Q Goal and Purpose • To explore the various theories on the origins of bipedal locomotion in human ancestors over the last six million years of human evolution. • To evaluate which theory you find to be the most likely explanation for the origin of bipedalism in humans (possible theories listed below and discussed in this week's audio/visual lecture in the module). o Savanna Hypothesis - Raymond Dart (1924) o Provisioning Hypothesis - Owen Lovejoy (1981) o Thermoregulation Hypothesis - Peter Wheeler (1991) o Patchy Forest Hypothesis - Rodman and McHenry o Postural Feeding Hypothesis - Kevin Hunt (1994) • View the film clips on bipedalism and early human origins. • The Discovery of ArdiLinks to an external site. • The Discovery of LucyLinks to an external site. • PBS Eons - When We First Walked UprightLinks to an external site. • View The Origin of Us with Dr. Alice Roberts.Links to an external site. Prompts If you are the first person to post in your group, then you should start the discussion using my prompts below: Please re-state the "hook question" from your peer at the beginning of your post and/or the prompt(s) that you are responding to at the beginning of your post. Prompt # 1 Based upon the information provided in this week's module (lecture, reading and film clips) describe at least three of the main theories on the origin of bipedalism in humans. What are the evolutionary advantages and disadvantages to bipedal locomotion? Prompt # 2 Out of the theories that you discussed above, which theory do you find to be the most likely explanation for the evolution of bipedalism in humans and why? Initial Post You will complete this discussion in a "hook format." This means that you only need to post one time and you need to reply to the student who posted before you. Please end your response with a question that the next student can hook on to. Please re-state the "hook question" from your peer at the beginning of your post and/or the prompt(s) that you are responding to at the beginning of your post. You are welcome to take any stance that you would like in this discussion - all you have to do is be able to back up your argument. It's okay if the conversation naturally moves away from the initial discussion. As long as the subject matter remains anthropological, you can take the conversation wherever you would like it to go. Please directly cite lectures, textbook, article and approved film clips (those found in the direction and/or that week's module) in your response in order to support your argument. Remember to think critically! Examine the the evidence presented, consider the speaker, consider the arguments coming from your professor and classmates and, ultimately, decide for yourself! • Please make sure that your responses are organized into complete sentences. I recommend that you devote at least one full paragraph to answering each discussion prompt. • Your final post should be at least 300 words. • You should exercise college-level writing skills with correct spelling, grammar and punctuation. • You should include reference to at least three academic resources throughout your initial post. • I highly recommend that you first type out your response in a Microsoft Word document and run a spell and grammar check prior to submitting your final post.

Resources Academic Sources and Citations: Approved academic sources include: • Chapter 9 (Links to an external site.) from the Explorations textbook. • The Origin of Bipedalism and Early Hominins Audio & Visual lecture. • Academic Journal articles (found in the weekly module or in the library data bases) • Approved films and film clips (found in the weekly modules) Please note that Wikipedia and other internet sources are NOT approved academic sources. You should include properly formatted in text citations whenever referencing a source. The Owl Purdue site is a very useful site when learning to properly cite your sources. Here is the link to the Owl Purdue Website for APA format: (Links to an external site.) Examples of In-Text Citations: To cite a textbook, article or PowerPoint slide, please include the last name of the author or authors followed by the year of publication, for example, it would look something like this (Miller 2018) or (Smith and Taylor 2014). These are just examples. To cite a film or film clip, please include the last name of the director or directors followed by the year of publication. For example, it would look something like this (Stevens 2017) ***Please note, that the author or authors of the Explorations textbook are included at the beginning and end of each chapter.
