Problem: Utilizing an anthropological perspective, answer the following questions:
Given what we have learned so far about natural selection, taxonomy, genetics, and macroevolution, what does the scientific evidence tell us about a common ancestor for all living things on Earth? What specific evidence (physical, molecular, or behavioral) supports this hypothesis? Describe the key homologies (characteristics) that connect humans and other non-human primates with other animals in our taxonomic grouping (hint: use the taxonomy).
Provide references, please.
