Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.

Does a person know when they are dying?

Why can’t living things live forever?

The first is the accumulation of biological defects. Viruses and disease take a toll even after healing; UV rays slowly but inevitably damage DNA; and proteins, cell structure, and the neurons which hold memories all degrade over time due to thermodynamic molecular disruptions and invasions by other species.

Is any animals immortal?

To date, there’s only one species that has been called ‘biologically immortal’: the jellyfish Turritopsis dohrnii. These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle. … Of course, Turritopsis dohrnii isn’t truly ‘immortal’.
