Over time these hominids began to grow larger than Australopithecus.   They were heavier.  Their jaws were wider with smaller teeth.  Their brains began to develop and grew in size to about 850 cubic centimeters.  This helped H. erectus to be a more successful hunter, to avoid danger, and to communicate.

These people traveled from place to place.  They moved with their food supply.   They ate plants, meat, and maybe insects.  Their meat may have been the prey of other animals or they may have captured it by chasing it into a swamp.
