Aug 29, 2019 · Analysis of half a million people suggests genetics may have a limited contribution to sexual orientation. Few aspects of human biology are as complex—or politically fraught—as sexual ...
Aug 14, 2024 · Researchers assessed many thousands of different molecules in people from age 25 to 75, as well as their microbiomes — the bacteria, viruses and fungi that live inside us and on our skin — and found that the abundance of most molecules and microbes do not shift in a gradual, chronological fashion.
- The Hunt For ‘Gay Genes’
- How Might These Genes Influence Same-Sex Behavior?
- Why Does Homosexual Behavior Exist?
The new finding is consistent with multiple earlier studies of twins that indicated same-sex attraction is a heritable trait. The 2019 study is the latest in a hunt for “gay genes” that began in 1993, when Dean Hamer linked male homosexuality to a section of the X chromosome. As the ease and affordability of genome sequencing increased, additional ...
I find it intriguing that some of the genes from men identified in Ganna’s study are associated with olfactory systems, a finding that has parallels to the work in mice. Ganna’s group found other gene variants that may be linked with sex hormone regulation, which other scientists have previously suggested plays a large role in shaping the brain in ...
Several hypotheses have been advanced to explain how homosexuality can be beneficial in perpetuating familial genes. One idea involves the concept of kin selection, whereby people work to ensure the passage of their family’s genes into subsequent generations. Gay uncles and aunts, for example, are “helpers in the nest” that help raise other family ...
