Summary
Understanding the relationship between the social environment and cognition. The predominant theory for the evolution of intelligence, the social intelligence hypothesis (SIH), posits that within-group social interactions drive cognitive evolution. But the SIH overlooks a major component of social life: interactions with outsiders of the same species. Using a unique combination of meta-analytical and experimental approaches, the DECRA project will test the predictions of an expanded SIH, incorpo ....Understanding the relationship between the social environment and cognition. The predominant theory for the evolution of intelligence, the social intelligence hypothesis (SIH), posits that within-group social interactions drive cognitive evolution. But the SIH overlooks a major component of social life: interactions with outsiders of the same species. Using a unique combination of meta-analytical and experimental approaches, the DECRA project will test the predictions of an expanded SIH, incorporating the “Napoleonic” cognitive challenges posed by outsiders. The expected outcome is to gain a new understanding of which factors govern cognitive evolution – one of the longest-running debates in evolutionary biology.Read moreRead less
Transgenerational Consequences of Different Environmental Experiences. The project aims to deliver an integrative overview of behavioural, evolutionary and environmental epigenetics. In particular, by studying why stress-related experiences of organisms (e.g. exposure to toxins) can be passed onto the future generations regardless of its seemingly fitness-reducing impacts. It also aims to test if the seemingly beneficial effect of non-stress related experiences (e.g. environmental enrichment) ca ....Transgenerational Consequences of Different Environmental Experiences. The project aims to deliver an integrative overview of behavioural, evolutionary and environmental epigenetics. In particular, by studying why stress-related experiences of organisms (e.g. exposure to toxins) can be passed onto the future generations regardless of its seemingly fitness-reducing impacts. It also aims to test if the seemingly beneficial effect of non-stress related experiences (e.g. environmental enrichment) can be inherited transgenerationally. This project involves both research synthesis (e.g. meta-analysis) and experiments on zebrafish employing cutting-edge statistical, computational and molecular methods along with behavioural assays. Also, the outcomes of the synthesis are expected to guide future work in the field. Read moreRead less
Sex chromosomes and speciation: chromosome inversion and the large Z-effect. This project aims to understand the divergence of species and the importance of two genomic features of often disproportionately large effect between young taxa – the sex chromosomes, and chromosome inversions. The research will integrate genomics and transcriptomics with the study of traits closely aligned to speciation in birds – song, colour, and sperm morphology and protein composition. The project will provide sign ....Sex chromosomes and speciation: chromosome inversion and the large Z-effect. This project aims to understand the divergence of species and the importance of two genomic features of often disproportionately large effect between young taxa – the sex chromosomes, and chromosome inversions. The research will integrate genomics and transcriptomics with the study of traits closely aligned to speciation in birds – song, colour, and sperm morphology and protein composition. The project will provide significant benefits such as enhancing Australia’s strength in the field of evolutionary biology.Read moreRead less
Pair bonding: is it all in the brain? This project aims to understand the interaction between classic pair bonding neural circuits, parasites, and the immune system in sleepy lizards. Social bonds are a cornerstone of human societies, especially true of the pair bond and this project expects to generate knowledge to help understand why healthy adult pair bonds are the single best predictor of longevity in humans. The expected outcomes of this project are to reveal the mechanistic basis of pair b ....Pair bonding: is it all in the brain? This project aims to understand the interaction between classic pair bonding neural circuits, parasites, and the immune system in sleepy lizards. Social bonds are a cornerstone of human societies, especially true of the pair bond and this project expects to generate knowledge to help understand why healthy adult pair bonds are the single best predictor of longevity in humans. The expected outcomes of this project are to reveal the mechanistic basis of pair bonding by identifying the brain regions, cell types and neurochemicals that promote pair bonding behaviour — for the first time in a wild animal. This project should provide significant benefits by increasing our knowledge of how pair bonds promote wellness.Read moreRead less
