A recently published study offers one of the most comprehensive reviews to date of the scientific literature on the subculture of involuntary celibates; a group of men who see sex as a denied right and transform frustration into an ideology steeped in misogynistic discourse

Diets of wild orangutans are “culturally-dependent”: adult Sumatran orangutans have knowledge of around 250 edible food items, which is more than any one individual can attain without learning from other individuals.

Developmental experiments “in silico”: using computer simulations based on 12 years of observations on wild orangutans, researchers show that orangutans fail to develop “adult-like” diets if deprived of key social interactions that facilitate learning.

Deep roots of cultural inheritance: adult orangutan’s diets are the product of information that many different individuals must have discovered and learnt from each other. Humans’ capacity to accumulate broad cultural repertoires – to breadths no individual could produce alone – is potentially a capacity that evolved at least 13 million years, in our common ancestor with great apes.
