One of the challenges in evaluating arguments for extending the conceptual framework of evolutionary biology involves the identification of a tractable model system that allows for an assessment of the core assumptions of the extended evolutionary synthesis (EES). The domestication of plants and animals by humans provides one such case study opportunity. Here, I consider domestication as a model system for exploring major tenets of the EES. First I discuss the novel insights that niche construction theory (NCT, one of the pillars of the EES) provides into the domestication processes, particularly as they relate to five key areas: coevolution, evolvability, ecological inheritance, cooperation and the pace of evolutionary change. This discussion is next used to frame testable predictions about initial domestication of plants and animals that contrast with those grounded in standard evolutionary theory, demonstrating how these predictions might be tested in multiple regions where initial domestication took place. I then turn to a broader consideration of how domestication provides a model case study consideration of the different ways in which the core assumptions of the EES strengthen and expand our understanding of evolution, including reciprocal causation, developmental processes as drivers of evolutionary change, inclusive inheritance, and the tempo and rate of evolutionary change.
评估扩展进化生物学概念框架的论据所面临的挑战之一，涉及识别一个易于处理的模型系统，该系统能够对扩展进化综合理论（EES）的核心假设进行评估。人类对植物和动物的驯化提供了这样一个案例研究机会。在此，我将驯化视为探索EES主要原则的一个模型系统。首先，我将讨论生态位构建理论（NCT，EES的支柱之一）对驯化过程所提供的新见解，特别是与五个关键领域相关的见解：共同进化、进化能力、生态遗传、合作以及进化变化的速度。接下来，本讨论将用于构建关于动植物初始驯化的可检验预测，这些预测与基于标准进化理论的预测形成对比，展示了如何在多个初始驯化发生的地区对这些预测进行检验。然后，我将更广泛地思考驯化如何提供一个模型案例研究，以考虑EES的核心假设以不同方式加强和扩展我们对进化理解的情况，包括相互因果关系、作为进化变化驱动力的发育过程、包容性遗传以及进化变化的节奏和速率。
