This question already has an answer here:


Do Koi have a lifespan of hundreds of years? Do humans have a lifespan of decades? Do dogs have such a short lifespan?

Within these questions I pose further questions. How does size relate to lifespan. Elephants?

If dogs were to evolve independent of humans (at this point) would they rule the world?

  • $\begingroup$ An interesting question and @Wesley has answered it quite nicely. Apart from this, I would like to direct you to a neat article published by Yaneer Bar-Yam in PRL last year on when does natural selection favour limited lifespans. A detailed explanation was given in Gizmodo website last year. $\endgroup$ – Shab86 Dec 16 '16 at 18:52
