Question

which of the following provides evidence of evolution from a common ancestor? select all that apply. a. homologous structures b. fossils c. fertility rates d. analogous structures e. biochemical similarities

Explanation:

• A. Homologous structures: Structures with similar anatomy (e.g., human arm, bat wing) indicate a common ancestor as they share a structural origin.
• B. Fossils: Fossil records show transitional forms and species' changes over time, supporting common ancestry.
• C. Fertility rates: Relate to reproduction rates, not evolutionary common ancestry.
• D. Analogous structures: Evolved for similar functions (convergent evolution), not from a common ancestor.
• E. Biochemical similarities: Similar DNA, proteins, etc., across species suggest a shared genetic heritage from a common ancestor.

Answer:

A. Homologous structures, B. Fossils, E. Biochemical similarities
