.The difference between sexes in age predicted based onmethylation is mainly due to differences between sexes of "socially mature" animals (after they gain their social rank). This finding supports the conclusion that:

Likely that social hierarchy is affected also by genetics. Finding DNA methylation levels associated with social hierarchy, is therefore an indication that epigenetics and genetics are not independent of eachother.

This study predicts that where males have to compete over high social rank in order to reproduce, DNA methylation patterns will indicate that investment in reproduction shortens lifespan.

Do you think that the changes in the DNA methylation levels in "clock sites" are causing differences in gene expression levels that accelerate aging?

It was well established that we can follow the patterns of genetic variation (mutations) and use this genetic information to make a molecular clock. Several studies, as this one, demonstrated that we can make a molecular clock also based on epigenetic variation.What do you think could be a difference between these molecular clocks?
