Which of the following explain why divergence and fixation of traits can occur more rapidly on islands compared to other geographical locations? Please select all that apply.

Question

Quizplus · Accepted Answer

When species are isolated, as on an island, limited interbreeding with individuals from other locations occurs, meaning that the different populations develop differently over evolutionary time. If the original population of a species that arrived at an island was small, then this can also lead to accelerated divergence, due to the differences in the original genetic diversity of the founder populations in different locations. This can also apply to other types of location, not just islands, if reproduction between individuals from different regions is limited. Islands do not have high rates of species exchange because they are isolated, and land-based species do not usually travel easily between islands. There is no suggestion that reproductive rate is generally higher on islands.
