Paragraph 1: Archaeologists believe that humans first arrived in North America at least 16,000 years ago and that by 11,000 years ago, these migratory hunter-gatherers (people that hunt for and collect food in the wild) had spread throughout North and South America. For some time, archaeologists believed that the region of Amazonia (the Amazon rainforest in South America) was not occupied until much later. However, it has since been proven that hunter-gatherers first entered Amazonia at least 11,200 years ago.
