Before Beta was created, there was animal experimentation. Dogs, cats, monkeys... all subjected to genetic manipulation to enhance brain activity. I don't think I like where this is goin'... Physical enhancements? The life extension technology was given to them, That's all... When Mavon fled, they were turned out into the world. What! They were sterile weren't they? They couldn't mate... could they? ah. Actually yes they could. And they probably have, with strays and each other. CRipes! It's a whole new world.
