we don't know nothing.. the more time it passes the more clear to me that we can't know anything based on "external" science. we can just use the "internal" science (that is , verifying with our experiences anything we want to probe)
eating a summer squash vaporized for 3-5 minutes is not going to kill you, and you even will digest it really quickly. Is that being adapted to cooked?
maybe we are "adapted" (what is to be adapted?) to cooking, but not 100% cooked foods! (again, whats the goal here? to live long, to live healthy, to enjoy the more varieties of flavors, to create new ones?, alltogheter? what is the goal of adaptation? to make us what? to reproduce? to live long lifes? to live healthy? to conquer the universe? )
maybe our body has "evolved" now to be on a 90% raw and 10% cooked (given the times we have had to adapt to cooked, and that our ancestors HAD been eating cooked) maybe definition of "paleo" is something around 80-100% raw and 0-20% cooked (depending on your bloodline)...
personally i think that as soon as the human discovered fire, and how to control and mantain it, he started to experiment as much as he can with it. due to it being a so new thing, adding a totally new dimension to the reallity they were living. allowing them to create new things, and playing new games on the reallity.
science says it is 300.000 years ago or 150.000 or anything. but these are just speculations on some evidence found. what if the evidence from 500.000 years and before is all gone , for reasons we still don't understand/know?
and maybe the human and the fire are 2 things that were always together and come in the same package hehe
i don't know just leting my mind run and say stupid things =)
