What does metamorphosis refer to?

Metamorphosis refers specifically to a significant change that occurs in form or structure, often in relation to the life cycle of organisms such as insects. While "change" is a broad term encompassing any alteration, in the context of metamorphosis, it is most accurately understood as a transformation that involves a complete and often dramatic change in appearance and function. This term is commonly associated with biological processes where an organism transitions from one state to another, such as a caterpillar transforming into a butterfly.

The other options, while related to the concept of change, do not capture the full scope of metamorphosis. "Evolution" typically refers to the gradual development of species over time rather than an individual transformation. "Transformation" is closely related but may not fully encompass the cyclical and specific nature of metamorphosis. "Transition" suggests a shift from one state to another, but does not specifically indicate the intense and complete change usually described by metamorphosis. Thus, "change" serves as a fitting and encompassing term for metamorphosis in this context.
