homo erectus

Homo erectus Michael F. Chapman Jr. Homo erectus was a well-adapted species capable of much more complicated day-to-day tasks. Much of this ability was due to their morphological changes. These changes occurred in the skeletal system and the soft tissues and were tied to environmental factors, tool use, increased meat consumption as well as the more nomadic lifestyle. Changes in the skeletal system included a more robust size with a marked increase in size as …

…of Homo erectus has led to a number of hypotheses seeking to explain the increase. There is general agreement that the larger brain increased our capacity for the development of more complex behavior and more elaborate tool use. Dean Falk has suggested that the increase in the size of the brain was made possible by a change in the drainage of venous blood from the brain that resulted in more efficient cooling of that organ .
