______ Structures are Similar in Superficial Form or Function

Question

______ structures are similar in superficial form or function.
A) Analogous
B) Homologous
C) Sympatric
D) Synonymous

Accepted Answer

Analogous structures are structures that have similar functions but differ in their evolutionary origins. They can often arise through convergent evolution, where two unrelated organisms independently evolve similar traits due to their similar selective pressures in the environment. Examples of analogous structures include bird wings and insect wings, which have similar functions in flight but evolved independently from different ancestral structures.
