Dunbar's number

Thanks for making the real point of my post for me in your comment! I have been fascinated for some time now by how it is more likely that human language is based on forming and preserving and extending social relationships than from a desire to share information as such. Dunbar's number by itself is little more than a random factoid until it is put into this larger narrative of the social evolution of language. So again, thanks for getting this post properly contextualized. And happy grooming!
