Looks like a load.

In a statement, lead author Ceri Shipton, an archaeologist at ANU, notes that the primitive peoples "really don't seem to have been pushing themselves." He adds, "I don't get the sense they were explorers looking over the horizon. They didn't have that same sense of wonder that we have." ...Comparatively, Neanderthals and early Homo sapiens expended much energy on resource collection.

This sounds more like lazy thinking by Ceri Shipton. I wonder how often Dr. Shipton has tried to survive in the wild by making his own stone tools and whether he would be able to keep up hunting wild gazelles and antelopes with the "lazy" Homo Erectus.

How in the world do scientists come up with this stuff? Maybe Homo Erectus was just plain stupid.
