Does the Ukanuq mentality and maturity show a growth at the same rate as their physiological age? For example, a Ukanuq of 13 years of age has the same mental and physiological maturity that a human of the same equivalent age would have? 13 years of age is around a quarter of the life spectancy of Ukanuq (50 years), so would that make a Ukanuq of said age be as mature as a human of 21 (which is a quarter of the life expectancy of a human at 85)?

Yep, you go it right!
