    He was more than a Nanny, he was a "Manny".
    Found it on Friends Wiki:

    Ross and Rachel are looking for a new nanny and Ross is surprised when a male nanny named Sandy has applied. Rachel loves him and despite Ross being uncomfortable with it, allows her to hire him. Sandy is shown to be overly sensitive, crying after they hire him and crying with Rachel when he explains how he propsed to his fiance. He also plays the flute and holds puppet shows. Joey also takes a liking to him. Ross eventually fires him because he's too sensitive but ends up confiding in him after explaining how his dad was tough on him as a kid for playing with dinosaurs instead of sports.



    But even better, I found this. Did you know there is a website where you can find a "manny" in NYC?

As a result they are really streeeeeeetching for subject matter. And it doesn't matter how small the sample used or what the researcher's conclusion is, it seems to pass for science these days.

    I remain convinced that gay parents can be very good parents and sometimes living with gay parents is the best situation for the child. And I will continue to be convinced that there is far more scientific study and evidence to show that children overall thrive best with a loving male AND female role model in the home than in any other circumstance. And the traditional family should be encouraged, supported, and considered the norm for that reason.
    Except this isn't true. There is no research that shows that having both a male and female role model in the house, specifically as the parents, cause children to be better.

    In fact, traditional families would truly be an extended family where many familial role models of both sexes, from either or both sides of the family (either parent) interact with the child/children by living in the house or nearby. This is how my family was raised, with relatives nearby or living with us, and we saw most of them every single day (many of my first cousins I am as close to as siblings). My own sons are being raised like this. They have had an aunt or an uncle living with them for most of their 5-6 years, and other relatives come into and out of their lives, even with two active duty assignments of their parents (one for me when first son born, then last 3 1/2 years for husband). This makes twice now that their grandparents have lived close enough for them to walk to their home. If we set up for/were more friendly to this type of family, the extended family, instead of just the "nuclear family" (which is what people want to claim is the "traditional family"), then there would be more role models in our children's lives anyway. The extended family may not be for everyone, but it is far more traditional (up until the last century or so) than the nuclear family.

    Re: Gay dads' brains show activity akin to both parents': study

    Definitely an interesting article, but I feel it's too short, more research probably would help the case even more. It seemed devoid of something with how tiny it was when tackling so huge an "issue".

    Re: Gay dads' brains show activity akin to both parents': study

    Here's a so called "brain" study that says gay men and heterosexual women have similarly shaped brains. Does this mean that gay men are cognitively equivalent to women?

    Striking similarities between the brains of gay men and straight women have been discovered by neuroscientists, offering fresh evidence that sexual orientation is hardwired into our neural circuitry.

    Scans reveal homosexual men and heterosexual women have symmetrical brains, with the right and left hemispheres almost exactly the same size. Conversely, lesbians and straight men have asymmetrical brains, with the right hemisphere significantly larger than the left.

    Scientists at the prestigious Stockholm Brain Institute in Sweden also found certain brain circuits linked to emotional responses were the same in gay men and straight women.

    The findings, published tomorrow in the US journal Proceedings of the National Academy of Sciences, suggest the biological factors that influence sexual orientation - such as exposure to testosterone in the womb - may also shape the brain's anatomy.

    The study, led by the neurobiologist Ivanka Savic, builds on previous research that has identified differences in spatial and verbal abilities related to sex and sexual orientation. Tests have found gay men and straight women fare better at certain language tasks, while heterosexual men and lesbians tend to have better spatial awareness.

    Savic and her colleague Per Linström took MRI brain scans of 90 volunteers who were divided into four groups of similar ages according to whether they were male, female, heterosexual or homosexual. The scans showed the right side of the brain in heterosexual men was typically 2% larger than the left. Lesbians showed a similar asymmetry, with the right hand side of the brain 1% larger than the left.

    Scans on homosexual men and heterosexual women revealed both sides of the brain were the same size.

    The results could explain a University of London study earlier this year that found gay men and straight women share a poor sense of direction compared with heterosexual men, and were more likely to navigate using landmarks alone.

    The right hand side of the brain dominates spatial capabilities, so may be slightly more developed in heterosexual men and lesbians. An earlier study by the same team found gay men and straight women outperformed lesbians and straight men at tasks designed to test verbal fluency.

