I always thought naked mole rats live long because they are eusocial
Well subterranean mole-rats in general (describing the shape, nothing else is in the same genus as NMRs) also live longer than mice and rats. I do think the eusociality plays a role too!
Another unique-ish thing about naked mole-rats, in addition to their high average lifespan, is that they don’t age (or don’t age much) in the demographic sense (ie their annual probability of dying is close to flat). I don’t think worker ants or bees work the same way though the data on this is scarce.
I am curious: What is the theory?
In addition to eusociality and the subterranean environment (=lower predators from a non-adaptive evolutionary perspective, = lower oxidation from a mechanistic/biological perspective), naked molerats’ rather unique form of queen selection may mean that living longer confers reproductive advantage, similar to lobsters.
So there’s an evolutionary incentive to live longer/having later-in-life deleterious mutations are costlier.
Since the NMR extrinsic mortality rate is low, the reproductive advantage conveyed from being slightly older doesn’t have to be as high as for other animals, in the standard nonadaptive framework.
Can elaborate more if needed.
Agreed narrowly, though like Haiku said this is a highly unreasonable hypothetical and it’s not at all clear to me that model answers on questions like this say much about their performance in real-world ethical dilemmas (or in general).
