Several species of caribbean anoline lizards have evolved from a single ancestral species. the species occupies a wide variety of ecological niches, such as tree trunks and the ground, or tree trunks only, or tree trunks and the crown of trees, etc. this type of allopatric speciation is called.

The options needed to complete the question are

A. adaptive radiation.

B. alloploidy.

C. autoploidy.

D. hybridization.

The RIGHT ANSWER IS A.

A. adaptive radiation.

Explanation:

Adaptive radiation

It's a form of evolutionary biology. In Adaptive radiation there is a relatively fast evolution of many species from a single common ancestor I.e a specie changes rapidly from an ancestral species into a different or groups of new forms.

It mostly occurs when an organism lives a new area and different traits affect its survival. E.g development of mammals after the extinction of dinosaurs.

the sun's light combined with the visible wavelenghts form what is called ultraviolet radiation, which are the long waves at the end of a visible light sprectrum.

all these collisions do one thing, and that thing is explained in the last option. when dusst, rocks and ice collide, they harden and form giant layers of rocks or hard ice.

d)   to harden materials to form different parts of earth’s layers
