(WA-LC) Well, if there are no more questions I would like to continue our discussion of human evolution by looking at Homo erectus, the earliest of our ancestors who stood upright. Homo erectus lived about one and a half million years ago and was given that name because, at the time the first fossil was discovered, it represented the first primate1 to stand upright.

There is evidence now that Homo erectus had sharper mental skills than their predecessors2. They constructed the first standardized3 tool for hunting and butchering. They created an extraordinary stone implement4, a large teardrop-shaped hand ax whose design and symmetry reveal a keen sense of aesthetics5. This detailing, along with the ax's utilitarian6 value, strongly suggest that Homo erectus had the ability to conceive of and execute a design to specification7.

In addition, Homo erectus was the first hominid [HAH muh nid] to use fire. This discovery enticed8 them to cook meat, which they could flavor and keep from spilling by flame, and which paleontologists now believe may have given them a new disease. Some fossil bones of Homo erectus are grossly deformed9, and paleontologists have noted10 that this condition is similar to that found in people today who have been exposed to chronic11 overdoses of vitamin A. Apparently12 Homo erectus first got this disease by eating large amounts of animal liver.
