What is an example of homologous structures?
Understand the Problem
The question is asking for an example of homologous structures, which are anatomical features in different species that have a similar origin but may serve different functions. This relates to comparative anatomy and evolutionary biology.
Answer
The limbs of humans, cats, whales, and bats.
The limbs of humans, cats, whales, and bats are examples of homologous structures.
Answer for screen readers
The limbs of humans, cats, whales, and bats are examples of homologous structures.
More Information
Homologous structures are anatomical features that are similar in different species because they inherited the feature from a common ancestor. Over time, these structures may evolve different functions, as in the case of the arm of a human and the wing of a bat.
Tips
A common mistake is confusing homologous structures with analogous structures, which serve similar functions but do not originate from a common ancestor.
