Human sexuality and gender expression is a continuum, much in the same way that height and weight are. Not everyone fits into the categories of strictly straight, strictly gay, male or female. Dichotomising sexuality and gender ignores the continuum or clusters of individuals who don’t fall into one of two (and only two) categories and we can fall prey to thinking that one is “normal”. While people may find comfort in the “born this way” argument, looking for a “gay gene” can indicate a level of non-acceptance. If the variation between individuals is collapsed to a binary then the focus becomes on asking why one end of the spectrum exists, when the better question would be to ask how variation in sexuality evolved and came about.
The inaugural Science Gossip event was held at the Royal Society of Victoria on the 15th of May. The event planted artists, philosophers, the public and scientists in common ground to discuss and unravel the secrets of forest communication, complexities and communities. Dr Renee Beale invited RSV members and guests to ‘really see trees.’
It has long been a popular perception that risk-taking and status-seeking have evolved as masculine traits, as there is less selective pressure for women to develop a “competitive edge” and to take risks. Professor Cordelia Fine discussed the roles of men and women in society, particularly how their behaviour contributes towards “reproductive return” – their passing on genes to offspring and continuing their ancestral line. Scholars have previously reported on links between testosterone levels and risk-taking, their argument being that where men evolved a promiscuous streak to be competitive in order to acquire or defend their status and sexual opportunities, the female strategy has been more focused on ensuring they have enough resources to care for their offspring. As Professor Fine points out, however, women can be big risk-takers in their own right.
