Solution
The correct answer is: the similarities between them reflect common ancestry.
Homologous structures are those that have a similar structure and are found in different species, indicating a common ancestry. These structures may not necessarily perform the same function. For example, the human arm and the wing of a bird are homologous structures. They have different functions but share a common structural theme that points to descent from a common ancestor.
Similar Questions
Homologous structures are anatomical features that are similar in different species because they were inherited from a common ancestor. For example, the forelimbs of humans, whales, and bats.
