Title. Why do our bodies stop growing at one point and begin to decline in function? If the purpose of life is to live and reproduce, wouldn’t it make more sense to continually evolve and live forever? Also don’t our cells constantly regenerate? So if they do then why do they start to die out?
In: Biology
Iirc, there are a lot of reasons. But one od the onez I find interesting are telomeres. This are proteins that are at the end of strands of DNA. As cells divide, the telomeres will start to shorten until the cells are no longer able to divide which causes aging.
Some of this aging will cause organs to stop functioning as efficiently, and adding in minor little mutations that can occur over time such as diseases and cancer, you get death via natural processes.
