BBC E-mail: Colourful ancient art 'is alive'

I love petroglyphs. They are one of my favorite arforms. I saw this story on the BBC News website and wanted to share..
Colourful ancient art is alive;
A particular type of ancient rock art in Western Australia maintains its vivid colours because it is alive, researchers find.
