Music has always been considered the Universal language. Even animals produce music. As a matter of fact some of the greatest works of music were written imitating animal or bird sounds. So, for one, just in case I have some Neanderthal DNA, do not wish to look down upon them. They were probably more intelligent than you think.
I possess some ancient flutes created by PreColumbian Native Americans that are downright amazing and priceless.
I know your statement is well intended, but we should not take our predecessors lightly.
