This research will enhance our understanding of the ancient origins of Australia's unique floral heritage. By developing new molecular modelling methods, it will strengthen Australia's position at the cutting edge of evolutionary phylogenetics. When Australia separated from Gondwana by continental drift 32 million years ago, the changed ocean circulation patterns triggered global climate change. The result was turnover of biota world-wide and dramatic changes within Australia. We will develop new insights into the rate and mode of these changes that will have international significance. Understanding the long-term turnover of flora from previous global climate changes will help to predict the impact of current and future climate change.

这项研究将加深我们对澳大利亚独特花卉遗产的古老起源的了解。通过开发新的分子建模方法，它将加强澳大利亚在进化系统发生学前沿的地位。3200万年前，当澳大利亚因大陆漂移而与冈瓦那分开时，海洋环流模式的变化引发了全球气候变化。其结果是生物群在世界范围内的周转和澳大利亚国内的戏剧性变化。我们将对这些变化的速度和模式产生新的见解，这些变化将具有国际意义。了解植物区系在过去全球气候变化中的长期周转将有助于预测当前和未来气候变化的影响。
