It's the hard-edge of reason and logic – and the absolutism of viewing everything as a biological adaptation that, for me, resides less-than-comfy next to what seems to be, for lack of any better or less inflammatory terms, a spirit or soul – i can only speak from my personal sense that there exists in this paleo body and brain, something utterly un-related to the biology. I cannot put it into a suitable or accepted context as i will not accept religious ya-ya or cynical dogmatic reason either. If something of this yet-undefinable un-proven and of course argumentative "spirit" was not a component in our evolution yet not connected to it – then i find it hard to figure why we are, for example, on these computers, chatting through all these "big bunch of tubes" – we didn't need to go there in order to spear the next meal or spawn the next offspring.

mmmm – coffee….(he sips again)

To my mind, "conditions" such as ADHD and depression are ultimately caused by an evolutionary mismatch between our paleo brains and modern civilization (most notably, population and pop. density). In this way, I think it seems very analogous to paleo in terms of (some) modern foods being detrimental. Would you disagree?

On your point about a "spiritual/universal" component: I'm having a hard time reconciling that with an evolved brain in the context you've framed. An evolved brain that could sense such things would either have to be adaptive, or a bizarre accident of genetic drift. Aside from "repent unto the lord or I'll kill you", I'm not aware of any particular adaptive advantage to such beliefs.

hhhmmm, the meat between the ears is, of course, biologically strung-up to the past, but i'm of the mind (no pun) that although the brain cheese is bio, the activities in the brain are not so evolutionarily-bogged down in the past (perhaps as we are all interconnected in the ether? kinda esoteric i know) .

i'm not claiming any "science" for this – i just think that our bodies are clearly in need of paleo attention while our thinking seems to thrive (creative person thinking…) on some pretty non-paleo stimulus. I mean – i don't sit around all day thinking about how cold my feet are (gosh shall i invent shoes?) or were are the bits of meaat left over from lat night. (then again, maybe i do…..) Our mental/thought process evolution can be pretty impressive (not Faux News and such) and moves well beyond the past that our body physiology is clearly shackled to (not the ones living on light 😉 )- ie eating modern foods is detrimental but absorbing progressive modern ideas and thinking is more often a positive–

if we're on the same page with the whole evolution bit, which it sounds like we are, how is the part of our bodies between our ears exempt from hanging in the past?
