The discovery of the 1.8 Ma Georgian Dmanisi skulls in the early 2000s, which exhibit several similarities with early Homo, has led to suggestions that all contemporary groups of early Homo in Africa, including H. habilis and H. rudolfensis, are the same species and should be assigned to H. erectus.
OH 7 (Olduvai Hominid № 7), also nicknamed "Johnny's Child", [1] is the type specimen of Homo habilis. The fossils were discovered on November 4, 1960 in Olduvai Gorge, Tanzania, by Jonathan and Mary Leakey. The remains are dated to approximately 1.75 million years, and consist of fragmented parts of a lower mandible (which still holds ...
Furthermore, H. habilis was long thought to be the ancestor of the more gracile Homo ergaster (Homo erectus). In 2007, it was discovered that H. habilis and H. erectus coexisted for a considerable time, suggesting that H. erectus is not immediately derived from H. habilis but instead from a common ancestor.

The researchers found that the Dmanisi hominins "cannot unequivocally be referred either to H. habilis or to H. erectus" and that there, in regards to early Homo, was a "continuum of forms"; Skull 5 appears to share many primitive features with H. habilis whereas Skull 1, with the largest brain, is more similar to African H. ergaster/H. erectus ...

SK 847 is the abbreviated designation for the fossilized fragments of a Homo habilis cranium, discovered in South Africa, which was dated to an age between 1.8 and 1.5 million years. This fossil shares morphological traits with the early African Homo erectus, sometimes known as Homo ergaster. [1]
The extinct species Homo floresiensis has long puzzled experts. A new analysis offers clues to the mystery of this tiny oddball’s place on the human family tree.
