This conclusion is buttressed by the FOXP2 evidence (all humans share the same derived gene) and by the fact that genetic data point to all modern humans descending from a common ancestor [ 19].
These considerations suggest that the anatomical, neurological and physiological underpinnings of language are shared among all of humanity. If the capacity for language did evolve more than once, all traces of it seem to have been lost. This conclusion is buttressed by the FOXP2 evidence (all humans share the same derived gene) and by the fact that genetic data point to all modern humans descending from a common ancestor [ 19].
