The main way individuals are added to the population (with animals) is the birth of new offspring.
New individuals are mainly added to a population through reproduction, either sexually or asexually. This process involves the combination of genetic material from two parents to produce offspring with a unique genetic makeup.

Migration of individuals into or out of a population provides a source of genetic variation. This movement introduces new genes into the gene pool, increasing diversity within the population.
This is known as founder effect, a phenomenon where a small group of individuals migrates or is isolated from a larger population, establishing a new population with genetic differences from the original population due to the limited genetic diversity of the founding members.
Australia has a population of 23.2 million people and New Zealand has a population of 4.51 million. The two populations, when added together, equal 27,710,000.
