oh....I just can't believe it!Many of those people who got the disease not only afflicted,but also have reduced reproductive fitness.Critically,Evolution May Favor Schizophrenia Genes !What we should do for those people??

Schizophrenia is surely unhappy to everyone.Below is my some understanding.
1.the Schizophrenia related genes enable us gain the talent such as language,logic, and sensation.However,after some million years evolution,we,human,is at the top of evolution peak.In another word,our genetic is too complex so taht some little gene problem may induce disorder.
2.the majority who have not been Schizophrenia,I think,the Schizophrenia related genes is balanced.I means someone have the Schizophrenia related genes ,but he can be healthy.

"In recent years," those are the words that jump out at me from the writeup. "In recent years." Does this mean that the selection forces weren't there before the industrial revolution or only that they only studied what they could reach? What has changed over time that makes schizophrenia genes valuable?
