Rate of DNA methylation change and maximum lifespan in mammals
A modeling study of 348 mammal species reported an inverse relationship between how fast DNA methylation changes and the maximum lifespan of each species.

What the research shows
The study, published in Nature Communications, analyzed 348 mammal species. The researchers modeled how changes in DNA methylation in bivalent regulatory regions relate to maximum lifespan. The reported result was an inverse relationship: the faster the epigenetic change, the shorter the maximum lifespan.
This finding should be read with caution. It is a cross-species modeling analysis, meaning a correlation, which does not prove cause and effect. The authors themselves state that such correlations may arise without a real biological signal, so the pattern needs confirmation from other studies. The work is part of the search for biological markers of aging that allow different species to be compared.
What it means
The finding suggests that the speed at which DNA methylation changes may be linked to maximum lifespan across mammals. It is still unknown whether this relationship reflects a biological mechanism, since the authors warn that correlations of this kind can appear without a real signal.
