American Heart Association, the NFL, to Michelle Obama and the gentle but judgmental reminder of your watch that you've made only nine steps in the last hour.
There is evidence in the form of a scholarly work whose authors are now writing an angry e-mail to the Washington Post. An article in the Journal of Proceedings of the Royal Society B: Biological Sciences found evidence this month that species that consume less energy on average have a better chance of making another rotation around the circle of life.
CrossFit-averse people everywhere can thank Luke Strotz, a postdoctoral fellow at Kansas University's Institute for Biodiversity, who has spent years studying the fossils of mollusks and shells. His most recent study shows that there is a significant correlation between low basal metabolic rate (that is, the amount of energy an organism exerts peacefully) and the evolutionary endurance of a species. The newspaper, he told the Washington Post, gives us more insight into what causes species to die out.
"It is not an all and an end of extinction, that is not the case," Strotz told Lawrence, Kan. Journal-World. "But what this study does for the first time is to show that metabolism and physiology are a component of extinction, and no one has done so before – no one has shown that before."
Its co-author, Bruce Lieberman, a professor of ecology and biology, called it "Survival of the Dreaming."
"Perhaps the long term is the best evolutionary strategy for animals to be lax and sluggish – the lower the metabolism, the more likely it is that the species that is you Lieberman said, "rather than" survival of the fittest, "perhaps a better metaphor for the history of life is the" survival of the laziest, "or at least the" survival of the melancholy. "
The researchers studied the fossils of mussels and gastropods in the Atlantic Ocean. The animals in the study have shells that have a better chance of surviving the passage of time. And they have been extensively studied and cataloged by scientists across North America.
Strotz and his colleagues have compiled a database of approximately 46,000 specimens of nearly 300 species and found that higher basal metabolic rates were a reliable indicator of the likelihood of extinction. "
The reasons remain a mystery: animals may have developed a high metabolic rate because they have a high mortality rate – and they had to grow up fast and reproduce young before they died from predation, he hypothesized Called this the theory, "Live fast, die young." He said more research was needed, even on other species.
But there are benefits to Strotz's study that go beyond the desire to never know What a Burpee is Strotz says his research – and similar studies – can help conservationists understand which animals are most likely to die out due to climate change.
"That could be the canary in the coal mine for us," he said the post office. "We can say that this thing is more prone to extinction. , , We can put our conservation efforts here. "
There are, of course, some caveats that one should know before basing lifelong inertia on a tangentially applicable scientific study: Full transparency: mussels and gastropods are not human, they are invertebrates that live mainly in the ocean, and Netflix has never asked a mollusk: "Are you still watching?"
And there are other variables in the extinction equation that can be affected by pitch (see: giant comets, habitat loss, plague). 19659014] Strotz also said that he talks about the average metabolism of a species, not an individual.
"We're talking about a species level, not an individual level. I had to tell a lot of people that I can not be the champion of the couch potato.
In the last few days he has seen articles about his work around the world, along with images of slippery clichés like Homer Simpson and "The Dude" of "The Big Lebowski." It was not exactly what he was up to as he spent months measuring thousands of mollusks and shells and thinking about extinction.
But despite his studies, that was the first one. When someone googles "rotten mollusk", Strotz says he's happy he has many settled people "Paleontology goes way beyond," here's the newest, biggest dinosaur, "he said," and we're starting to raise big questions about the secrets of life.
to answer. "
