Laney Lab Exercise: Comparative Anatomy April 13
Comparative Anatomy Exercise:
After viewing “Prehistoric Autopsy: Lucy” (see link to video in “Announcement” on Canvas for this week) please complete the following lab
Steps to Complete This:
- Go to eskeletons.org – this will be the source of your virtual skeletal material. Explore the site, get to know how to get to bone material, and how to get to text material
- Using the bone imagery there, and in your textbook, please answer the following questions:
- Compare the shape of the femur of a chimpanzee, a modern human, and Australopithecus afarensis.
- Are the condyles of the distal femur more similar between Australopithecus afarensis and a chimp, or a modern human (Homo sapiens)? Describe them, and support your conclusion
- Are the head and neck of the proximal femur more similar between Australopithecus afarensis and a chimp, or a modern human? Describe them, and support your conclusion
- Compare the shape of the femur of a chimpanzee, a modern human, and Australopithecus afarensis.
- Note that the chimpanzee femur is very straight, while the A. afarensis and H. sapiens femurs are shaped differently. Why is that?
- Using your own anatomy, stand up. Lock your knees. Take a few steps. Answer these questions:
- When standing, why is it important that you can lock your knees?
- When walking, why is it important that your hallux (big toe) is parallel to the other toes?
- Your tibia are vertical (at a 90 degree angle) to the ground when you stand upright. How about your femur? Is it in line with your tibia, or does it angle out?
- Using the internet, look up video of a chimpanzee walking bipedally. Are you a better biped than that chimp? Using your anatomy, explain why:
