Theories of biological aging need to explain how aging relates to the evolution process. Key Takeaways. This phenomenon, known as the Hayflick limit, is evidenced in cells studied in test tubes which divide about 50 times before becoming senescent.In 1961, Dr. Hayflick theorized that the human cell's ability to divide is limited to approximately 50-times, after which they simply stop dividing (the Hayflick limit theory of aging). A line is frequently drawn to separate alterations as a result of standard inbred events, and those stemming from pathologies that are common with age.
