About The Author

Sabine Nöbel is a research fellow at the Institute for Advanced Study., Toulouse. Her background is in the behavioural ecology of Poeciliids and Drosophila studying the non-genetic inheritance of mating preferences using mate-copying, by which females build mating preferences by observing and copying conspecific females’ mate-choice. She studies how new, socially learnt mating preferences can invade a population and persist across generations.

                       

New Toulouse-Led Scientific Study Reveals Drosophila melanogaster Can Transmit Sexual Preferences Culturally Over The Long Term

A Toulouse-led interdisciplinary research consortium shows that the fruit fly has all the cognitive capacities to culturally transmit their sexual preferences across generations, potentially leading to the emergence of long-lasting traditions in sexual preferences. On top of providing the first experimental toolbox to study animal cultures in any species, this study suggests that the cultural process likely participated to the evolution of a vastly broader spectrum of species and over periods much longer than ever envisioned. An abundant theoretical literature...

Male Mate-Copying Practices In Drosophila melanogaster Males 

Finding the right partner can be difficult, time-consuming, and prone to errors. And that is true for species across the tree of life, not just humans. To avoid these costs, animals from a wide range of taxa have been shown to use public information, i.e. information that is accessible to all individuals. In particular, individuals can assess the quality of potential mates by observing others and learning from their mating performance to develop their own sexual preference. This form of...
