Neanderthals probably froze to death in the last ice age because rapid climate change caught them by surprise without the tools needed to make warm clothes, says an Australian researcher.
Ian Gilligan, a postgraduate researcher from the Australian National University argues his case in the current issue of the journal World Archaeology.
By the time some Neanderthals developed sewing tools it was too little too late, says Gilligan.
Well, you can't reap what you don't sew!
