New hypothesis of language evolution. Language Evolved due to an "animal connection" according to Pat Shipman:
Next, the need to communicate that knowledge about the behavior of prey animals and other predators drove the development of symbols and language around 200,000 years ago, Shipman suggests.
For evidence, Shipman pointed to the early symbolic representations of prehistoric cave paintings and other artwork that often feature animals in a good amount of detail. By contrast, she added that crucial survival information about making fires and shelters or finding edible plants and water sources was lacking.
"All these things that ought to be important daily information are not there or are there in a really cursory, minority role," Shipman noted. "What that conversation is about are animals."
Of course, much evidence is missing, because "words don't fossilize," Shipman said. She added that language may have arisen many times independently and died out before large enough groups of people could keep it alive.
Nothing but wild conjecture as usual but still interesting.
