Describe some of the ways that modern humans' faces, jaws, and teeth changed after the
shift to agriculture and consumption of softer foods.
To test hypotheses regarding modern human origins, it is important to clearly define
what we mean by "modern human." What anatomical features are typically used to
contrast modern humans' physical appearance with that of similar hominids?
What are some of the important scientific discoveries that laid the groundwork for
Darwin's theory of evolution?
Homo erectus and Homo sapiens are two widely recognized hominid species. In
contrast, the hominids that are younger than most Homo erectus fossils but older than
the majority of Homo sapiens fossils have been loosely categorized as "archaic" Homo
sapiens. Why have these fossils not been given a distinct species name, and why do
they remain so difficult to classify formally?
Discuss how physical anthropologists use the scientific method.
Use what you know about meiosis to explain Mendel's law of segregation and law of
independent assortment.
What have scientists learned about the function of primate vocalizations and how they
relate to the evolution of human language?

Linnaeus was not an evolutionist, why is his system still used today by evolutionary
biologists?
Describe the range of primate residence patterns. Relate social grouping to food and
reproduction.
Describe the steps involved in protein synthesis.

regions where Neolithic lifeways appeared independently.
