(CNN)If you think burning calories is the best strategy to preserve you from extinction, well, we may have bad news.
Using more energy on a daily basis increases the chances of a species becoming extinct, with those that are more sluggish and use less energy being more likely to survive, a new study suggests.
Researchers looked at 300 million species of mollusc that lived in the Atlantic Ocean over a period spanning roughly five million years and found that those with a high metabolism were more likely to follow the fate of the dinosaurs and disappear from the planet.
Conversely, those with lower energy maintenance requirements -- who use less energy -- were more likely to still be around today.
The reason why gastropods (such as sea snails and sea slugs) and bivalves (such as mussels and scallops) were considered for the study is the sheer magnitude of data sets available, the authors said.
Does this mean Darwin's "survival of the fittest" evolutionary theory should turn into a "survival of the laziest"? The authors of the study think so.
"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," Kansas University's Bruce Lieberman, co-author of the study, said in a statement, adding that maybe a better metaphor for the history of life is "survival of the sluggish."