    Savic's team has yet to confirm whether the differences in brain shape are responsible for sexual orientation, or are a consequence of it. To find out, they have begun another study to investigate brain symmetry in newborn babies, to see if it can be used to predict their future sexual orientation.

    "These differences might be laid down during brain development in the womb, or they could happen after birth, though it could very likely be a combination of the two," said Savic.

    In another series of tests, Savic and Lindström used a technique called positron emission tomography (PET) to look at brain wiring in a smaller group of volunteers. They found heterosexual women and gay men shared brain circuitry linking a region called the amygdala, which plays a key role in emotional responses, to other parts of the brain.

    The research is part of a larger effort to identify differences between the male and female brain, in the hope they will shed light on why some mental disorders affect men and women differently. For example, major depressive disorders are far more common and persistent in women, while autism is around four times more common in boys than girls.

    "There's a well known uneven sex distribution in the number of psychiatric disorders and trying to understand sex differences, and differences in orientation, may give you a hint of the mechanism underlying these diseases," said Savic.

    I don't think that the studies had looked into the causality. They had only found significant results to the point. But if you are really interested I am sure you will find more in the world wide web.

During that pre-modern medical era, child mortality rates are 40%+ and thus require the nomadic kin groups to produce large numbers of offspring per fertile couple. This requirement causes the group's age to be weighted towards children. The weighting primarily affects the groups' ability to gather food, defend itself from dangers, move through its territory; i.e. survive, due to the large amounts of needy children.

    Suppose then that there is a biological/environmental tendency, eh, 1/20th of the time, to produce a smaller group of individuals that never reproduces. These individuals do not dedicate themselves to child rearing, but rather are open to engage in the activities that the parents/elders of the group cannot handle. They tilt the group's age back towards capable adults. Thus kin groups with this ability to produce non-reproducing individuals have a better chance of flourishing and surviving.

    It's a theory.
    Neat little story.

    The only thing you can conclude from any study of this primitive nature is that our brains appear to be born to adapt.


    What I find striking from this study and any like it though is that these social researchers aren't doing themselves any favors, because showing adaptability whether emotionally or sexually adds to the environmental causation argument for sexuality. I'd like to see this done on young adults without children to compare data.

    No, this is referring to how hormones affect how brain structures develop in utero. This isn't about brain plasticity / learned behavior.
    eg:



    Sexual hormones and the brain: an essential alliance for sexual identity and sexual orientation (2010)

    "The fetal brain develops during the intrauterine period in the male direction through a direct action of testosterone on the developing nerve cells, or in the female direction through the absence of this hormone surge. In this way, our gender identity (the conviction of belonging to the male or female gender) and sexual orientation are programmed or organized into our brain structures when we are still in the womb.
    There is no indication that social environment after birth has an effect on gender identity or sexual orientation."


    Royal College of Psychiatrists
    "Despite almost a century of psychoanalytic and psychological speculation, there is no substantive evidence to support the suggestion that the nature of parenting or early childhood experiences play any role in the formation of a person’s fundamental heterosexual or homosexual orientation. It would appear that sexual orientation is biological in nature, determined by a complex interplay of genetic factors and the early uterine environment."




    Brain scans have provided the most compelling evidence yet that being gay or straight is a biologically fixed trait. (2008)

    The scans reveal that in gay people, key structures of the brain governing emotion, mood, anxiety and aggressiveness resemble those in straight people of the opposite sex.
    "This is the most robust measure so far of cerebral differences between homosexual and heterosexual subjects," she says.

    Previous studies have also shown differences in brain architecture and activity between gay and straight people, but most relied on people's responses to sexuality driven cues that could have been learned, such as rating the attractiveness of male or female faces.

    To get round this, Savic and her colleague, Per Lindström, chose to measure brain parameters likely to have been fixed at birth.

    "That was the whole point of the study, to show parameters that differ, but which couldn't be altered by learning or cognitive processes," says Savic.

    "This study demonstrates that homosexuals of both sexes show strong cross-sex shifts in brain symmetry," says Qazi Rahman, a leading researcher on sexual orientation at Queen Mary college, University of London, UK.

    "The connectivity differences reported in the amygdala are striking."

    "Paradoxically, it's more informative to look at things that have no direct connection with sexual orientation, and that's where this study scores," says Simon LeVay, a prominent US author who in 1991 reported finding differences(pdf) in a part of the brain called the hypothalamus between straight and gay men.
