Which species has a lifespan range that begins at 2 years?

Explanation:
Lifespan ranges reflect how long each species typically lives in captivity. For rats, the standard reference ranges commonly show a lower bound around two years, so the range begins at about 2 years. Mice usually have shorter minimum longevities, often around one year, so their range doesn’t start at 2. Gerbils and hamsters can have ranges that start at or above 2 years in some sources, but the most consistently cited lower bound at 2 years is associated with rats. Thus, the rat is the best match for a lifespan range beginning at 2 years.
