title: Why do we need to age?
abstract: Abstract A key question remains: why do multicellular organisms have a limited lifespan? The aging process is considered to be a decline of keeping the molecular, cellular and organ structure and interactions upright. It is hypothesized here that an evolutionary force has actively selected for limited lifespan and prior to that there is the process of aging. Many theories exist, including the endocrine theory of aging and reproduction-based aging. Here, a hypothesis is deduced for the driving force of the evolution of aging and lifespan limitation.
