At what age do beaver kits typically reach sexual maturity?

1. One year

2. Two years

3. Three years

4. Four years

The correct answer is: Two years

Beaver kits typically reach sexual maturity at around two years of age. This timing is significant in the life cycle of beavers, as it allows for the sustainable continuation of the population. By maturing at this age, they can find mates and contribute to breeding before reaching the average lifespan of beavers in the wild, which can be around 10 to 15 years. In addition to reproduction, attaining sexual maturity at two years also aligns with the beaver’s social structure and family dynamics, often involving young beavers remaining with their parents to assist in raising subsequent litters and maintaining the family lodge for up to two years before dispersing. This behavior plays an important role in the survival of the species, ensuring they have the knowledge and skills to thrive in their environment when they eventually establish their own territory.
