How we inherit masculine and feminine behaviours: a new idea about environment and genes

The Conversation, August 18, 2017 3.22pm AEST

What if thousands of years of gendered environments actually reduced the need to develop genetic mechanisms to ensure gender differences? This is the idea we suggest in our new paper.

Advances in evolutionary biology recognise that offspring don’t just inherit genes. They also reliably inherit all kinds of resources: a particular ecology, a nest, parents and peers. And it appears that these stable environmental factors can help ensure the reliable reproduction of a trait across generations.

Mystery of the female orgasm may be solved

The purpose of the euphoric sensation of the female orgasm has long perplexed scientists, as it is not necessary for conception, and is often not experienced by women during sex itself. Now researchers in the US say they might have found its evolutionary roots. Human female orgasm, they say, might be a spin-off from our evolutionary past, when the hormonal surges that accompany it were crucial for reproduction.
