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

The correct answer is statement a.

Explanation:

The prevalence of shared ancestry between the genes or a pair of structures in different taxa is termed as homology. A common illustration of homologous structures is the forelimbs of vertebrates. A homologous structure refers to a bone or an organ that possess similar underlying anatomical characteristics, which is witnessed in various animals. These compositions hold the notion that distinct animals originated from a common ancestor and serve as the proof of evolution.
