What is a primary evolutionary driver for the miniaturization of the Virgin Islands Dwarf Gecko?

Answer

Intense selective pressure to require fewer resources

The evolution towards extreme miniaturization in island species is often a response to intense selective pressures. Smaller individuals require fewer resources to survive, and their diminutive stature allows them to utilize scant microhabitats, such as the thin layers of leaf litter, which provides a significant advantage in resource-limited island environments.
