The Shirahime
...It took you awhile to look that one up, dragons and Giant snakes are both myths that are in every society.
Actually, dragons vary widely from place to place (when was the last time a European Dragon brought good luck to someone?) and snakes, as an animal, are found almost everywhere.
The myths are only the same if you squint and don't look at them too closely.
The Shirahime
Thousands of animals have become extinct because of us, so we can take into account that the theory that once was accepted is useless now.
You know that species becoming extinct supports evolutionary theory, right? So does the fact that pig and ape organs can be grafted into humans and will work properly, and that things can be tested on animals with the results applied to humans.
