It takes 465 years to reach 1billion population from start

[sigma boii]

Given:

• Initial population = 2

• Breeding pair = 2 animals

• Reproduction rate = Each pair breeds every 5 years, producing 1 offspring.

• Lifespan = 100 years

• Breeding starts = Age 20

• Breeding ends = Age 40

• Goal = Reach 1 billion (10⁹) animals.

It will take approximately 465 years for the population to reach 1 billion under these conditions.
