A new family portrait
Five skulls that date back 1.8 million years from Dmanisi, Georgia, are raising new debate about the classification of some early human ancestors. A new study suggests that Homo habilis, Homo rudolfensis and Homo erectus were all the same species. In recent decades, a widely accepted view, depicted here, has held that H. habilis and H. rudolfensis were distinct species from H. erectus, a predecessor of H. sapiens, or modern humans.
