Well detailed.

1. Patterns of natural and sexual selection have created some interesting features to evolve in primates, as they seem to cue for genetic quality, fertility, or strength. Write and explain about 2 examples of traits in specific primates that demonstrate the result of this selection.

2. Even though there are so many primates, we know that some nonhuman primates are more closely related to eachother than to others. (A) How do primatologists/biologists determine the taxonomic relationships between primates (Hint: think about structural features like those we have discussed and genetics that reveal these relationships)? (B) Which group is most related to humans and how do we know?
