Why are some areas more endemic than others?

Because endemic species are only found within one region, areas that have more endemic species tend to be in more remote or isolated regions. Islands, peninsulas, or extreme habitats are more likely to have endemic species living there as the animals have had less (or perhaps no) opportunity to travel outside of their original habitats.
