Tanzania , Africa

Tanzania is home to some of the oldest human settlements unearthed by archaeologists, including fossils of early humans found in and around Olduvai Gorge in northern Tanzania, an area often referred to as "The Cradle of Mankind". These fossils include Paranthropus bones thought to be over 2 million years old, and the oldest known footprints of the immediate ancestors of humans, the Laetoli footprints, estimated to be about 3.6 million years old.
