The term Biofamily can be considered a necessary neologism for studies and research about the family. This, with its customs and behaviors also acquires interest from ethics. From the ethics applied to the family the term biofamily arises, which refers to the first life group, where the person becomes human. Globalization has allowed the entry of ideologies that take the natural family from its rightful place; public policies must consider the structure and functioning of the biofamily as the foundation for the development of society. The relativization of the family concept by supranational organizations has contributed to increased confusion. The development of the concept of biofamily, in academic and research environments will allow not to distort the concept of family.

From the sexed nature of human beings, much has been said about the dominance of one sex over the other. Faced with this, the terms patriarchy and matriarchy arise not necessarily in that order, such as force, dominance or control over the other.The historical evidence recognizes the actions of women in public positions within prehistoric society to the point of using the term matriarchy, which fades in the Neolithic with the consolidation of sedentary life, and in the nascent social organization it is the male who exercises authority as head of the family, giving rise to the patriarchy.It is in the nineteenth century that the first feminist movements were born to later take up the debate on patriarchy whose theorization, from different perspectives, has given rise to different currents of feminism, each with a particular vision of female identity.
