I wonder if the "upper brain" segment, so pronounced in mammals could be associated with the "meme machine" of Susan Blackmore, et al. In other words, I wonder if whereas genetic evolutionary pressures were responsible for the lower and mid sections of the brain, it would be interesting to explore if "memetic" evolutionary pressures were largely involved in the development of the upper brain. A related point I find interesting is inherited hard-wired behavior. I read somewhere that infants might have a 'facial recognition template' that enables them to recognize the female humanoid face, e.g. the mother, and this template is 'pre-progammed' into their brain, without having to be learned. If so, this would represent I think an example of a meme. The female humanoid face could be a meme in some sense, which is hard-wired into the "upper brain" segment of the infant. Just as the mid and lower sections of the brain are focused on the promulgation of the "Selfish gene", perhaps the sole purpose for the existence of the upper brain is the promulgation of the "selfish meme", i.e. the upper brain is the "meme machine", and consciousness (and ourselves in the sense of 'self' for that matter) is sort of an accidental by-product of the meme machine - it is better for the meme for there to be 'itentionality' about its replication, 'intentionality' is found in consciousness, ergo, we have consciousness. Anyway cool article, and I like the intro video explaining embryonic brain development in the humanoid.
