WebSecond, somatic evolution has several unique features that complicate application of insights gained from studies of evolution in natural populations. These unique features need to be considered and incorporated into a larger conceptual framework of somatic evolution to fully unlock explanatory and predicted power of Darwinian framework. A somatic mutation is a change in the DNA sequence of a somatic cell of a multicellular organism with dedicated reproductive cells; that is, any mutation that occurs in a cell other than a gamete, germ cell, or gametocyte. Unlike germline mutations, which can be passed on to the descendants of an organism, somatic mutations are not usually transmitted to descendants. This distinction is blurred in plants, which lack a dedicated germline, and in those animals that can reproduce asexu…
