What im asking is would a mayfly experience time the same way a human would in his/her lifetime? if the mayfly lives for only a day, a perceived lifetime almost?My question is, the timescale of living things, we have the Mayfly — The Shortest LifespanMayflies live about a year. It's just that they don't last too long after puberty, not even retaining the means to eat.
As for long-lived things, every amoeba is arguably tens of millions of years old. They're not born, so its hard to define when they 'started'. Just saying, not everything goes through the steps of birth, growth, repro, and death.
Many creatures have aging and death built into their genetic makeup, including us. It was an evolutionary adaptation that made the species more fit.QuoteOr is life just based in human time life spans?Don't know what you mean by this. Is it measured in terms of human life spans? No, it's usually measured (by us) in hours, day, years, or more standard (to us) units of time like that. I don't think you're asking that, but I cannot figure out what you actually are asking.
