If that's all the data you had it would look like an S curve with an odd starting anomaly at <1 year old.
Example in context:
was applied in three cases: if the animal was (1) transferred to another collection, with the date of
transfer considered as the censorship event; (2) euthanized for research purposes when still healthy,
with the date of sacrifice as the censorship event; or (3) still alive when the process of compiling
records was completed, with the date of completion as the censorship event (see Materials and
I wonder if it would be possible to breed for lifespan by breeding only the 'elders' among them or if it would do about as much good as breeding for resistance to gunshots - outside circumstances not influencible.
Long term project, but in principle.
So this certainly works in principle. For longer lived species I expect it will still work, but it would take hundreds to thousands of years to breed for even a few dozen generations.
You wouldn't want to breed the 'elders' but the offspring of 'elderly' naked mole rats.
I guess we only have had size-able mole rat population for around 30 years.
