[quote] A new analysis of bird bones at Neanderthal sites suggests our extinct human cousins adorned themselves with dark feathers plucked from vultures, jackdaws, eagles and other species.

The study is the latest to challenge the notion that symbolic behavior, like creating art and body decorations, was exclusive to modern humans.

Use of ornaments suggests complex thinking, and the authors of the paper write that their findings assign "unprecedented cognitive abilities to these hominins."[quote]

Then scroll on down the page and see what your cave parents might have looked like. I don't think I see mine. LOL
