To Avoid Extinction It’s About ‘Survival Of The Laziest’

A new study claims that being lazy might be a great survival strategy, according to a report by the Daily Mail.

Partially motivated by self-interest-after all, the term survival of the fittest exists for a reason-and partially by the scientific impulse to expand upon the study's findings, one would naturally ask if similar predictions can be made about the human species.

The researchers also considered their findings as another potential predictor of extinction probability.

U.S. ecologist Professor Bruce Lieberman, who co-led the University of Kansas team, said: "Maybe in the long term the best evolutionary strategy for animals is to be lassitudinous and sluggish". But metabolic rate seemed to matter more when a species lived in a smaller habitat, researchers found, and predicted less when a species spread across vast swaths of the ocean. "But these results say that the metabolic rate of an organism is a component of extinction likelihood".

Researchers focused on mollusks due to the ample data available on such species, both living and extinct, from the Atlantic Ocean.

The species Anadara aequalitas was part of a KU study suggesting higher metabolic rates were a reliable predictor of extinction likelihood. "This will increase our understanding of the mechanisms that drive extinction and help us to better determine the likelihood of a species going extinct".

While there are a lot of factors and variants at play when it comes to extinction, the link between metabolic rates and survival of a species is particularly important if we consider the staggering challenges that climate change poses in the near future, said Luke Strotz, postdoctoral researcher at Kansas University's Biodiversity Institute and Natural History Museum and lead author of the paper. They analyzed the metabolic rates of 299 species of mollusks that lived over a period of roughly 5 million years from the mid-Pliocene to the present. So, it's another tool in the toolbox. You no longer need to make excuses and worry about those who complain about your lifestyle.

The interview Wednesday night marked the first time a juror has publicly identified themselves after the trial. Trump added, "If I ever got impeached, I think the market would crash, I think everybody would be very poor".

That means if your species as a whole is already inclined toward using less energy, then you are more likely to survive.

Scientists of the University of Kansas found that laziness can be a successful strategy for the survival of individuals, species and communities of organisms.

A recent study found people who scored high on a scale for how much they daydream were brighter - and less physically active.

A study of marine creatures over the last five million years found those that were the liveliest were more likely to go extinct.

"We find the broadly distributed species don't show the same relationship between extinction and metabolic rate as species with a narrow distribution", Strotz said.

The team tested the motivating factors behind the survival of species by looking at the evolution of basal metabolic rates (BMR) over time in fossils and now surviving species of gastropods and bivalves collected from the from the Atlantic Ocean. "Can it apply on land?"
