In order to be able to dominate someone, it is necessary for people to be dependent on each other. To have power over another means that that power is relative and not an absolute property. We can see from this dependence that power is primarily one arising out of man's social nature, rather than an individualistic one to compete. The mutual dependence of people necessitates forms of social organization. Competition is therefore not the primary mode of human existence, but is a secondary one arising from socially conditioned institutions.
But you must ask yourself why those modes of social organization arose in the first place? Where does the urge to dominate others stem from, if not biology? Obviously social dominance behavior is very widespread throughout the animal kingdom. So it's not enough to simply wave it away by saying that it arises from social conditions.
Whilst there are no doubt biological differences between the genders, it does not follow that these entail differences in gender roles in which a man is dominant and a woman is submissive. This idea of gender roles is often expressed in our conceptions of masculinity.
Again, you have to ask what caused those social conditions to arise in the first place, if not for biological reasons. Testosterone is linked to aggression, confidence, confrontation and violence. Estrogen are not associated with any of those behaviors. (Actually, estrogen is correlated with depression, although males commit suicide at a higher rate even women attempt it more, due to them choosing more violence methods such as guns.) This all goes back to primate mating strategies, where the male must out-compete the other males in order to secure a chance of reproducing. The habit of males to compete with other males for the female's attention through mating displays and eye-catching behavior is a part of this. Then, once he has her and she has given birth, the male has to defend both her and his young from predators. So the male as the leader and protector has a very long evolutionary history in our family tree. I do not see how this is something that humans just "made up" at some point out of sadism.
Importantly, there is a common perception that male homosexuals are submissive, where as male heterosexuality demonstrates dominance. Dominance is not therefore an inherent or biological trait of men due to testosterone as this contradicts the common notion of masculinity which is often homophobic. Nor does this view take into account the existence of the "third gender" whose members are biologically neither male nor female. The submissiveness of homosexual men and of women, the social exclusion of the third gender and the assumed dominance of heterosexual men is down to their social function in a patriarchal and heterosexual order in which they are conditioned to accept male and heterosexual dominance.
Of course, most gay men are not effeminate. I'm actually not sure what causes some males to be effeminate or some women to be masculine (although masculinity in women has been linked to them having higher than average testosterone, at least in some cases, so maybe there's something similar going on with effeminate males but the other way around; I'm not aware of any studies on the hormonal makeup of specifically effeminate males, however). In the gay context, it seems to be a mimicry of heterosexual relationships, particularly in the lesbian butch/femme culture.
Biologically speaking, there is no such thing as a "third gender". There are various intersex conditions which result from chromosomal and hormonal abnormalities, however (and I would include transsexualism in that category). As I mentioned, effeminate males and masculine women may have hormonal abnormalities. More research has to be done on that. But science is showing more and more that sex behavior differences are largely the result of biology and not social conditioning, as Marxism would have us to believe. (Note that I'm not saying this a good or bad thing, it just is. I'm actually a transsexual, myself, and the scientific findings on it actually make our fight for understanding more grounded than if it was just some social construct mess.)
For the sake of brevity, I will say only that the family institution is a product of the division of labor between men and women and is the result of specialization of genders to engage in specific forms of activity; men are presumed to be engaged in "productive" labour as the 'bread-winners' and women are engaged in "re-productive" labour concerning children and related domestic tasks. This division of labour is then established as legal and moral norms of behavior. The family structure is not the result of biological differences in gender, but of the necessity of reproducing property relations based on exploitation.
Actually, for most of human history, humans have lived in smaller, family-oriented groups within clans and tribes. Both sexes would mostly stay at home and do things around the house. However, hunting was mostly something that males did. There is a theory that males did the hunting more to show off their abilities to prospective mates.
The so-called "nuclear family" is a concept that mostly emerged in the post-WWII years and is pretty much a bastardization or distortion of primal instincts merged with modern Western individualism.
You can read more about where this is rooted in our evolution here:

This is not exclusive to capitalism, as the necessity of owning property means it is necessary that people are treated as property in legal entities, and therefore the institution of "marriage" and "inheritance" act as way to ensure property is re-produced, along with conditioning the moral and psychological attributes of existing society in the next generation.
But what is the root of that? Marriage, as I understand, began as a way to ensure paternity, stability and inheritance for quite pragmatic means.
As this is a scientific question, it is necessary for me to demonstrate that whilst there is evidence of dominance, it does not necessarily follow that that is the product of biology, such as levels of testosterone in men. it is Hypothetically possible that Testostorne levels are the effect of social relations rather than the cause.
So now you're doing the chicken or the egg argument, eh? You still are failing to show how those social behaviors came to be if they are not biologically driven. That they are biologically driven has a wealth of scientific information to back it up from a multitude of fields. You are basically asking me to ignore science.
Nature does not abide solely by a law of the Survival of the Fittest. There is well-documented evidence of social behavior amongst animals, whether it is social insects (ants, bees, wasps, etc), as well as social animals, such as lions and wolves. Whilst these may be organized by power structures, these are secondary to their social organism; rather than have evolved and adapted social organization as a superior method of attaining subsistence. Working together necessarily gives them an edge in getting resources.
Of course humans are a social species. We would not have survived if we weren't. Psychopaths, for example, are an evolutionary aberration because they do not possess the social instincts that normal humans do. They are evolutionary failures, if you will. But while we are a social species that tends to cooperate in general, we still do have an innate urge to compete with each other and this is rooted in the urge to ensure the survival of our lineages.
Hence, we can say that the existence of individual status and social organization are not independent of one another. The question therefore is which is more important; the competition for social status and therefore attributions of social dominance, or the existence of social organization itself. If it is the latter, then it is possible to a social organization without (or with greatly diminished) hierarchical power structures where one person dominates another.
But I say this is impossible. Even in Marxist states, the ruling elites still competed with and backstabbed each other. In Fascism, there is a middle way by allowing humanity's natural instincts to compete and dominate to be exercised in a controlled way for the benefit of the Nation as a whole. Systems such as Libertarianism and Communism both fail in that they both go too far to the extremes. Libertarianism basically ignores and disdains humanity's social nature and Communism tries to erase the innate impetus for personal excellence. (Fascism is tied into meritocracy. It's similar to a monarchy without basis in heredity. It encourages human excellence and the most deserving people to rise to the fore.)
The study cites the relationship between dominance and aggression both in animals and in humans. If the existence of society was dependent on natural dominance, it would mean that such dominance could only be achieved by coercing people into those relationships. Hence dominance could not exist without aggressiveness. That is not the case as is evident by liberal institutions as well as the fact that human beings cannot live (at least for very long) in isolation; they must necessarily be part of the group. social organization is an evolved response to an economic problem. Social dominance is therefore the response to the scarcity of resources and the need to distribute them amongst people. As such, dominance is not inherent.
Even when people are happy and have resources, they still participate in displays of dominance and aggression. Look at sports such as boxing, wrestling, rugby, hockey and American football. Obviously there is something innate here that needs an outlet.
[there were a lot of sources, so I had a go trying to respond to the first one].
No problem. Sorry for flooding you.
The urge to dominate others is not biological in foundation but is the result of economic relations in society and the psychological conditions of its members to work within that organization. However, it is attributed to biology because the changefulness of human social relations is ignored in formulating legal and moral views of society. the capacity for change is therefore excluded from view when these power relations are attributed to "natural" causes rather than environmental or socio-economic ones.
You will have to provide empirical evidence for that bold claim. The only way I can see that being true is if we somehow transcended our biology.
