One important factor that brought changes to the hunter-gatherer way of life was large prey animals were becoming extinct.
<h3>What led to a change in the hunter-gatherer lifestyle?</h3>
Hunter-gathering was the main way that humans survived before the Neolithic Age brought about agricultural innovations.

The arrival of Europeans of the Old World to the New World brought forth a transatlantic trade referred to as the Columbian Exchange. This was a wide transfer of foods, livestock, disease, and culture in the 15th and 16th centuries that truly changed the course of human history. To the Old World came goods such as tomatoes, maize (corn), and turkey, while to the New World, cows, horses, and sugarcane were introduced (these are only some of the many exchanged goods of the Columbian Exchange).

Epidemics wiped out entire civilizations and resulted in the genocides of an estimated 40-50 million.
On another note, Spanish conquistadors took over the pre-Columbian world. Hernán Cortés conquered the Aztecs while Francisco Pizarro subdued the Incas. Both were aided with advanced with guns and steel weapons, but mainly with disease. A third of the Aztecs died due to smallpox, and the Incans saw a 93% declination in their population
