``Hobbits'' might have descended from first tiny humans to leave Africa
A new analysis of ``hobbits'', an extinct race of tiny hominids, has suggested that they descended from the first tiny humans to leave Africa, and this might have happened some 2.25 million years ago.
In a new research, genetic evidence is revealing that human populations began to expand in size in Africa during the Late Stone Age approximately 40,000 years ago.
