This project aims to characterise the variation in molecular evolutionary rates across the Tree of Life. Despite advances in genetic methods and genomic data, a critical gap remains in knowledge of evolutionary rates across species. The project will evaluate and refine methods for estimating rates, develop genomic data for molecular clocks, create an online database of rate estimates, and reconstruct ecological communities’ responses to past environmental and climatic factors. The project’s database of evolutionary rates in different species is expected to increase understanding of evolutionary and demographic events across species, including the Australian biota, and improve conservation efforts.

该项目旨在描述生命之树中分子进化速率的变化。尽管在遗传学方法和基因组数据方面取得了进展，但在跨物种进化速率的知识方面仍然存在着重大差距。该项目将评估和改进估计速率的方法，为分子钟开发基因组数据，创建速率估计的在线数据库，并重建生态群落对过去环境和气候因素的反应。该项目的不同物种进化率数据库预计将增加对包括澳大利亚生物群在内的物种进化和人口统计事件的了解，并改善保护工作。
