How can analogous structures be distinguished from homologous structures?

How can analogous structures be distinguished from homologous structures?
  1. By comparing the structures and determining whether they are anatomically similar
  2. By comparing the structures and determining whether they perform similar functions
  3. By comparing the structures and determining whether they share a common ancestor
  4. By comparing the structures and determining whether they have evolved due to adaptation

Solution

Analogous structures can be distinguished from homologous structures by comparing the structures and determining whether they perform similar functions, even though they may not be anatomically similar. Analogous structures are a result of convergent evolution, while homologous structures indicate common ancestry.
