History
I used to be a peen guy. Not the fastest, nor the most skilled or even the bravest—but a connoisseur certainly. I had an appetite for the stuff that eclipsed most others. Whatever was on the menu, I wanted to skip straight to the steepest, chunkiest, rootiest, most bewildering of the lot: the peen. But I am and I was just a mere organism in a system, and systems evolve. One must adapt to survive.
The theory of encephalization holds that around 2-3 million years ago, the brains of early hominids started increasing in size and complexity. The size of the brain is always limited by the pelvis it must pass through. And that in turn is limited by the biomechanics required to keep us upright and bipedal, so there was only so far it could go.
But the simple version of the theory is that in between periods of stasis, the brain underwent three dramatic bursts (encephalizations). Scientists map the stepwise increases in brain size and complexity against punctuated evolutionary change, leading to the modern H. Sapiens and casting off all forbearers.
The point of all this, is that I
