Its legs were longer in relation to its trunk length, which suggest, as do other aspects of its anatomy that it was more efficient at walking on two legs. Some arguments can be made as to whether it was early hominids or Homo erectus who first stood. Regardless, this would still be an important feature in human gaining the ability to kill at a distance through weapons such as rifles. This feature would have given these early human ancestor the ability to stand up and see a prey or an enemy from a distance. Along with being able to see ones enemy or prey from a distance, this feature would have also gave the earliest humans the ability to harness the strength in the legs in order to throw farther and more precise. Once early humans gained the anatomical features to throw from a distance, weaponry would evolve vastly from the simply throwing of rocks to killing with more complex and effective
