Biological Anthropology Exam 1 Practice

This item is about how some heritable traits lead to more offspring and thus become more common over generations. The term that describes heritable traits that confer higher reproductive success and increase in the next generation is differential reproduction. It focuses on the differences in how many offspring individuals with different traits produce, which shifts trait frequencies from one generation to the next. Natural selection is the broader process that arises from differential reproduction, while mutation introduces new variation and genetic drift is random change in frequencies.
