The human animal - hominid researcher Friedemann Schrenk

Friedemann Schrenk is an international star on the scientific research scene. In 1991 he made a sensational find in Malawi: a 2.5-million-year-old human jawbone.
He examines questions such as what factors contributed to the development of humans. What role did climate change play? And when did we begin to separate ourselves from our closest relatives on the extended family tree? A report by Andreas Neuhaus.
