Goal
Use the modules and review resources to complete the chart on this handout comparing skull features of the chimp, human, Australopithecus africanus, Homo habilis, Homo erectus, Homo neanderthalensis, and Homo sapiens. Refer to the module pages for images of skulls of the species.
Instructions
Refer to the module page Skull Images for the Assignments (Genus Homo) for images and 3-D rotations of the skulls you need to describe and compare. You will also find Comparing and Measuring the Skull (Genus Homo) useful.
Open the worksheet An111 Comparing Genus Homo Skulls.docx Download An111 Comparing Genus Homo Skulls.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
Use these measurements gathered from teaching materials at LAVC to calculate the condylar index and the facial index. All measurements are in millimeters

Grading
Learning and growth take practice and reflection and I am here to support your efforts. All assignments will receive an initial grade based on the provided rubric. If you aren’t happy with the points you receive or need to improve your submission, everyone will have the option to review my feedback, revise your work, and resubmit your assignment by the “available until” date 1 week after the original due date. If you have questions about how to improve a submission or about my feedback, please ask me.
Week 13 – Skull Images for the Assignments (Genus Homo)
Skull Images and 3-D Rotations to compare Skulls
In the Genus Homo Skull Measuring Assignment and the Comparing genus Homo Skulls Assignment this week, you will want to look at the species from a variety of viewpoints. Please use the following tools to make your descriptive comparisons. Anything that needs to be measured will be a static picture with a yellow ruler in the assignment, or I will tell you the actual measurements for you to calculate indexes and compare across species.

Also, have a look at this Homo sapiens fossil from Ethiopia, dated about 150 kya. It is a very early example of our own species. The skull is called “Idaltu” and sometimes Homo sapiens idaltu.

This is an example of a more recent Homo sapiens fossil. So even within our own species, there have been changes over time. This specimen is referred to as Skhul V. You can read more about early examples of Homo sapiens on eFossilsLinks to an external site..

Australopithecus africanus (a similar but slightly more recent species than Australopithecus afarensis who we used last week)
You can review the features seen in A. africanus from Week 6 – Meet the Ancestors (Ardipithecus and the Australopithecines))
