Question

Which of the following is associated with the theory of evolution based on the study of the genetic makeup of species at the DNA level?

• A. Biogeography
• B. Natural selection
• C. Comparative anatomy
• D. Comparative embryology
• E. Molecular biology

Answer 1

The correct option is E Molecular biology

Describing the process of evolution in terms of past and present geographic distribution of species is termed as biogeography. Evolutionary theories based on comparative study of the structural details of features found in different but related organisms reveals the process of evolution in terms of basic similarities and differences among them. These are termed as comparative anatomy. Comparative embryology defines the process of evolution in terms of basic similarities and differences in embryological development. Natural selection is the evolutionary force that favors the mutation conferring “fitness” to organisms thereby leading to the evolution of fittest species. Evolutionary theories based on similarities and differences in DNA sequences of different but related species defines their evolution in terms of molecular biology. Thus, the correct answer is option E.
