People have always hypothesized about aliens having brains that squish out the tops of their heads. With function capacity evolving to levels of telepathy and other outrages things.
But, today I was reading an article somewhere that suggested human primates may not have always been as emotionally inclined as they are now, and this got me to thinking...
What would the evolution of emotion consist of, (I personally am anticipating the end of the world)?
Such a scary thought.
