Evolution and Aging
Death is viewed as a result of evolutionary processes, with no inherent programming for mortality. Organisms are optimized for reproductive fitness rather than longevity, leading to different life spans across species. For example, smaller animals like mice typically have shorter lives due to higher predation risks, while larger animals benefit from a longer lifespan, enhancing their reproductive opportunities. The relationship between size and longevity illustrates the varying evolutionary pressures that shape different species' lifespans.
