Definitions:

Isolated

Being separated from others, either physically or socially, resulting in a lack of contact or interaction.

Demographic Bottleneck

A sharp reduction in the size of a population due to environmental events or human activities, leading to a decrease in genetic diversity and potential survival challenges for the population.

Genetic Drift

A mechanism of evolution that involves random fluctuations in the frequencies of alleles (variations of a gene) in a population, particularly in small populations.
