The society of these first ancestors was one of pack animals bound together for mutual benefit and protection under the leadership of an alpha male.They were territorial, yet nomadic as territories became depleted. Most importantly, in the wolf, we can see a fairly unique trait they share among the species capable of vocalization that remain non-lingual they sang.Once that innovation occurred, use for signaling not just prey, but alarm and victory would surely have followed.
It requires not just a condition, but a purpose intended to be addressed by the actions of others.
After the hunt, some scholars, looking to present-day simians, believe that triumphant vocalization was utilized to celebrate success.
Also, trumpets were only used as signaling devices, not instruments generally in the earliest civilizations.
(Rams horn Shofar from Microsoft Clip Art Library) When the population and technology of early Egypt reached the point of permanent settlements and non-agrarian occupations, the stage was set for the first imperialism.
What sounds like howling for no reason to us, was the very first music and came well in advance of spoken language or even homo-sapiens.
Evidence has been found at ancient pre-human sites suggesting that our ancestors music did not stop with vocalization.
The oldest known recognizable instrument is a Cro-Magnon bone flute from 44-40,000 BC.
However, ancient horn trumpets cannot be distinguished from other Pleistocene and Neolithic uses of animal horns.
By the peak of the last ice age 22,000 years ago the other proto-humans that survived the Sumatran super-volcano in 70,000 BC (which reduced the homo-sapiens to perhaps hundreds, and one mitochondrial study indicated as few as 12 couples of child-bearing age) had dis-appeared.
When the glaciers had receded and human civilization began to emerge 9,000 years ago, the Neolithic Revolution had transitioned hunter-gatherers to farmers. Pipes, bells, flutes, harps, drums and string instruments were seen from Africa to the North-East Asian coastline.
They were hunter-gatherers, though unlike wolves, their lack of natural weaponry was offset by their increased brain function and rare status as not only tool users, but the first complex tool makers. For the proto-humans, the voice was a critical tool just as it is for the wolf.
