Explanation:
Detailed explanation-1: -These likenesses in structure, called homologies, are the result of descent from a common ancestor. In related species, the same anatomical features evolved into distinct forms as they were used in different environments or for different functions.
Detailed explanation-2: -Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor.
