embryology
C

D
fossil record
Explanation: 

Detailed explanation-1: -Embryology is a branch of science that is related to the formation, growth, and development of embryo. It deals with the prenatal stage of development beginning from formation of gametes, fertilization, formation of zygote, development of embryo and fetus to the birth of a new individual.

Detailed explanation-2: -Embryology is the branch of biology that investigates the formation of gametes (sex cells) before fertilization, as well as the fertilization and development of embryos and fetuses, and organisms.

Detailed explanation-3: -The early stages of embryonic development, such as fertilization, cleavage, blastula formation, gastrulation, and neurulation, are crucial for ensuring the fitness of the organism. Fertilization is the process in which gametes (an egg and sperm) fuse to form a zygote.

Detailed explanation-4: -Human Embryology and Developmental Biology is the study of the fascinating process in humans and animals that turns a single fertilised egg into a whole new individual with all the many specialised cell types.

Detailed explanation-5: -Embryology is important to understanding a species’ evolution, since some homologous structures can be seen only in embryo development. For example, all vertebrate embryos, from humans to chickens to fish, have a tail during early development, even if that tail does not appear in the fully developed organism.
