Goal
Use the modules and review resources to complete the chart on this handout
Goal
Use the modules and review resources to complete the chart on this handout comparing pelvis and other bipedal features of the chimp, human, Australopithecus afarensis, Homo erectus, and Homo neanderthalensis skeletons. Refer to the module page for images needed for this assignment.
Instructions
Refer to the module page Pelvis Images for the Assignment (Genus Homo) for images and 3-D rotations of the four pelvises you need to describe and compare. You can also look at Comparing and Measuring the Pelvis (Genus Homo)
Open the worksheet An111 Comparing Genus Homo pelvis shape-1.docx Download An111 Comparing Genus Homo pelvis shape-1.docx and fill out the table to compare features across the species. The rows will ask for one of the following types of answers.
Simple descriptions and comparisons are fine for our purposes, Review:
Present or absent: When a feature is either there or not, you can use a + for present and – for absent.
For example, “presence of sagittal crest” can be answered + or –.
Describe: When you are asked to describe a feature, do so with a few words or short phrase.
For example, “shape of dental arcade” can be answered “U-shaped.”
Compare: When you are asked to compare, you need to ask “compare to what?”
For Example: If there are three skulls being compared, you might say X and Y are smaller than Z. Or X is smaller than Y and Y is larger than Z.
Measure: Use the measurements you collected
Measurements gathered from teaching materials at LAVC. All measurements are in millimeters
