Question

Analogous structures are a result of:

• A. Divergent evolution
• B. Convergent evolution
• C. Genetic drift
• D. Point mutations

Answer 1

The Correct Option is B

Analogous structures arise from convergent evolution, where unrelated species develop similar traits due to adapting to similar environments. For example, the wings of birds and insects are analogous; they serve the same function but have different evolutionary origins.

Answer 2

Analogous structures are those that serve similar functions but have different evolutionary origins. These structures arise due to convergent evolution, where unrelated species develop similar traits due to similar environmental pressures or ecological niches, rather than common ancestry.

• Divergent evolution leads to homologous structures, where related species evolve different traits.
• Genetic drift refers to random changes in gene frequencies in a population, not the evolution of structures.
• Point mutations are specific genetic changes at the DNA level and are not responsible for the formation of analogous structures.
