Answer :
Final answer:
Many mammalian species can differentiate animals by their facial characteristics, despite their genetic similarities. Examples include chimpanzees and humans, as well as domestic dogs. Appearances can be misleading in determining the ability to mate or differentiate animals.
Explanation:
Given the research on facial characteristics, it is likely that many mammalian species can differentiate animals by their facial characteristics. For example, chimpanzees and humans are genetically similar, yet show considerable anatomical differences in their facial features. Similarly, domestic dogs can have phenotypic differences in size, build, and coat, but can still interbreed and produce viable offspring. These examples highlight how appearances can be misleading and do not necessarily determine the ability of animals to differentiate one another.
