Richard Engel journeys to Tanzania for 'Hidden Planet' series

Rock Center

In the second installment of Rock Center's Hidden Planet series, NBC News Chief Foreign Correspondent Richard Engel travels to Tanzania, a land where mankind is believed to have begun.

Engel journeys through the land's volcanoes and valleys, visiting the Maasai and Hadza tribes.  The Maasai tribe lives at the base of Mt. Kilimanjaro.  They live off the land and are one of a 120 tribes in the region. 

The Hadza tribe lives just 25 miles from where man's first footsteps were discovered.  Researchers believe the Hadza have lived in the region for 15,000 years, maintaining a hunter gatherer existence.

In an unexpected departure from his usual beat of war-torn territories and areas of conflict, each month Engel’s Hidden Planet will set off on journeys of discovery to find the most awe-inspiring, rarely seen locations around the globe. From the Lost City of Timbuktu to the tunnels beneath the Giza Pyramids, and everywhere in-between, this is a side of Engel - and the world - that viewers have never seen before.

The Hidden Planet series debuted earlier this month on the iPad app for Rock Center with Brian Williams.
