During the course of human history, many questions have been raised about the somewhat different behaviors each sex demonstrates. From a 1992 edition of the Texas Monthly, Lawrence Wright mentions that "unlike women who carry two x chromosomes, men have an X and a Y. Biological concerns have been one of the main questions dealing with behavioral characteristics in both the man and the woman." Wright also refers to the possibility that one sex, particularly the female, has an advantage because of the genetic makeup it contains.
The human genome is sometimes referred to as a "map." Genetics, in a sense, determines how an individual will turn out, but of course the environment to which one was exposed determines how the genetic makeup comes into play. On the behavioral side of things, these traits can be determined biologically and environmentally. A book published by the National Academy of Sciences (NAS), explains that until recently the popular focus on behavior primarily centered on the environment in which one was raised. In more recent years, they explain that genetic and physiological differences have also come into play as being another answer for what influences and determines the behavioral differences between sexes. Experts of this field also recognize that within a general environment there are also what some refer to as sub-environments which are different social groups in which one may reside. This in turn can also determine different behaviors. When alone, humans usually exhibit different behaviors than if they were at a social gathering or event. Most of the time, humans act accordingly to the specific environment that surrounds them.
Men and women, however, can be seen to have many different specific behavioral traits associated with them. When generally identifying men, John Updike writes about how they can be considered a "disposable rocket." Men are sort of like a disposable delivery system which, after procreation takes place and is final, can typically be "thrown away.
