You should know What are the triggers for glaciations. What are the triggers for Major Cold Periods (Ice ages). Which hominid first had the ability to make fire. How

many years ago? Was there time overlaps in bipedal hominids? What is the difference between science and technology? What skills is the US deficient in, according to Glenn

Seaborg, to maintain its leadership in science and technology?

What you should know
