At the end of the ice age, (9,500-14,800 years ago), people in what is now Michigan used hand-thrown spears with stone tips to kill animals as large as mastodons. As time passed and the climate warmed, they developed atlatls that let them throw spears farther and with greater force.
Some 1,000-1,500 years ago, they began using bows and arrows, which allowed them to shoot further and with more accuracy. No matter what tool they used, they had to be expert stalkers and know the habits of their prey.
