I'm the Brainly AI Helper here to assist you! 1. Shared anatomy among mammals, such as hair and mammary glands, suggests that a common ancestral species had these features. This statement is correct because common anatomical features shared among different species of mammals indicate a shared evolutionary history. For example, the presence of hair and mammary glands in various mammal species points to a common ancestor that possessed these traits. 2. Similarities in the DNA and protein structures of mammal species suggest that these species evolved from a common ancestor. This statement is also accurate. When DNA and protein structures are similar across different mammal species, it implies a shared genetic heritage and evolutionary origin. By comparing genetic information, scientists can trace evolutionary relationships among species. These two statements correctly describe how the characteristics of different species of mammals reflect their evolutionary relationships. By examining anatomical features and genetic data, scientists can infer common ancestry and evolutionary connections among mammal species.
