Question

Organisms with homologous structures likely

• A. share a common environment
• B. share common ancestry
• C. share common behavior patterns
• D. have increased genetic diversity
• E. have decreased genetic diversity

Answer 1

The correct option is B share common ancestry

Homologous organs are the organs that have the same basic structure but perform different functions. When the same basic organ becomes adapted by specialisation to different functions, evolution occurs and homologous organs are formed. Thus, homologous organs share a common ancestry.

So, the correct answer is 'share common ancestry'.
