1. used natural resources in every aspect of their lives. They used animal skins (deerskin) as clothing. Shelter was made from the material around them (saplings, leaves, small branches, animal fur). Native peoples of the past farmed, hunted, and fished.
2. American Indians did not always have the bow and arrow. It was not until about A.D. 500 that the bow and arrow was adopted in Iowa some 11,500 years after the first people came to the region. Primary benefits of the bow and arrow over the spear are more rapid missile velocity, higher degree of accuracy, and greater mobility. Arrowheads also required substantially less raw materials than spear heads. A flint k napper could produce a large number of small projectile points from a single piece of chert. Even with the gun's many advantages in the historic era, bows and arrows are much quieter than guns, allowing the hunter more chances to strike at the prey.
