Homo Erectus Research Paper

The Homo erectus was believed to have lived about 1.89 million years ago in North, South, and East Africa; western and east Asia. They possessed a human like body with the ability to stand upright with its elongated legs, shorter arms compared to the torso and a slightly larger braincase relative to the size of the face. With these discoveries in the fossilized anatomy it seems that these features are adaptations for a life lived on the ground. They had the ability to walk and possibly run long distances compared to other earlier fossil humans, there is fossil evidence that this species cared for weak and older individuals. Homo ergaster is sometimes categorized as a subspecies of Homo erectus. Homo ergaster can be distinguished by its thinner skull bones, smaller, orthognathic face and dental arcade, and larger cranial capacity. Homo ergaster was estimated to be able to stand at about 6ft tall and have a reduced sexual dimorphism compared to earlier hominins. In features the ergaster have a tall slender body, flatter face, projecting nose and an expanded brain case. Fairly similar features as Homo erectus including the ability to stand upright and jaw structure. …show more content…
Both seemed to use tools, technology and culture to gather and hunt for enough food to sustain nutrients for their larger brains. Ergaster in greek means the “workman” a rightful name after the discovery of left behind various tools such as cleavers and handaxes that were discovered closely to the Homo ergasters bony remains. Both seemed to have the ability to make a fire and cook their food. The Ergaster have left behind traces of charred bones from their old campsites. These simple tools are considered unique to its species at the
