Final answer:
Paleo-Indians lived in small groups called bands and traded women to ensure genetic diversity.
Step-by-step explanation:

In terms of finding a mate, regional Paleo-Indian groups would come together yearly in the summer months. This gathering allowed them to celebrate religious rituals, exchange news, and trade women to ensure genetic diversity amongst their groups.
