Repopulation is the phenomenon of increasing the numerical size of human inhabitants or organisms of a particular species after they had almost gone extinct.
An example of an organism that has repopulated after being on the brink of extinction is the Dryococelus australis.[1]
The repopulation of humans after a catastrophic event is a hypothetical concept that sometimes features in fictional as well as traditional literature.[2] In this scenario, only two members of the opposite sex are survivors after some sort of calamity that has happened.[3] This couple, the last two humans on Earth, ends up reproducing and their offspring reproduce with one another, until after a certain amount of time, the planet Earth has a sizeable number of people.[4]
