One Pair, One Year: How Quickly Could Rabbits Multiply?
Researchers revisited Fibonacci’s rabbit-growth puzzle with a model assuming five kits per litter, maturity at three months, monthly litters, alternating litter sexes, and zero deaths. Under these conditions, a single pair would reach 1,182 rabbits by New Year’s Eve and about 345,000 by the end of the second year, though real-world constraints like disease, predators, and food limits would keep populations in check.
