Survival Of The Laziest

Now, I’m no mollusk but I do know that as I’ve aged I’ve slowed down . . . along with my metabolism.  Turns out this is GOOD news:

Less Active Species May Live Longer

“This is what a group of researchers from the University of Kansas found after taking a close look at some extinct as well as living species . . . analyzing the physiology and evolution of as many as 299 species of aquatic mollusks — including present-day snails and slugs — over last five million years.”

“They delved into the occurrences and extinction of different species over the said period as well as their respective metabolic rates or the amount of energy each of the creature in question needed for survival.”

“Much to everyone’s surprise, the findings of the work revealed that metabolic rates make a reliable factor for predicting the likelihood of extinction of a certain animal species or community of species.”

“We found a difference for mollusk species that have gone extinct over the past 5 million years and ones that are still around today.  Those that have gone extinct tend to have higher metabolic rates than those that are still living . . . those that have lower energy maintenance requirements seem more likely to survive than those organisms with higher metabolic rates.”*

“Maybe in the long-term the best evolutionary strategy for animals is to be lassitudinous and sluggish — the lower the metabolic rate, the more likely the species you belong to will survive . . . Instead of ‘survival of the fittest,’ maybe a better metaphor for the history of life is ‘survival of the laziest’ or at least ‘survival of the sluggish.'”**

I was going to go for a brisk walk but I’ll take a nap instead and . . .

live to walk another day.

Oh my goodness! Here’s synchronicity in real-time.
