项目摘要

THE LONG-TERM GOAL OF MY RESEARCH PROGRAM IS TO UNDERSTAND HOW NOVEL FEATURES ORIGINATE AND DIVERSIFY IN COMPLEX BIOLOGICAL SYSTEMS. This a central problem in evolutionary biology that has remained largely unresolved for over 100 years. My research program is on the leading edge of the emerging field of Eco-Evo-Devo, which integrates the traditionally separate fields of ecology, evolution, and developmental biology. A main focus of this field is to understand how genes and environment interact during development to generate novel features and how these features subsequently diversify in their ecological environments. We focus on a key morphological trait in ants – the worker caste – whose origin and diversification has enhanced their division of labor, and consequently, their ecological and evolutionary success. I will capitalize on several recent discoveries that have started to uncover how novel worker castes originated during 3 major morphological transitions in ant evolution. These transitions mark the progressive increase in complexity of ant societies beginning with (1) the origin of eusociality (true social behavior); followed by (2) the ‘point of no return’ (when eusociality becomes irreversible because the reproductive capacity of workers is significantly reduced); and culminating in (3) the diversification of a single worker caste into a complex system of morphological and behavioral subcastes. Over the next five years, we will initiate 3 projects that aim to understand the developmental mechanisms underlying 3 major transitions in ant evolution. These 3 projects will use the integrative approaches of Eco-Evo-Devo (molecular and developmental biology, endocrinology, genomics, fieldwork, population and comparative biology and behavior):
我的研究计划的长期目标是了解复杂生物系统中新的特征是如何起源和多样化的。这是进化生物学中的一个中心问题,100多年来基本上一直没有解决。我的研究项目处于生态进化开发这一新兴领域的前沿,该领域整合了生态学、进化论和发育生物学这三个传统上相互独立的领域。该领域的一个主要焦点是了解基因和环境在发育过程中如何相互作用以产生新的特征,以及这些特征随后如何在其生态环境中多样化。我们专注于蚂蚁的一个关键形态特征-工人阶级-其起源和多样性加强了它们的劳动分工,从而促进了它们在生态和进化上的成功。我将利用最近的几个发现,这些发现已经开始揭示在蚂蚁进化的三个主要形态转变中,新的工人种姓是如何起源的。这些转变标志着蚂蚁社会复杂性的逐步增加,从(1)共生社会(真正的社会行为)的起源开始;(2)“不归路点”(由于工蚁的生殖能力显著下降,共生社会变得不可逆转);以及(3)单一工种种姓的多样化,形成一个复杂的形态和行为亚种姓系统。在接下来的五年里,我们将启动三个项目,旨在了解蚂蚁进化中三个主要转变背后的发展机制。这3个项目将使用Eco-Evo-Devo(分子和发育生物学、内分泌学、基因组学、田野调查、种群和比较生物学及行为)的综合方法:
