You are human.

What is a human?

A human is an organization of energy developed by evolution.
— human

Here is an example demonstrating how a human is defined by evolution.

This example asserts, 
    "A human is defined by the traits of humans who reproduce over time"
     because
     humans are developed 
         by evolution
         by reproducing over time.

--- Evolution of a Human

You are a human, 
    with similar traits to your parents, 
    who have similar traits to their parents,
    so on and so forth...

The distinct traits of humans in your parents' generation who did not reproduce
    do not exist 
    in the current generation of humans.

So, the traits of a "current generation human"
     includes
         the genetic traits of their parents 
         and 
         the mutated traits of the "current generation human"
      but not
          the genetic traits of the humans who did not reproduce.

--- Definition of a Human: Sex

Suppose you observe humans reproduce due to their sexual urges.

So, you define a human as
    "an organization of energy which has a sexual urge" 
    since
    a "sexual urge" is "a trait of humans who reproduced over time".

This observation distinguishes 
    a human
    from 
    "any other organization of energy" 
     by defining 
         a human 
         as 
         "an organization of energy with a sexual urge".

--- Definition of a Human: Other Traits

Suppose you observe other traits which distinguish a "human" from another "organization of energy". 

You can define a human by these observed traits, which are "the traits of humans who reproduce over time".

So, a human is defined by "the traits of humans who reproduce over time".

How does a human behave?

A human acts based on emotion to reproduce.

Here is an example demonstrating how a human acts in a hunter-gatherer tribe.

You are human in a hunter-gatherer tribe.

Here is an example demonstrating how a human acts in an agricultural tribe.

Here is an example demonstrating how a human acts in a megacity.

Suppose you cannot act on your emotion.

The world dominates you.

Here is an example of domination in the world.

Suppose there is a lion and a gazelle.
	- The lion feels hungry.
	- The pregnant gazelle feels hungry.

Each animal searches for food in the world.
    - The lion sees the gazelle and moves towards it.
    - The pregnant gazelle eats grass in an open field.

Suppose the gazelle runs from the lion.
     - The lion's hunger is dominated by the world,              
         because the gazelle escaped.

     - The gazelle's hunger may be dominated by the world, 
          because 
              the lion made the gazelle stop eating 
              and 
              use energy to run away.

      - The gazelle's baby (in the womb) is not dominated, 
           because it exists in the world.

Suppose the gazelle is shocked into birth before running from the lion.
     - The lion's hunger has dominated the gazelle's reproductive efforts by eating the baby gazelle.

     - The lion's hunger may be dominated by the world,
         because the adult gazelle escaped,
         and eating the baby gazelle did not give the lion enough energy to execute the lion's hunger.

     The gazelle's hunger may be dominated by the world,
         because the lion made the gazelle stop eating 
        and spend energy to run away.
