This project aims to discover primary new data to pinpoint the timing, anatomical origins and phylogenetic significance when two key sensory systems first appeared in modern vertebrates: electroreception and specialised nocturnal vision. Such abilities today allow high diversity of vertebrates to co-exist within the same geographical range, for example on tropical reefs or rainforest communities, through careful temporal niche partitioning where reliance on other sensory systems takes over from vision and olfaction as the principal method of prey detection. This project aims to elucidate how the modern fish diversity was shaped by such significant early evolutionary events.

该项目旨在发现主要的新数据，以确定两个关键感觉系统首次出现在现代脊椎动物中的时间，解剖学起源和系统发育意义：电感受和专门的夜间视觉。今天，这种能力使高度多样性的脊椎动物能够在同一地理范围内共存，例如在热带珊瑚礁或雨林社区，通过仔细的时间生态位划分，依靠其他感觉系统取代视觉和嗅觉作为猎物检测的主要方法。该项目旨在阐明现代鱼类多样性是如何由这些重要的早期进化事件塑造的。
