Timelines

Human migrations to and within the land now referred to as the Americas began long before European colonization. Within the continents, many tribes practiced seasonal migration, moving for more abundant food and climate conditions. One widely held theory about the peopling of the Americas is that humans migrated from Siberia by way of the Bering Land Bridge roughly 20,000-30,000 years ago. However, this and competing theories are speculative, due to discontinuities in evidence, and  conflicts with the creation beliefs of many indigenous tribes. Numerous other pre-Columbian migrations are speculated to have originated in Polynesia, Africa, Asia, and the Middle East. Maryammmm
