Developmental biology: the study of life cycles of organisms to find common
Molecular biology: the analysis and comparison of DNA to better understand relationships between species
comparative anatomy: the study of the anatomy of an organism to explain evolutionary similarity
Explanation:
Embryology can be described as the branch of biology in which studies about the sex cells, the process of fertilization and the development of the fetus or embryo are made. The similarities between the embryos show evolutionary history among different organisms.
Developmental biology can be described as the branch of biology in which studies are made about the processes of growth and developmental procedures about organisms. Organisms belonging to different groups can also show developmental similarities if they have a common ancestor.
Molecular biology is the branch of biology which is related to the study of life on molecular level. At this level, similarities between the genome of organisms can be checked for evolutionary histories.
Comparative anatomy: It is the branch of biology in which organisms are studies based on the similarities and differences in their structures.
