The ancient world had no basis of understanding gender as it has been understood in the humanities and social sciences for the past few decades. The term gender had been associated with grammar for most of history and only started to move towards it being a malleable cultural construct in the 1950s and 1960s.

Recombination probably evolved ~ 3 billion years ago as a mechanism of DNA repair; sex evolved ~ 1-2 billion years ago in the early eukaryotes; the reason is unclear but it its likely that it is maintained in the current day by selection. Subsequent evolution and maintenance of sex and recombination.
If you research the etymology of the word gender you discover that the word gender, up until the 1970's in academia, and up until the 2010's in the general populace, had an identical meaning to sex. Gender meant sex.
There are two biological sexes – male and female. Intersex is a term used for disorders of sexual development (DSD). Gender – the roles, behaviours, activities, and attributes that a given society at a given time considers appropriate for men and women to divide labour.
There are many different gender identities, including male, female, transgender, gender neutral, non-binary, agender, pangender, genderqueer, two-spirit, third gender, and all, none or a combination of these.
It was in the 1970s that feminist scholars adopted the term gender as way of distinguishing "socially constructed" aspects of male–female differences (gender) from "biologically determined" aspects (sex).
While many cultures see just man or woman, other cultures have three, five, or more genders. Thus, rather than being universal to biological males, females, or intersex people, each human society uniquely determines the genders and gender roles within it.
Fluid is a form of gender identity or gender expression, rather than a sexual orientation. Fluid relates to how a person identifies themselves internally and presents themselves to the world. A person who is gender fluid may identify as male one day, female the next, both male and female, or neither.
During early development the gonads of the fetus remain undifferentiated; that is, all fetal genitalia are the same and are phenotypically female. After approximately 6 to 7 weeks of gestation, however, the expression of a gene on the Y chromosome induces changes that result in the development of the testes.
Those species that exhibit sexual reproduction have an evolutionary advantage over "cloners" in that there is more diversity in their offspring. This diversity allows the species to adapt more quickly to a changing environment, or to increase its chance of survival in the existing one.
According to the evolutionary viewpoint, gender differences arise because men and women play different reproductive roles (Trivers 1972). Gender differences are hypothesized to develop because of differing parental investment levels.
The parent gave birth to Searyl Atli in November at a friend's home in British Columbia. Kori Doty, who prefers to use the pronoun they, argues that a visual inspection at birth is unable to determine what gender that person will have or identify with later in life.
It is through the gender order of a society that forms or codes of masculinities and femininities are created and recreated, and relations between them are organised. The concept of the gender order was first developed by Jill Matthews (1984), in her study of the historical construction of femininity.
For many cultures, however, the idea of non-binary genders — someone who doesn't identify strictly male or female —the concept is not as hard to grasp. Indigenous cultures in regions from Oaxaca State, Mexico to Samoa and Madagascar have accepted the idea of the “third gender” for centuries.
Intersex variations are not abnormal and should not be seen as 'birth defects'; they are natural biological variations and occur in up to 1.7 per cent of all births. Most people with intersex variations are not born with atypical genitalia, however this is common for certain intersex variations.
Clam shrimp have a male as well as two varieties of hermaphrodite, which either self-fertilize or mate with males but cannot mate with each other. The protozoan Tetrahymena thermophila has seven distinct "sexes" that can hook up and swap genes (See here).
So no, a hermaphrodite is not a separate gender. A hermaphrodite is both male and female, they are both genders and sexes. Can a hermaphrodite have both working parts? Indeed, true hermaphroditism allows the full function of the reproductive organisms.
As one of the most influential parts of culture, gender roles define how men and women behave and interact with each other. During the 1950s, gender roles dictated that men were the head of the household and the sole provider, while women were expected to be the homemaker who cared for the children.
Gender dysphoria occurs when there is a conflict between the sex you were assigned at birth and the gender with which you identify. This can create significant distress and can make you feel uncomfortable in your body. People with gender dysphoria may want to change the way that they express their gender.
Publication history. Gender Trouble was first published by Routledge in 1990. Later that decade, a second edition was published by Routledge.
Tetrahymena thermophila is a single cell covered with a coat of hairs called cilia. The cilia wave back and forth, powering it through the water. Its seven sexes are rather prosaically named I, II, III, IV, V, VI and VII.
Scientists have known since the late 1930s that the protozoan Tetrahymena thermophila can belong to any of seven sexual reproductive groups, or 'mating types'. Each mating type can reproduce with any of the other six, but not with its own type.
Sex as well as gender
Sex refers to biological attributes that distinguish organisms as male, female, intersex and hermaphrodite. Gender is a social construct, encompassing various psychological and social characteristics that collectively define individuals as men, women, non-binary or trans3,10.
