EVOLUTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Embryology is the study of developing organisms. Which of the following best describes how embryology relates to evolution?
A
Embryology has proven that organisms of different species do not share developmental similarities
B
All living organisms share the exact same characteristics while developing
C
Embryology allows scientists to compare the anatomical similarities of developing organisms of different species
D
Embryology does not provide evidence for evolution
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Embryology, the study of the development of the anatomy of an organism to its adult form, provides evidence for evolution as embryo formation in widely-divergent groups of organisms tends to be conserved.

Detailed explanation-3: -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-4: -Embryology Evolution Evidence Darwin’s theory of biological evolution noted that all vertebrates have gill slits and tails in early stages of embryo formation, even though these features may be lost or modified in the adult-form phenotype. For instance, human embryos have a tail that becomes the tail bone.
