The branch of biology known as evolutionary-developmental biology is the study of:.
A. the development of multicellularity.
B. how changes in development underpin the evolution of
morphology.
C. cell-cell signaling.
D. cell adhesion molecules

B) how changes in development underpin the evolution of  morphology.

Explanation:

Evolutionary developmental biology is the new field of research in biology which studies the combined relationship of the evolution and the developmental processes.

This interdisciplinary study compares the developmental biology in terms of evolution or in a way that how the developmental biology process evolved in the organism on the basis of studying the phenotypic features of the organisms.

Thus, Option-B is the correct answer.
