Starting from the point of view that human same-sex attraction is an evolutionary paradox, Andrew Barron, a neuroethologist, argues that this is only true if we look at the population as divided into two groups – people who are exclusively straight and people who are exclusively gay.
Every study into human sexuality confirms that people are on a spectrum. A majority identify as exclusively straight, a minority identify as exclusively gay and the rest are somewhere in the middle. As Barron says, this means that ‘we should be asking how variation in sexuality evolved, not just how same-sex attraction has evolved’.
The same is true for tallness or intelligence. People are on a spectrum. In addition, other areas of our life could be viewed in a similar light. For example, mental health. Perhaps were are too clinical in our diagnoses. Perhaps mental health is spectral too.
And what about race? Given that the whole human race may have evolved from the African continent, isn’t it nearer the truth to consider that race is on a spectrum too and far from trying to separate human beings into different racial compartments, we should acknowledge that we are all too closely related to be too different!
And what about the spectrum of faith. We do have people who identify very strongly with a particular faith and there are others at the opposite end of the spectrum who deny the truth of any faith. And most of us are probably somewhere in the middle of the spectrum torn between, ‘Jesus is Lord!’ and ‘Where is God?’
