Discourse on human nature tends to focus on those natural characteristics which appear to distinguish humans from other forms of life. The general theme is usually anthropocentric and goes something like “that which makes us different is that which defines our humanity.” While comparing differences is informative in some contexts, it is an exercise that is too often undertaken as a means to demonstrate a special, preordained standing in nature for mankind and moral supremacy. In fact, the essence of human nature is not that which sets us apart from or above other forms of life, but those characteristics which we share in a common evolutionary history.
It is along this continuum that core human operational modules — such as survival, socialization, and the pursuit of happiness — have developed by natural selection. Thus, it is from the broad perspective of unity and inclusion that human nature is best described and from which an understanding of morality may be gained.
