E arly last year, a mother-of-four in the Pacific nation of Papua New Guinea began staying in a prison cell with her young baby even though she had committed no crime. A study in one region found 41 per cent of men had raped a woman who was not their partner. Remarkably, these figures are believed to be unreliable and the problem may be worse. Few women report assaults because they do not expect authorities to assist or fear retribution from their attacker, while hospitals and medical services — often underfunded in this poverty-stricken nation — frequently fail to record crimes. S ome of the most brutal cases have involved accusations of witchcraft and sorcery , in which women are brutally beaten, tortured and killed in attacks that can involve hundreds of men, women and children from entire villages.
Genetics may explain up to 25% of same-sex behavior, giant analysis reveals
Why 70 per cent of Papua New Guinea's women will be raped in their lifetime
A new study suggests many genes, each with small effects, may play a role in same-sex sexual behavior. People who have had same-sex partners are more likely to have one or more of certain DNA markers, according to the largest ever search for genes linked to sexual orientation. Even all the markers taken together, however, cannot predict whether a person is gay, bisexual, or straight. Instead, hundreds or thousands of genes, each with small effects, apparently influence sexual behavior. The paper, published today in Science , builds on results presented by the same team at a meeting. The published study emphasizes that the genetic markers cannot be used to predict sexual behavior.
Working in close consultation with advocacy and outreach groups, an international group of researchers has provided the clearest evidence into the genetic underpinnings of same-sex sexual behavior. The team identified five genomic variants that are associated with same-sex sexual behavior while also showing that there is no genomic signature that predicts how a person will behave sexually. The team analyzed data from the UK Biobank , individuals aged 40—70 and a cohort from 23andMe 68, —largely from the United States.
The aim of the present study was to examine the preferences of a relatively isolated, indigenous population i. A total of 53 women and 52 men participated in the study. Additionally, the observed preferences were modified by contact with different cultures, age, and accessibility of food resources pig possession. Our results suggest that human norms of attractiveness are malleable and can change with exposure to different environments and conditions.
