I think it hinges a bit on your school's Anthro Dept. Some schools have departments more geared towards Archaeology/Evolution than other schools, where archaeology has been kicked out of the Anthro Depts.
Try talking with a TA in the two departments, and see where they're going, and what they think.
edit-
Archaeology isn't the study of human culture, but the study of the remains of human
material culture. So, you could mix it with evolution, you'd just be doing prehistoric archaeology. Just a nitpick
