How music has evolved or changed throughout the ages isn't as simple as "it began with instrumental and evolved into vocal".

• It's really hard to tell if the history of music started with humans using their voices or using basic instruments. As far as I know no evidence exists that proves that one predates the other. If you're going to use your theory that instrumental music evolved into vocal music you'll have to provide proof to ack it up. Also, there's the possibility that some groups of people started with instruments while others used their voices first, making the whole argument rather pointless.

While this isn't evidence, this sort of illustrates my point that it makes more sense that vocals came first.
