Look Who's Talking!

A study by Fox et al published in the journal Current Biology explained how Neanderthals may have had advanced languages like modern humans today, and not the stereotypical Neanderthal gruffs and grunts. 

They extracted the DNA sequence for the FoxP2 gene from Neanderthals. This gene is significant because modern humans have several changes in this gene that is absent in chimpanzees, our closest living relatives. This suggests that the FoxP2 gene plays an important role in the evolution of modern human language. Speech is one of the key characteristics that separates us from the chimpanzees. It was discovered that Neanderthals also shared the same mutations in FoxP2, suggesting that they were capable of language and speech. 

It makes me think, if modern humans and Neanderthals once shared this planet, could it be possible that we communicated with one another before they went extinct?
