This project aims to improve our understanding of the cause of evolutionary limits. It will test the prediction that trait combinations with high genetic variation are highly correlated with other traits, and therefore are more evolutionary limited than they appear. This project will develop and implement novel evolutionary and statistical manipulations and methods to test this prediction, and is expected to provide new methods for the study of selection. A better understanding of evolutionary limits will provide a significant benefit, enabling better predictions of how natural populations will evolve over short and long time-scales, and their risks of extinction.

这个项目旨在提高我们对进化极限原因的理解。它将检验这样一种预测，即具有高遗传变异的特征组合与其他特征高度相关，因此比它们看起来更受进化限制。该项目将开发和实施新的进化和统计处理方法来检验这一预测，并有望为选择的研究提供新的方法。更好地理解进化极限将带来重大好处，使人们能够更好地预测自然种群在短时间和长时间尺度上将如何进化，以及它们灭绝的风险。
