The development of stone tools and other weapons for use in hunting. Use of fire Increased use of built structures? 7 Homo erectus the big game hunter? Emphasis on hunting increased. There is disagreement about the significance of big game animals in the Homo erectus diet. Big game hunting would required cooperation of groups of people during hunts and the development of stone tools and other weapons for use in hunting. 8 How skillful were Homo erectus hunters? Although H. erectus was clearly able to capture small game, opinion is divided over the extent that they systematically hunted larger animals. The remains of elephants, horses, and deer in sites with Acheulean tools are sometimes cited as evidence for cooperative hunting of big- game animals by H. erectus. Other researchers doubt this and suggest H. erectus obtained the remains of these large animals through scavenging carcasses left by nonhuman predators 9 Acheulean tools associated with large mammals

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
