It's like people need a mass design. :) I don't know if this will happen by decreasing or increasing the number of chromosomes. Problems arise because of people's damned small egos. Not everyone is the same, and they don't have to think like us. We differ in many ways, from appearance to education to parenting. After all, everyone is different. As long as people don't have more respect and tolerance for one another, the problems will continue.
