9405537 Vermeij PI will examine evolution and function of labral spines in gastropods, Oligocene to Recent, including experiments on modern gastropods and systematics of the studied groups. Many attributes of organisms are interpretable as adaptations that enhance an individual's competitive ability or defensive performance; under what conditions do such adaptations evolve and spread? This study will test the hypothesis that enemy-related adaptations of marine species mainly arose in lineages found in warm, productive waters. The work will contribute to an understanding of biological escalation and serve as an example of the integrated approach to answering fundamental questions in evolutionary biology, and of the macroeconomic perspective on the history of life.

9405537 Vermeij PI 将研究渐新世到近代腹足动物盂唇刺的进化和功能，包括现代腹足动物实验和研究群体的系统学。 生物体的许多属性都可以解释为增强个体竞争能力或防御能力的适应；这种适应是在什么条件下进化和传播的？ 这项研究将检验这样一个假设：海洋物种与天敌相关的适应主要出现在温暖、多产的水域中发现的谱系中。 这项工作将有助于理解生物升级，并作为回答进化生物学基本问题的综合方法的例子，以及生命史的宏观经济视角的例子。
