Which of the following statements is not true ?
- Sweet potato and potato is an example of analogy
- Homology indicates common ancestry
- Flippers of penguins and dolphins are a pair of homologous organs
- Analogous structures are a result of convergent evolution
Solution
Convergent evolution is the independent evolution of similar features in different and un-related species. Homology is based on divergent evolution whereas analogy/analogous structures are a result of convergent evolution. Analogous organs have different structures, but they evolve for the same function and thus have similarity. For examples, the eye of the octopus and of mammals or the flippers of Penguins and Dolphins.
