Hunter-gatherers offer the closest existing examples of human lifestyles and social organization in the past, offering vital insights into human evolutionary history. There are approximately 1500 Agta hunter-gatherers in Isabela Province (Northern Luzon). The Agta are coastal and terrestrial foragers, the live in small camps (3 to 15 families each), which vary from nomadic to semi-settled. They are egalitarian, practice food sharing and have different degrees of market integration. The Agta are under constant pressure from neighbouring agricultural populations as these populations expand cutting down the forests. However, most Agta camps still maintain their forager lifestyle.
