This video clip, from the film Bones of Turkana, takes place in the area around ancient Lake Turkana, Kenya. This area is known as a cradle of human life. There is evidence that hominids lived here as far back as 4.2 million years ago.


Dr. Hélène Roche is an archaeologist at the Turkana Basin Institute. She has worked at Lake Turkana for more than two decades, uncovering and piecing back together valuable tools used by ancient hominids. This video gives insight into the beginnings of technology created by hominids and the correlation between brain size and technology.
