Use the two images below to identify the species of the individuals. HINT: you have cranial slides in your lecture notes that cover the differences. A) Homo sapiens, B) Homo heidlebergensis A) Homo erectus, B) Homo sapiens A) Homo sapiens, B) Homo neanderthal A) Homo neanderthal, B) Homo heidlebergensis Correct answer: A) Homo sapiens, B) Homo neanderthal Below is a diagram of two types of molars. Using your notes and textbook, identify

which tooth type belongs to which group. Booth tooth types belong to Neanderthal A) Nontaurodont teeth belong to Homo sapiens, B) Taurodont teeth belong to Neanderthal. Both tooth types are associated with Homo sapiens Correct answer: A) Nontaurodont teeth belong to Homo sapiens, B) Taurodont teeth belong to Neanderthal. What does this gene tree of mtDNA from 277 humans from around the world say about our origins? What does it say about genetic diversity in the Americas in comparison to Africa? Explain your answers. It shows that our origins are mostly from Africa because it shows the beginning of the tree with African data. The beginning of the tree shows us the beginning origins of humans/homo sapiens. It shows lower genetic diversity in the Americas and higher in Africa. What potential impact did the higher population density and longer lifespan of Homo sapiens have on their ability to out-compete Neanderthal?

They were able to develop better and stronger qualities to out-compete Neanderthals. They developed advantages like hand-eye coordination and other skills like it. With these skills they were able to evolve and develop hunting skills. With skills like these, Homo sapiens could survive longer and out-compete Neanderthals. What tool types can you identify from the diagram? Acheulean hand axes Magadelian flakes Correct answer: Needles, Awls for drilling, scrappers, and blades
