“Humane Hominid” writes at the Discerning Brute:

Energetics and the evolution of human brain size,” published in the November 2011 edition of Nature, tests and refutes the expensive tissue hypothesis. It’s impressive work, and pretty devastating to the hypothesis that has provided a rhetorical foundation to the paleo diet mythology for over a decade now.

Navarrete’s, et. al.’s, main findings (further details below) are:

  • There is no negative correlation between brain size and gut size in any mammalian taxa, refuting the ETH’s prediction to the contrary.
  • There is, however, a strong negative correlation between brain size and adipose tissue deposits; that is, fatter animals have smaller brains than lean ones; and,
  • Humans are seeming exceptions to this rule because our fat deposits don’t interfere adversely with our means of locomotion, thus freeing up energy for encephalization that other primates have to use for carrying around all that fat.

“And the system that brought us here and made us sick is not going to fix us.”

Manning is the author of Against the Grain: How Agriculture Hijacked Civilization, which argued that major world shaping forces, such as trade, imperialism and disease, were conditioned and driven by agriculture, both for good and ill. But, mostly ill.

Manning has now returned for another tilt at civilization with Go Wild: Free Your Body and Mind from the Afflictions of Civilization, co-authored with John Ratey, associate clinical professor of psychiatry at Harvard Medical School and author of such titles as A User’s Guide to the Brain.… Read the rest

You Have Dormant Primal Powers. This Guy Can Unleash Them.

Via- Midwest Real

“You can blend respectfully and mindfully with your environment as you move. This is a high level of mindfulness requested here. In my opinion, this is a physical manifestation and experience of my spirit… I would even say it’s a spiritual experience of my body.”

Do me a favor- stand up. No problem, right? Now walk around. That’s pretty easy, huh? Next, smash the nearest wad of food into your mouth hole. Isn’t this fun? Ok, sit down, look at the screen, and you’re done! Sound familiar? I know to me it does. I practice that sequence of movements with devoutly religious regularity. I’m going to make a tremendously presumptuous leap and assume that you do the same. Isn’t it sad that the mediocrity of our physical habits is that god damn obvious? Yet, if you’re lucky enough to be a normal-ish, healthy-ish human being you’ve got some serious untapped potential.… Read the rest
