MAYBE NEADERTHALS DID TALK!

Ground-breaking research by an expert from the University of New England shows that our 'misunderstood cousins,' the Neanderthals, may well have spoken in languages not dissimilar to the ones we use today.

Pinpointing the origin and evolution of speech and human language is one of the longest running and most hotly debated topics in the scientific world. It has long been believed that other beings, including the Neanderthals with
whom our ancestors shared Earth for thousands of years, simply lacked the necessary cognitive capacity and vocal hardware for speech.

Associate Professor Stephen Wroe, a zoologist and palaeontologist from UNE, along with an international team of scientists and the use of 3D x-ray imaging technology, made the revolutionary discovery challenging this notion
based on a 60,000 year-old Neanderthal hyoid bone discovered in Israel in 1989. It was virtually indistinguishable from that of our own species. This led to some people arguing that this Neanderthal could speak," A/Professor Wroe said. However advances in 3D imaging and computer modelling allowed A/Professor Wroe's team to revisit the question.

"By analyzing the mechanical behavior of the fossilized bone with micro x-ray imaging, we were able to build models of the hyoid that included the intricate internal structure of the bone. We then compared them to models of modern humans. Our comparisons showed that in terms of mechanical behavior, the Neanderthal hyoid was basically indistinguishable from our own, strongly suggesting that this key part of the vocal tract was used in the same way.

"From this research, we can conclude that it's likely that the origins of speech and language are far, far older than once thought."
