If all organisms are carbon based and and have almost similar functions(cellular etc.), why does lifetime vary across species, demographics etc.
*Lifetime here is average natural lifetime.

There is something called the rate of living theory. Raymond Pearl based his Age of living theory upon the earlier work of Max Rubner and proposed that the maximum lifespan of an animal was related to its metabolic rate sometimes viewed as the number of heartbeats. However this may only be part of the picture with the role of reactive oxygen species in cell deterioration and eventually cell death also playing a part. – https://youtu.be/ctEIbPI6A4U
