well I'm nailing my flag to whenever man settle down and became a herder rather than purely a hunter.
Once you think about it - it just makes sense.
Quote:Copying someone else's idea is easy, thinking for yourself is really hard so I have a hard time believing in multiple origins.
Well the evidence is pretty strong that people doing the same job in different places will often come up with the same ways of doing things.
And all shepherds need a cheap and reliable way of both herding their animals and fending off predators. They also all would have time on their hands that would have been - at least partly occupied in making cordage and dealing with leather and wool and other materials from the animals.
Sling making is incredibly simple - it has to be I can do it
So slings developing at multiple points is perfectly logical.
What sets the sling apart from a spear or bow is the length of time it takes for a sling to be of any use to the slinger. And that's where shepherds again come into their own and why it makes sense to rule hunters out.
Need is the main catalyst for innovation. Hunters already had effective easy ways to produce and use weapons.
But once you have a man who's job is to look after animals rather than hunt them. Spears are of little use. You can't direct a herd at distance with a bow and arrow. So at that point in human history a new weapon was required. Cordage and stones were readily available and shepherds would have naturally been using thrown stones anyway.
Shepherds had the time, materials and need for sling usage.
Nobody else had all three.
All shepherds shared the same needs and skill sets and access to materials.
So multiple points of sling origin make perfect sense. Plus slings were used in cultures on different continents - every one except australia, where herding never took hold.
You can also make almost the same case for arable farming.
Farmers would need an effective way to protect crops, scare birds away, deter larger animals etc.
Slings fit the bill a lot better than bows and spears.
So what's the oldest evidence of animal shepherding and farming ?
I'd think older than 15,000 years.
I suspect if you find the really early herding cultures, you'll also find the early evidence of sling usage.
Once they can produce their own meat, more static societies develop and people start making pots and decorating things for the longer term and that's where I reckon, you're likely to have the earliest images of slingers.
