The startling discovery was made in 2007 by an international team, including the palaeoanthropologist Curtis Marean from the "Institute of Human Origins" of the Arizona State University and three graduate students of the "School of Human Evolution and Social Change". They came to the conclusion that humans living in the cave started to eat new foods. They added shellfish and other marine resources to their diet. The cause for this evolution was the climate change. It is the first evidence that mankind was able to this. The report in the magazine Nature also reports that the evidence for using coloured pigments was also found. This is much earlier than the earliest known usage which had been from 70,000 years ago.
