         | Most uneducated people in the world can tell you that there are
         | many traits which distinguish people from animals: religion,
         | our souls, our ability to learn about the world around us, the
         | fact that we act on reason and not on instinct, our ability to
         | read and write, etc. It's perhaps one of the most obvious

         | beings on Earth.
         | 
         | But with enough fancy words and misapplied education, you can
         | say things like "Oh Elephants have burials too, so human beings
         | aren't special, we're just wild purposeless animals also. Only
         | silly religious people think humans are special"

         | There are a number of traits that make humans a unique animal,
         | it's not a misconception.
         | 
         | Humans:
         | 
         | - Are aware of the existence of good and evil and have the
         | capacity for moral reasoning
         | 
         | - Have language
         | 
         | - Are aware of the existence of the distant future, and can
         | plan for it beyond the instinctual cycle of a single season
         | like a hibernating squirrel
         | 
         | - Are aware of their own mortality and vulnerability
         | 
         | - Have art
         | 
         | There might be more but that's a good start. We are animals, of
         | course, nothing "separates us from the animals," in a clean
         | way, but boy we're weird animals.

               | and apply it to an encounter in the forest between a
               | human and a venomous snake.
               | 
               | Imagine one kills the other without provocation.

               | 
               | 1. The human was your pregnant wife.
               | 
               | 2. The human was the mass murderer, Adolf X.
               | 
               | 3. The snake was hungry and scared, and had a family to
               | care for.

               | Not all people share the same moral code, but we do

           | Pretty much everything else derived from these innovations,

             | 
             | The theory is that there is a mutation which caused the jaw
             | muscle of the line of hominids that gave rise to humans. If
             | you look at chimpanzees, gorillas, and other hominids
             | you'll find a skull with a crest with the anchor point for
             | the muscle that enables a very powerful jaw. However, that
             | muscle also constricts the size of the cranium which
             | likewise constricts the size of the brain.
             | 
             | The theory goes that by weakening this muscle it allowed
             | for other mutations to increases the size of the cranium
             | and at the same time necessitated the use of fire and tools
             | to help overcome the "we can't kill it by biting it."
             | 
             | That mutation traces back to about 2.4 Mya. Earliest hints
             | of control of fire was about 2.0 Mya. The Oldowan tools
             | date to 2.6 - 1.7 Mya.
