This isn't a discussion about zoology or hominid evolution, as JayJay is ignorant of the necessary knowledge to participate fully and only wants to peddle his ideology. Because he doesn't understand the difference between a "symbiotic relationship" and "tool use" he calls it a "voodoo doll" because it doesn't fit with his whacky ideology. Same for group size. That alone trumps his argument hands down and therefore it is a "voodoo dool."

Sorry I still have to reply to posts when I have the time. This point has been occupying my mind though.

What you don’t understand is that habitual use of something that isn’t the self-e.g. a weapon in the case of the pompom crab and a stick and stone in the case of Australopithecus – sets up a relationship that over time and through natural selection, is likely to change the body to make that relationship more effective in relations with the environment. If the something-that-isn’t-the-self happens to be another species then the changes are reciprocal and if its also beneficial then the relationship is called symbiosis. So symbiosis results from particular habit. It’s empty to claim that the pompom crab’s habit is “symbiotic” therefore it’s not the same as australopith weapon carrying-and-use. That’s why I said you were shaking the word “symbiosis” in my face like a voodoo doll.

The only thing stopping us from calling the hominin-stone system symbiotic is that the stones didn’t breed differentially. Or did they? Weapons radiated into the broader class of “tools”? Tools co-evolve with Homo? Why am I sitting here with a keyboard and a screen? That issue has been worked over in SF one way or another for many years. But anyway our intense and intimate interest in weapons and in tools and our facility to use hand weapons at speed with precision and decision is inherited from ancestors who faced that necessity if they were to forage on the savanna in the face of skilled sympatric predators and skilled alternative prey.
