Humans and a subterranean rodent have contrasting biological rhythms.

Abstract

Here we show that naked mole rats (NMRs) have an extraordinary survival advantage. We base this statement on a spectral analysis of the time series of measured intervals in teeth of 3 species (NMRs, Killer Whale, and Modern Humans). We used Fourier decomposition to analyze the variability of these intervals. We find these animals go through their long life without any of the age-associated diseases seen in humans such as osteoporosis or cancer and they show no signs of muscle atrophy or slowing of mobility. Global warming will delay its effects on these animals whereas for humans it is a clear and present danger.
