Ancient milky paint

Artists in South Africa who lived almost 50000 years ago, used milk and ochre in their paintings according to a study by researchers at the University of Witwatersrand in Johannesburg and their colleagues at the University of Colorado Boulder, USA. The milk, rather than being from farmed animals, was most likely obtained by killing lactating members of the bovid family such as buffalo, eland, kudu and impala, the researchers say. Either way the discovery by Paola Villa, a curator at the University of Colorado Museum of Natural History and lead study author, and her colleagues pre-dates the known domestication of bovids by humans by many millennia.
