Which of the following is most directly involved in the evolution of these variations in metamorphosis?

A) artificial selection of sexually immature forms of insects.

B) changes in the homeobox genes governing early development.

C) the evolution of meiosis.

D) the origin of a brain.

B. changes in the homeobox genes governing early development.

Explanation:

There are certain groups of genes that participate in the early stages of the development of all animals, these genes are called Homeobox, which determine what will be "anterior", "medium" or "posterior." Some mutations in Hox genes cause one segment to acquire the characteristics of another (homeotic mutations).
