LGBTQ history dates back to the first recorded instances of same-sex love, diverse gender identities, and sexualities in ancient civilizations, involving the history of lesbian, gay, bisexual, transgender, and queer (LGBTQ) peoples and cultures around the world. We know that homosexuality existed in ancient Israel simply because it is prohibited in the Bible, whereas it flourished between both men and women in Ancient Greece.
Substantial evidence also exists for individuals who lived at least part of their lives as a different gender than assigned at birth. In ancient Mesopotamia, the priests and priestesses of the popular goddess Inanna (better known as Ishtar) were bisexual and transgender. One of the aspects of the goddess considered most awe-inspiring was her ability to turn men into women and women into men, the power of transformation.
Explore the LGBTQ history in the United States and not only, from the gay liberation movement to the fight for equal rights and same-sex marriage. Learn about the milestones of the lesbian, gay, bisexual, transgender, and queer community. Psychologists in the 19th and 20th centuries, most of whom classified homosexuality as a form of mental illness, developed a variety of theories on its origin.
In fact, recent findings indicate that epigenetics operating in utero may be integrally involved in determining the future sexual orientation of the fetus. Thus, the fraternal birth order effect explains only about fifteen to 29 percent of the male homosexual demographic.
It's possible that different mechanisms may be at work in different people. In contrast, older, non-biological brothers step-brothers and adoptive brothers have no effect on sexual orientation, indicating this association is not a result of the family environment during childhood. Furthermore, male homosexuality could help reduce counterproductive competition among male siblings and cousins for female mates.
A society that condemns homosexuality harms itself. Some of the gay person's genetic code is shared with nieces and nephews and so, the theory goes, the genes which code for sexual orientation still get passed down. Paul Vasey, University of Lethbridge. This appears to be mediated via the maternal immune system. Image source, Thinkstock. These results haven't been replicated in some ethnic groups - but that doesn't mean they are wrong with regards to the Italian population in Camperio-Ciani's study.
The two specific SNPs that were most commonly shared among the gay men were in the Xq28 and 8q12 regions, located on the X chromosome and chromosome 8, respectively. We believe sexuality is a highly complex trait, interwoven with sociality. Wilson forty years ago, postulates that the reproductive penalty imposed by homosexuality must be offset by improved chances that the siblings of a gay individual will successfully reproduce and their nieces and nephews will survive.
This would compensate for gay people's lack of reproduction and ensure the continuation of the trait, as non-gay carriers of the gene pass it down. Some researchers believe that to understand the evolution of gay people, we need to look at how they fit into the wider culture. Qazi Rahman says that alleles coding for same sex attraction only explain some of the variety in human sexuality.

The elucidation of the scientific underpinnings of homosexuality will require an interdisciplinary approach using genetics, epigenetics, and evolutionary biology, along with neuroscience, anthropology, psychology, and biomedical sciences. By improving the functionality of the group, gay males could help their siblings reproduce more successfully and improve the viability of their nieces and nephews in harsh ancestral environments.
Home Articles. The U. Image source, Jeantine Mankelow. The first is the effect of fraternal birth order. Height is another feature influenced by hundreds of genes, many of which interact with our external environments in complex ways. The disturbing results of that survey are depicted in Figure 4. Did I care? This game and TLOU2 are saturated with the woke agenda. Societies are mistaken to disapprove of homosexuality because gays have different sexual preferences and reproduce less.
From a mathematical perspective, an individual can achieve the same genetic success by raising one offspring or helping to ensure that a sibling successfully raises two offspring.
