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
Life doesn’t have a purpose the way you’re describing. Life on earth came about because of random chance. some species thrive, some species go extinct, there’s no plan or guiding hand. I pretty much all living things die because the DNA that forms the basis for living things degrades over time when cells divide. Besides, if everything lived forever, that would be a nightmare. And the planet would over populate in a few generations to the point where all plant life was gone, and then everything that eats meat would start consuming each other with no herbivores to fill that part of the food web. You would cause a mass extinction within decades.
