Structures found in different species that are believed to have a common evolutionary origin are called:
- A
Homologous
- B
Analogous
- C
Vestigial
- D
Fossilized
Homologous organs can be defined as the organs of different animals that are similar in structure but perform different functions. Homologous organisms share a common ancestry. Hence, the correct option is A.
Homologous organs can be defined as the organs of different animals that are similar in structure but perform different functions. Homologous organisms share a common ancestry. Hence, the correct option is A.
Analogous structures are similar structures present in unrelated organisms. Structures are similar because they are made to do the same job, not because they evolved from the same ancestors. This option is incorrect.
Vestigial structures are structures that have lost their use over time. Vestigial structures may be inherited by related lineages, but it isn’t necessary.
Fossilized structures aren’t believed to have a common evolutionary origin. Structures with common evolutionary origins are called homologous structures.
