Nonhuman 'Hands' Found in Prehistoric Rock Art

The roughly 8,000-year-old "hands" painted on a rock wall in the Sahara Desert aren't human at all, as researchers originally thought, but are actually stencils of the "hands" or forefeet, of the desert monitor lizard, a new study finds. "It completely changes the way we think about prehistoric people," said lead study researcher Emmanuelle Honoré, a research fellow at the McDonald Institute for Archaeological Research at the University of Cambridge in the United Kingdom.
