To test the theory, Joel and her colleagues looked for differences in brain scans taken from 1400 people aged between 13 and 85. The team looked for variations in the size of brain regions as well as the connections between them. In total, the group identified 29 brain regions that generally seem to be different sizes in self-identified males and females. These include the hippocampus, which is involved in memory, and the inferior frontal gyrus, which is thought to play a role in risk aversion.
When the group looked at each individual brain scan, however, they found that very few people had all of the brain features they might be expected to have, based on their sex. Across the sample, between 0 and 8 per cent of people had “all-male” or “all-female” brains, depending on the definition. “Most people are in the middle,” says Joel.
This means that, averaged across many people, sex differences in brain structure do exist, but an individual brain is likely to be just that: individual, with a mix of features. “There are not two types of brain,” says Joel.

I feel the truth is somewhere in the middle. I understand that culture has a way of becoming invisible, to where even open minded parents may not realize they are influencing a gender binary upon their toddlers (there was a study on this actually.) So it may be impossible to ever to study a baby human's predilections in an environment removed of cultural influence and thus gender binary. These binaries also may become a source of persecution to people. So this is an important topic in trying to set up a more enlightened human culture.

Multiple Genders have existed throughout various cultures and were not only recognized but celebrated and seen as Special and Gifted. not "Mental Defects" or ""Illness"
Ragini Verma, a researcher at the University of Pennsylvania, said the greatest surprise was how much the findings supported old stereotypes, with men's brains apparently wired more for perception and co-ordinated actions, and women's for social skills and memory, making them better equipped for multitasking.
.....The results establish that male brains are optimized for intrahemispheric and female brains for interhemispheric communication. The developmental trajectories of males and females separate at a young age, demonstrating wide differences during adolescence and adulthood. The observations suggest that male brains are structured to facilitate connectivity between perception and coordinated action, whereas female brains are designed to facilitate communication between analytical and intuitive processing modes.

This quote stood out to me from the recent article:
Although the team only looked at brain structure, and not function, their findings suggest that we all lie along a continuum of what are traditionally viewed as male and female characteristics. “The study is very helpful in providing biological support for something that we’ve known for some time – that gender isn’t binary,” says Meg John Barker, a psychologist at the Open University in Milton Keynes, UK.
The findings will still come as a surprise to many, including scientists, says Bruce McEwen at the Rockefeller University in New York. “We are beginning to realise the complexity of what we have traditionally understood to be ‘male’ and ‘female’, and this study is the first step in that direction,” he says. “I think it will change peoples’ minds.”
Genderless future
Joel envisions a future in which individuals are not so routinely classified based on gender alone. “We separate girls and boys, men and women all the time,” she says. “It’s wrong, not just politically, but scientifically – everyone is different.”
Joel’s findings can be used to help many people understand the non-binary nature of gender, says Barker. After all, some people don’t identify as either male or female, and others feel their gender identity shift over time. “It’s a shame that people’s experience alone isn’t enough for us to recognise as a society that non-binary gender is legitimate.”
“We need to start thinking a lot more carefully about how much weight we give to gender as a defining feature of human beings, and stop asking for it in situations where it simply isn’t relevant,” says Barker.
So I guess that means no queer brains either?
Perhaps it takes a queer brain to publish a study like this.
What do you say, ATS, is gender binary, or not?
Only Yes or No will accepted as an answer =)
The really weird thing to me is that I feel like this is the twice-baked version of the women's lib movement in the '60s and '70s all over again, arguing about what a man or woman "really" is, when in the end, we're just people -- the same and different all at the same time.

i thought gender was what you had between your legs, not what you felt you identified as. genetically speaking arent the only genders male, female, and hermaphrodite?

No, Gender is not Binary, the West are the ones who created a two Gender Binary systemcreated a two Gender Binary system
Really ? I thought evolution did that .Just damn . You have destroyed all my scientific knowledge with one small post..
Question then. If evolution is perfect what about the intersexed hermaphorites? Woudnt if it was a Evolutionary imperative there would not be any of those?
You , yourself know the answer to that...(if you know anything about genetics) and you misspelled that horribly.
Well if everyone was able to be a breeding pair the world would be over populated and could be natural to reduce breedable pairs. but they are technically a third SEX because they have both organs.

i dont care what you identify as but the labels man and woman are there for a reason. no one should ever be ashamed about being a man or a woman even if they dont identify as their actual sex. why would anyone care about someone else's opinion anyways?
