True but that does not invalidate the original behavior which developed before candles were invented.Originally Posted by battybattybats
The human species diversified over the globe 50,000 years ago. So any genetic basis for gender must have developed a long time ago well before any recognizable society or knowledge existed.Or often a few generations depending on if all the species carry the gene or just a few.
Absolutely! the genuine TG role that exists throughout the Pacific Island societies is as good an example you will ever find that gender is not genetic or preordained. Gender can and is controlled by one's surroundings and so it is actually straightforward to mold a child's gender identity so long as society approves of this role allowing it to peacefully exist with prejudice.The people of Samoa did not have metal technology untill recently. Yet they had and still have crossdressers as a 'third sex' that function well in the society. They are often a males first sexual experience, they do a great deal of housework and child rearing.
Contrary to what is believed in the West there can be as many types of gender as society dreams up.
But nowhere is there evidence for a gene that acts like a switch between masculine and feminine gender. This is impossible since the definitions of gender except for the sexual roles are created by society.Very much not so!
Not every human has the same genes for starters.
But when a cell dies its linkages are broken. These linkages can be regrown if the behaviors are repeated.But the pattern, placement and associations of those cells, the positions and attachments of axons and dendrites shift very little except in certain circumstances.
I think you are looking down the telescope the wrong way around. The brain is like any other part of the body in that it responds to the individuals needs. So if we exercise a certain part of it by doing a certain behavior then that part will grow with more cells and more linkages. It is not genes which grows certain parts bigger but behavior which induces growth in exactly the same way a muscle grows upon exercise. The key then is a person's personality and how this personality interacts with the surroundings.But certain parts of the brain are related to specific behaviours. And neurotransmitter levels in those parts of the brain effect their functioning. And genes are part of brain development and neurotransmitter levels and hormone function etc etc all of which do effect behaviour.
Some behaviors are instinctive though for survival and should not be confused with learned behaviors which must adapt to the society the person is born into.Remember were not just talking about behaviourisms, like the skill for walking or throwing a basketball, but in behaviour drives like hunger and the desire for sex.
Only for genetic defects.Schizophrnia et al says otherwise.
This would only be relevant if there was a gender gene. There isn't.That is because events in life switch different genes on and off, and the switch of the gene can then be passed on to the next generation!
Except that in the case of identical twins it is actually very easy to trace. Overwhelmingly identical twins do not share behaviors like being transgendered or being gay. If either behavior was based in genetics we would see 100% (or close to) match in identical twins. We have a ready made scientific experiment which proves these types of behavior have no genetic basis. This easily trumps all other anecdotal evidence and until it can be explained why genetic clones do not share the same TG behavior then everything else is essentially mute.When in the closet it is hard to trace.
I would disagree, so far this is all disputed speculation based on tiny unscientific sampling or animal experiments. None of these theories have been endorsed by the scientific community. That does not automatically mean it is wrong but a lot more data needs to be gathered and large gaping holes in reasoning closed before any of these theories can be taken seriously.There have been genes found related to TS
