Founder Population
A founder population is a population that is established by a few individuals who have been separated from the main population and which then evolve in isolation .
If the random fixation of rare alleles , which is orders of magnitude more likely in small populations (see genetic drift ), this population develops into a new species, this is called the founder effect . If this happens several times in a row, for example on a group of islands or a group of nearby lakes, it can lead to adaptive radiation in which several species develop from the small number of individuals in the respective founder populations, which ultimately adopt in different ways can adapt their respective living space . One speaks of allopatric speciation .
