Solution

The correct answer is "evolved from the same ancestor".

Homologous structures are parts of different species that are similar because they evolved from a common ancestor. These structures may look different and perform different functions, but their underlying structure and development are the same. This suggests that these species share a common ancestor.

For example, the human arm, the wing of a bird, and the flipper of a dolphin all have similar bone structures, suggesting that they evolved from a common ancestor.
