WebJan 1, 2024 · Aging and Somatic Evolution. For the last several decades, the link between aging and cancer has generally been recognized as aging representing the time necessary to accumulate oncogenic mutations in cells that drive carcinogenesis ( Armitage, 1985, Armitage and Doll, 1954, Nowell, 1976, Vogelstein et al., 2013 ).
WebSomatic evolution is the accumulation of mutations and epimutations in somatic cells (the cells of a body, as opposed to germ plasm and stem cells) during a lifetime, and the effects of those mutations and epimutations on the fitness of those cells. This evolutionary process has first been shown by the studies of Bert Vogelstein in colon cancer. .
