Which evolutionary phenomenon describes the adaptation of the Virgin Islands Dwarf Gecko to its small island habitats?
Answer
Insular dwarfism or nanism
Insular dwarfism, also referred to as nanism, is a well-documented biological phenomenon where species evolve smaller body sizes when isolated on islands. For this gecko, the reduction in size offers distinct advantages, such as lower resource requirements, the ability to exploit small hiding places like rock crevices or leaf litter, and faster maturity rates, all of which are beneficial in niche environments with restricted space and food.
