Epigenetic marks are constantly added to and removed from CpG sites on the genome, controlling gene expression and thus cell behavior. The pattern of epigenetic marks in any given cell shifts in response to environment and circumstances, and some of those changes are characteristic of the presence of the underlying molecular damage of aging. Epigenetic clocks can thus be constructed from weighted combinations of epigenetic mark status at various CpG sites in order to measure biological age. Existing epigenetic clocks are specific to a given species, but here researchers process an enormous amount of data from many species to produce epigenetic c…
