As per the research conducted by scientists and published in a paper in researching about the Royal Society B, “The mollusks species which are not in existence reported to have higher metabolic rates in comparison to the species exist in modern times.”
Metabolic rates are the energy that a living being requires to carry out all their activities of routine life. A researcher and a paleontologist, Luke Strotz, University of Kansas, author of the paper, stated a high BMR (basal metabolic rate) has already shown some more chances of death at an individual level.
He told NPR, “But it increases the level of species are most prominently the big discoveries of the research.” It means that the things happen at individuals’ level, and when we scale it up to the level of species and observe that the species with higher metabolic rates are actually more prone to be at the verge of extinction.
Scientists considered 299 species of mollusks and their metabolic rates those were in existence during the mid-Pliocene era, duration of approximately 5M years. Researchers specifically monitored a bivalve which includes mussels and clams and gastropods like slugs and snails.
Strotz says, “Mollusks are among the species with longer fossil records,” that help the researchers to find out their metabolic rate even after their extinction, and all these is not limited to this; the scientist can trail back to the starting of the animal life with the remaining.”
He further states that earlier studies have shown that the extinction of the species is linked to the things such as the size of the areas a species needs, the population of the species, and the connection in between the species present during the same timeframe.
He states that we are hoping to increase the team size to conduct the study further with vertebrates, until then, we cannot conclude anything.
