Really? How does it relate to finding food?

Even without aging, organisms would have a finite lifetime, since predation, accidents, and infectious disease are factors. I’ve seen an estimate that even if aging were abolished, the average human lidespan would be ~600 years because of accidents, homicide, etc. Aging greatly increases the odds of getting caught by a predator and of not finding a mate, as I noted in the article. Without aging, fitness doesn’t decrease over time.

A single golf clap? Or a long standing ovation?

By clapping more or less, you can signal to us which stories really stand out.
