A more widely  accepted hypothesis explains this process as a natural consequence of the trade-off between investment in reproduction  and repair.
Raymond Pearl is considered to be the father of the study of this process, and he developed a theory that explains this  process as a consequence of populations lacking genetic variation to further respond to selection against it. A more widely  accepted hypothesis explains this process as a natural consequence of the trade-off between investment in reproduction  and repair. The antagonistic pleiotropy hypothesis suggests that this process occurs due to a pleiotropic mutation that  confers an (*) early advantage to an organism's fitness. This process, which is the subject of the mutation-accumulation  hypothesis, most likely occurs as cells reach their Hayflick limit due to telomere shortening. For 10 points, name this process in  which an individual's fertility and probability of survival decreases in late life.
