Evolution
Evolution has come a long way since the beginning of time. Homo sapiens have been roaming the earth and evolving mentally for hundreds of years now. It was time for a huge leap forward in human development.
Mutants, like me, are humans in the extreme form. Our senses were better than any animal native to this earth. On average we live about two hundred years, so they're predicting. The best thing about being a mutant was the powers that came with it. Each mutant was gifted with a power so specific to that mutant that no other had that exact power. Some even had multiple.
A mutant's power could manifest at anytime between eleven and sixteen. At sixteen a government sector in charge of keeping track of all mutants, came to classify your powers by Unos, Delta, Omega, Beta and Alpha and then it subdivided down into strength. Of course your powers could increase with schooling but most mutants were satisfied with what they had or just decided to integrate into the human world.
When mutants finally decided to show themselves to humans, the world changed drastically. I was only six but I could remember certain things. Like protesters trying to force us back into hiding. Or worse. The news was filled with hateful acts from humans and mutants alike to stubborn to accept each other. Most mutants decided to protect themselves and built their own mutant villages. Some of the more stubborn, human hating, mutants, holed up in these mutant villages as well. Ten years after coming out, it was a normal thing to see mutants and humans together. Smaller towns still had their prejudices but it was nothing like the first year.
