What is the most likely reason that horses and mountain goats have hooves? they have homologous structures because they have a common ancestor. they have analogous structures because they have a common ancestor. these are vestigial structures in both animals because they are not used. these are similar structures due genetic mutations.

They have homologous structures because they have a common ancestor.

Explanation:

The correct answer is the first statement.

Explanation:

Homologous organs are those organs that are similar in skeletal level or in origin but show dissimilarity in functions which suggests that they have diverged from the common ancestor.

Horses and mountain goats have hooves that they have a similar structure but show dissimilarity in functions as they have different habitats.

Thus, the correct answer would be the first statement.
