       | Throughout the history of biology, psychology, cognitive science,
       | and neurosciences, there has been a constant back and forth
       | between those who would exaggerate sex differences, and those who
       | would understate sex-differences as purely social constructs with
       | no affect on biology other than what is caused via experienced
       | socializations. The truth is more complicated than any of those
       | extremes.
       | 
       | Important differences in biology exist at every level of
       | description, from molecular pathways to large scale brain
       | morphology, and yet! The differences by sex are often subtle, and
       | heterogenous, and not consistent across species. Nevertheless,
       | while the sex chromosomes have far-reaching effects on
       | development, starting at the very beginning of the
       | neurodevelopmental timeline of cell proliferation and migration,
       | the formation and structure of synapses, and so on, its not the
       | whole story.
       | 
       | A too common way people differentiate sex from gender is to say
       | that there is, on the one hand, biological sex, which they'll add
       | is both real, binary, and unchangeable, and then there is gender,
       | the infinitely mind-bending social construct. This framework is
       | often draped with an aura of scientific impartiality. I want to
       | stress to you that this framework is not scientifically
       | justified. Not at all. Further it is patently harmful and
       | trivialized the very real phenomenon of gender diversity.
       | 
       | First, biological sex is not the same thing as chromosomal sex.
       | The sex chromosomes only partially, and only indirectly influence
       | physiological and brain development. Development is fundamentally
       | a multilevel process integrating genetic, epigenetic,
       | environmental, and experiential factors, all of which can lead to
       | qualitative and quantitative differences in the expression of the
       | sex phenotype. Differences in the timing and dosage of steroid
       | exposures within an individual, can lead to any particular
       | feature being more stereotypically masculine, feminine,
       | androgenous, or other phenotype altogether. The result is a
       | mosaic of features with high degree of overlap in those with XX
       | and XY chromosomes.
       | 
       | Sometimes this kind of effect pushes someone's actual attributes
       | to be not as typical of their chromosomal sex. These traits in
       | turn will influence the gender identity they feel most in tune
       | with, and how they incorporate and react to the socialization of
       | gender norms.

           | 
           | Also these dismissals using 'but most people' are ironic; the

             | It is fundamentally different.
             | 
             | The range of behaviors that Humans have is fundamentally
             | far, far more broad than animals, because we are much more
             | intelligent creatures. Example from a few thousand years
             | ago: Farming, Cooking food. More recent examples: Fixing
             | cars, doing taxes. Most of what Humans spend their time
             | doing these days are things that animals don't do in
             | nature.
             | 
             | Human cultures like to ascribe gender roles to most of
             | these things, but in reality most of what people do doesn't
             | have any implicit gender role associated with it, since
             | it's pretty far removed from biological functions at this
             | point.
             | 
             | Even in nature, the things people and animals do doesn't
             | always neatly align with gender roles. For example, child
             | rearing or even bearing live young is sometimes done by the
             | male, even though it's usually a female gender role.
             | 
             | What's different between us and animals (as is usually the
             | case) is our big thinky brains, and the things which follow
