"God created man and woman different and assigned each of them their own purpose. That's the natural order of things. It's no use to question it."

"No more dogma!"

"Booo!"

"Men and women don't have the same interests and occupations because they evolved differently. It's scientific."

"No, it isn't."

"Don't question science."

Evolution

"Let's attack those across the river! They're demons!"

EVOLUTION

"We will not see the essence of our country polluted by foreign influences that people with values different from our own are intent on bringing onto our soil!"

"To rule out any cultural bias, the experiment was repeated in several cities around the world. In every case, most people correctly identified the picture."

"What is the conclusion?"

"Batman is determined evolutionarily."

"With all this taking care of the young business, they are born less and less capable of fending for themselves. If we keep on getting weaker, beasts will eventually get the better of us for good."
