Michael Jennions, an evolutionary biologist at the Australian National University and STIAS Fellow will present a public lecture with the title:
The Ins and Outs of Sex: a few fun questions
Many of us are fascinated by sex and differences between the sexes. In this talk I will introduce some of the tools and logic that evolutionary biologists use to predict how animals will invest in different traits – be these physiological, morphological or behavioural. I will illustrate this approach using three (hopefully) engaging examples from my own lab’s research that are associated with male-female interactions. First, what is the optimal ratio of sons to daughters to produce? If you believe the answer is to make as many sons as daughters then you are in for a surprise. Second, is there any evidence that smarter males are sexier? Some of you will be hoping the answer is a resounding yes. Third, is there more variation among males than there is variation among females in behaviour? The answer has potential implications for popular arguments you will see in the media to explain why more men than women are described as geniuses.
Michael Jennions is an evolutionary biologist working at the Australian National University. He completed his BSc and MSc at Wits University, followed by a PhD at Oxford University. He then spent five years at the Smithsonian Tropical Research Institute in Panama. He has worked on frogs, zebra finches, damselflies, fiddler crabs, plants, cichlid fish, crickets, beetles and live-bearing fish. Aside from evolutionary biology, with a special focus on sexual selection, he is interested in the dangers posed by a scientific system with reward incentives that encourage biased presentation of research findings and even fraud. His only claim to fame is a Youtube video with 2.2 millions views. It is on his most frivolous research. The title is ‘Does size matter?’, and you can work where it goes from there. He’s also pretty stoked that, for unknown reasons, local crime novelist Deon Meyer follows him on Twitter.
