Multi-cellular living organism who can move (unlike plants
), consume other organisms and who can respond to stimuli from its environnement and who sometimes is able to use tools and even computers.
Wrongly considered to be majorly different from humans
, as in reality there is no real border between humans, since the history of humanity shows many species going from commonly-considered animals to the modern man, without any real break in the evolution that would show a border between animals and humans.
Animals are often considered less than what they really are (such as walking-food) and many humans feel insulted when recalled they are animals as indeed it should rather be animals who should feel insulted for being considered so much lower than humans.
Hmmmm...well if we're not supposed to eat the animals, then how come they are made out of meat? (now replace "animals" by "humans" and see how it keeps the same meaning)
