What is the study that focuses on similarities and differences between organisms?

• A. Comparative biology
• B. Comparative anatomy
• C. Comparative genetics
• D. Comparative physiology

Answer: (B)

The study that focuses on the similarities and differences between organisms is comparative biology. This field encompasses various aspects of biology that allow scientists to compare different species, examining how they are alike and how they vary. Comparative biology provides insights into evolutionary relationships, adaptation, and the functioning of organisms within their environments.

While comparative anatomy, comparative genetics, and comparative physiology all examine specific aspects of organisms — such as their physical structures, genetic composition, and biological functions, respectively — they represent subsets of the broader field of comparative biology. Comparative biology integrates these individual disciplines, allowing for a holistic understanding of the diversity and similarities across different life forms.
