What Makes Us Human? It’s All about Sex! Part 1

One of the biggest questions in evolution, and one of the biggest challenges thrown at materialists by believers in a creator, is what makes human’s different from other animals and how can these be explained by natural processes? Over the next two posts I will discuss the works of Geoffrey Miller, who has come up with an overwhelmingly strong answer. Here I give an overview of his first book The Mating Mind: How Sexual Choice Shaped the Evolution of Human Nature where he sets out the theory of how we have come to be what we are.

In the follow up I will discuss his second book Must-Have, which explores what this means for modern society and I will look at what these theories mean for my philosophy of Spiritual Materialism. If I have done Miller’s central tenets any justice in my two unfairly brief summaries you will hopefully be as convinced of their merits as very strong scientific theories for their ability to explain so much of what we see, without conflicting with what we know, about human psychology and evolution, and making a vast number of testable predictions. Unfortunately I don’t have the space to present the evidence Miller does for his proposals, you will have to refer to the original works for that.

(There is also a healthy amount of educated speculation based on what we do know, both from myself and Miller, this is included to spark discussion rather than because I am convinced of their certainty.)

Miller’s first wide reaching theory sets out to explain what we see as our uniquely human mental traits (and one or two physical ones too) and thereby very thoroughly covers almost all male and female desires, intentions, interactions and differences. The crux of his theory is that those uniquely human mental qualities; academic intelligence, reasoning, artistic abilities, empathy, humour and ideology, may have developed through evolution of sexually selected traits.
