Final answer:
Anthropology is the study of humanity across time and space, examining the cultural, social, and biological aspects of humanity including both ancient and contemporary societies.
Step-by-step explanation:
According to Danilyn Rutherford's essay, anthropology is the study of humanity across time and space. It examines the cultural, social, and biological aspects of humanity, which means that it focuses on more than just ancient civilizations and human biology. Anthropology also encompasses the study of contemporary societies and how different cultures fit together. Therefore, both statements 'c. Anthropology examines the cultural, social, and biological aspects of humanity.' and 'd. Anthropology only deals with contemporary societies.' are true.
