Solo Exhibition: Agonism / Antagonism
20th September to 21st December, 2018 - Private View 19th September
Grant Museum of Zoology
We are proud to present Agonism / Antagonism; an exhibition resulting from Neus’s residency in the laboratory of Dr Max Reuter, in the Research Department of Genetics, Evolution, and Environment at UCL.
This exhibition explores the forces that drive and constrain genetic evolution. This focus, and many of the artworks shown, are the result of Neus’ residency embedded in Max’s research group and conversations between Neus, Ben and Max. The artworks address the genetic concepts that are studied in Max’s laboratory, as well as the means and approaches that are used. Central to this is the lab's work with the model organism Drosophila melanogaster, also known as the fruit fly. Neus has found inspiration in the aesthetics of the laboratory environment and connections between the media in which she has previously worked and the materials that constitute the fruit flies themselves.
What is genetic antagonism?
Darwin's 'survival of the fittest' captures natural selection in a form that is familiar to many. However, adaptive evolution is often not as simple as this catch-phrase implies. One aspect that is explored in this exhibition is adaptive constraint, where improvement in one aspect of an organism comes with negative effects in another aspect. This is a common problem for the evolution of male and female traits. Males and females perform different reproductive functions and are selected to show differences ranging from subtle variations in the morphology of internal organs to clearly contrasting body sizes, colouration or armaments. But developing these is far from easy, because both genders share a common genome and exchange genetic material every generation. This leads to a genetic coupling of their characteristics, where a mutation will tend to alter the genetic traits of both genders in a similar way. The combination between linked traits but opposing selection leads to a situation where genetic changes that alter a trait are beneficial to one sex but detrimental to the other—a phenomenon called genetic antagonism. Genetic antagonism can cause an evolutionary stalemate, where the sexes are stuck in an ongoing adaptive tug-of-war, with neither reaching their optimal trait value. To break the deadlock, genetic changes are required that allow males and females to use their genomes in a sex-specific way and express different phenotypes. Such resolution of sexual antagonism is thought to have occurred many times over evolutionary history, resulting in sometimes astonishing differences between the sexes. However, evidence is accumulating that suggests that this harmony is only superficial, with struggles continuing even in species with well-developed dimorphism between the sexes.
Why Agonism / Antagonism?
Agonism, is an ancient Greek political theory that emphasises the importance and necessity of conflict within politics. We thought that is a good metaphor for genetic antagonism; its inevitability within sexually reproducing species implies that it is ultimately necessary for the fitness of a species in the wider world. Ultimately, genetic agonism might have been a better term for the phenomenon!
