In what field of science are homologous structures used as evidence for evolutionary relationships?

• A. Evolutionary Biology
• B. Ecology
• C. Biochemistry
• D. Genetics

Answer: (A)

Verified step by step guidance

1. Understand the concept of homologous structures: These are anatomical features in different species that have a similar structure but may serve different functions. They arise from a common ancestor.
2. Recognize that homologous structures are used to demonstrate evolutionary relationships because they indicate a shared ancestry among different species.
3. Identify the field of science that studies evolutionary relationships: This is Evolutionary Biology, which focuses on the origins and descent of species, as well as their change over time.
4. Differentiate between the fields of science provided: Ecology studies interactions between organisms and their environment, Biochemistry focuses on chemical processes within living organisms, and Genetics deals with heredity and variation in organisms.
5. Conclude that homologous structures are primarily used in Evolutionary Biology to provide evidence of common ancestry and evolutionary relationships among species.
