ANTH 131 Grossmont Biology Explanation for Natural Selection Lab Questions
This week in class we will watch the part of the video BBC Origins of Us – Brains that is about Neandertals
In this YouTube video link it is from about 33 minutes to the end:
BBC Origins of Us – Brains (Links to an external site.)
This alternative Neanderthal video is longer, but it quite good and covers a lot of information about this species that is interesting if you have the time:
LAB QUESTIONS
Lab Manual
(L16 p.476-7) Exercise # 4 (parts 1 & 2 – two traits each)
skulls: using the info L16 p.459 – 461, from the class slides, and skull links below *
– describe ~3 cranial differences between Homo heidelbergensis & Neandertals
(L16 p.481) Critical Thinking Questions Chart: Homo heidelbergensis & neanderthalensis
Video, Slides, & Discussion
1. Use the 9 steps of natural selection to explain how Homo heidelbergensis evolved into Neandertals.
2. How do you think Neandertals & Homo sapiens interacted? What evidence is there of these interactions?
3. What do you think is the best explanation for why Neandertals became extinct?
