Las causas de la migración del humano a América fueron las glaciaciones y el nomadismo. Las consecuencias de esta migración fue la formación de comunidades y civilizaciones humanas en América.
El humano desde sus inicios como especie tuvo la idea de migrar o trasladarse de un lugar a otro en busca de recursos para sobrevivir. Esto hizo que luego de su surgimiento en África migrara en diferentes direcciones poblando todo el continente hasta llegar a los demás continentes cercanos (Europa y Asia).
Durante glaciación de Würm en la parte norte de Siberia se congeló el océano formando un puente que unió a Asia con América. Este fue el lugar que permitió la migración humana al continente americano.
Años más tarde, estas comunidades nómadas descubrieron la agricultura y se establecieron en distintos lugares formando grandes civilizaciones como:

- Los Aztecas
- Los Incas
- Los Olmecas
