phenomenon
life span variation
The diversity in maximum life spans across mammalian species, ranging from months to over 200 years.
measurement
epigenetic clock
Age estimator based on DNA methylation levels that uses penalized regression to relate chronological age to methylation levels of individual cytosines
process
DNA methylation
A small chemical modification that occurs in most cytosines that are followed by a guanine (CpGs) in mammalian genomes, serving as an epigenetic marker.
