Researchers in South Africa have unveiled what they call "by far the most complete skeleton of a human ancestor older than 1.5 million years ever found." The skeleton dates back 3.6 million years. Its discovery is expected to help researchers better understand the human ancestor's appearance and movement. The researchers say it has taken 20 years to excavate, clean, reconstruct and analyze the fragile skeleton. Professor Ron Clarke and his assistants found the fossils and spent years to excavate, clean, analyze and reconstruct the skeleton.
