Question Description

I'm working on a anthropology discussion question and need a sample draft to help me study.

3.6 Hominins: From walking on two legs to running on two legs (Graded Assignment)

  • Due Jan 24 by 11:59pm
  • Points 10
  • Submitting a text entry box or a file upload
  • Available until Jan 29 at 11:59pm

Beginning in the late Miocene and into the early Pliocene, upright walking tendencies began to develop among the hominin tribe. Upright walking tendencies slowly transformed into obligate bipedalism during the pliocene within the hominin lineage. This shift in locomotor strategy is notably marked by the gradual change in arm to leg ratio that we see when comparing early and later hominins. Early hominins have short legs and very long arms while later hominins have longer legs and short arms.

What you are doing.

Your task for this activity will be to compare and contrast the locomotor strategies of the following three hominin species: Ardipithecus ramidus, Australopithecus afarensis and Homo erectus. You will accomplish this by answering the questions below

Use the following resource for Ardipithecus (Links to an external site.) (Click)

Use the following resource for Australopithecus (Links to an external site.) (Click)

Use the following resource for Homo erectus (Links to an external site.) (Click)

Before you begin make sure to view all unit material so that you can give me informed opinions.

What you are doing for points.

  1. Before you begin make sure view all relevant reading material so that you can give me informed opinions.1. Which hominin had the best arboreal capabilities? Make sure you explain your answer by talking about only one feature that backs up your claim. Choose only one feature from the lower extremities (Legs and feet).2. Which hominin was the first to have feet that are effective for habitual bipedalism? Briefly explain what makes their feet more effective for bipedalism when compared to previous hominins.3. Which hominin had the best anatomy for running on two legs? Briefly explain how you would know and tell me about two specific skeletal features that suggest that your chosen species was running on two legs.4. Lastly, I would like you to give a short summary of the notable evolutionary changes in locomotor strategy (the way that you move around) that you notice occur over time as seen from the perspective of Ardipithecus ramidus, Australopithecus afarensis and Homo erectus.

Tips for success

  • Please keep your answer to only what is asked in the assignment.
  • I recommend composing your content offline in a text editor and then copy and paste the text into your reply post. If something happens you will have an offline copy of all of your hard work!
  • I highly recommend using Google Docs (Drive) to compose offline, as Google plays well with web-based forums. If you are using Microsoft Word to compose offline, you may need to do some editing to the format when you paste it into the reply.
