Genetically, Hadzabe people are not closely related to any other tribes. They are hunter-gatherers and survive by hunting their food with hand-made bows and arrows and foraging for wild honey and edible plants such as tubers, berries and baobab fruits. Up to this day, Hadzabe people remain an important study focus for anthropologists because they represent a modern link to ways of human existence and survival that were abandoned by humanity. 

The Maasai are a pastoralist nomadic people who arrived in Tanzania from South Sudan and now inhabit the African Great Lakes region.

They are one of the very few tribes that have retained most of their lifestyle and traditions.

The Datoga is a relatively unknown tribe for most of those who visit Tanzania. They live in the vicinity of Lake Eyasi in the Rift Valley.
