10000 Years Old Tribe
The Hadza people are testimony to some of the oldest living tribal hunting gathering ways, living around the Lake Eyasi in Central Tanzania. It's a tribe that didn't change their hunter-gatherer existence for more than 10000 years. Observing the hunter gatherer tribes of Africa one could mark the Hadza as the last of active hunting gathering tribes. By the observing their DNA, one could not relate the Hadza with any generally known pool or tribe other than the Pygmies. Their language is mostly composed of clicks, and this shows a complete isolation of the Hadza language, both traditionally and technically.
