Communal society is as much a part of our genetic inheritance as competition is, which means unfettered markets may be more an invention of culture than an expression of our underlying biology. Their worldview has them reaching for a revolver at any mention of human nature.So there's no reason to object to tinkering with our DNA or hacking our gray matter. There is no single gene responsible for a person being gay or a lesbian.STARTScience is pulling the long-standing debate in strange directions. If you rose to the pinnacle of society or sunk to its depths, you had only yourself to thank or condemn.Ever since Hobbes and Rousseau started riffing on the state of nature and the noble savage a few centuries back, the nature versus nurture debate has been as much about politics as empirical research. Society, much less big government, couldn't change your fate.Of course, ethical concerns arise with any attempt to use biology to explain complex human behavior like sexuality.For instance, Bailey added, there is no evidence that things like conversion therapy work.Yet green politics is predicated on the sanctity of the natural world as evolution shaped it.So why shouldn't humans have their own innate nature?The political landscape is splintering into ever more precise ideological niches, even as technology and science muddy the nature-nurture waters.Knee-jerk reactions just aren't what they used to be.
