What best defines homologous structures?

• Structures in different species that are similar in function but not in origin or anatomical structure

• Structures in different species that have a common ancestor and are similar in anatomical structure

• Structures that are a result of convergent evolution

• Structures that are present in only one species and have no relevance to other species

How can one distinguish between homologous and analogous structures?

• By examining the complexity of the structures

• By comparing their functions

• By analyzing their evolutionary history

• By the location of the structures in the body
