I am keenly interested in discussing the, "Social Brain Hypothesis," by British zoologist, Robin Dunbar.
It has a passing mention in a book that I am reading. It has to do with the connection between a primate's brain size and it's typical group size.
I am excited by the idea of it being a link to human consciousness.
Who is well informed on this theory and can help me grasp it and it's implications?
I'm curious as to how this relates to the information related by Robert Sapolsky in Behave: The Biology of Humans at Our Best and Worst (https://www.amazon.com/Behave-Biology-Humans-Best-Worst/dp/1594205078). He's studied apes for about 30 years and has a ton of insight into their behavior and ours. He really gets down to the molecular biology aspects of it. But he doesn't really go into theories of consciousness that deeply - only enough to say he thinks free will is bunk (like most folks in neuroscience).
I'd also be curious to know if and how this idea might mesh with Julian Jaynes theories in The Origin of Consciousness in the Breakdown of the Bicameral Mind (https://www.amazon.com/Origin-Consciousness-Breakdown-Bicameral-Mind/dp/0618057072).This is the idea that were all like folks who have schizophrenia in the past, where when one part of our mind is talking to the other, it seemed like it was the voice of gods telling us what to do (of particular interest to those who are interested in the cultural evolution of the religious mind-virus). BTW this theory is currently being illustrated and popularized somewhat by the TV series Westworld. I recommend it for a lark.
Of course, Daniel Dennett suggests consciousness is a kind of generated-on-the-fly user interface that only instantiates according to what's demanded of the organism in the moment in From Bacteria to Bach and Back: The Evolution of Minds (https://www.amazon.com/Bacteria-Bach-Back-Evolution-Minds/dp/0393242072).
What's the book you are currently reading the references Dunbar?
I personally have fondness for the aquatic ape theory as an explanation for the evolution of both the human brain structure and the reasons behind hominid social cohesion.
Though largely dismissed, a few others and I, still find it a satisfying explanation by reason of diet and the ingestion of larger amount of omega 3, for at least for the species diversification between humans and the other great apes, if nothing else.
