- One of the main characteristics that defines the hominin tribe are their bipedal tendencies. However, as you have noted in reading for this week's assignments, not all hominins had the same bipedal capabilities. Early hominins can be defined as being at various stages of transitioning into bipedalism while later forms are obligate bipeds. At the same time there are many other things that we can explore that relate to hominins. Often times there are new discoveries that are made and those discoveries make the news.I would like you to share a news article that specifically deals with hominins. The news article can be up to 10 years old. Make sure you do the following for points. Note: Make sure that the news that you read only deals with one of the following genera - Sahelanthropus, Ardipithecus, Australopithecus. Give a brief summary of what you read. In one short paragraph tell the class what the news was about. Include the following points. Name the species in question.
