Module 5.1: Introduction to Skeletal System:
In this introduction we will examine some of the unique features of the human skeletal system, specifically evolutionary oddities such as bipedalism.
Module 5.1 Warm-Up : Skeletal Anatomy
- Directions: Use the notes from watching "Human Origins - Bones" to complete the 5.1 warm-up.
-Pick one of the many features in the human skeletal anatomy as presented throughout the video. (Please collaborate with your groups so that each member researches a different feature)
1) Begin by describing why this feature is unique to humans. In your explanation, please include the evolutionary process and reasons why this feature is unique.
2) Next, look into some detail BEYOND the information presented in the video. You have a lot of freedom here but some ideas/options for research are: what is this feature like in other mammals or primates? what are some other skeletal adaptations similar to this outside the mammalian world? What other body systems, organs, structures, behaviors or features also evolved alongside this feature? Any other additional information would be great!
Essential Vocab:
