Something confused me, "More than ten generations of frogs have passed since the accident and a classic, although very fast, process of natural selection may explain why these dark frogs are now the dominant type for the species within the Chernobyl Exclusion Zone."

What does this mean since the accident was in 1986 and frogs breed annually. How long is a frog generations?

From the scientific article:

>Females start to breed at 2–3 years of age (Özdemir et al., 2012), which means that 10–15 generations have passed since the Chornobyl accident.

2022-1986=36 years

Divide by 2.5, which is the approximate number of years it takes for a newborn female to reach maturity = about 15 generations of new reproductive females.

Thank you! That is surprising, I didn't realize how long lived and slow breeders they are.
