Human impact increases instances of which random events?

Question

Quizplus · Accepted Answer

Both the bottleneck effect and the founder effect can be increased by human impact, as the reduction of genetic diversity caused by these events can be accelerated by habitat destruction, fragmentation, and isolation. However, human activities usually affect the bottleneck effect more directly, by reducing the size of a population due to habitat loss, exploitation, or disease outbreaks, for example. On the other hand, the founder effect can be enhanced by human-mediated dispersal of organisms to new environments where only a subset of the original genetic pool is present. Genetic drift is a non-random evolutionary force that can also be affected by human activities, but it is not mentioned in any other option.
