我们建议，从进化发育生物学（或“evo-devo”）领域的见解提供了一个框架，综合理解的起源行为多样性及其潜在的机制。为了实现这一目标，在这篇评论中，我们从分子、细胞和网络水平的特性出发，以神经系统为重点，提出了行为进化中的关键问题。通过这种方式，我们强调了进化-发育分析的中心机械属性-如弱联系，多功能性，探索机制，关键性，简并性，冗余性和模块性-如何影响神经回路功能，因此可以通过选择过滤的行为变化范围。我们概述了为什么在整个个体发育的分子和神经系统的比较研究将提供新的见解神经回路和行为的多样性。
We propose that insights from the field of evolutionary developmental biology (or 'evo-devo') provide a framework for an integrated understanding of the origins of behavioural diversity and its underlying mechanisms. Towards that goal, in this Commentary, we frame key questions in behavioural evolution in terms of molecular, cellular and network-level properties with a focus on the nervous system. In this way, we highlight how mechanistic properties central to evo-devo analyses - such as weak linkage, versatility, exploratory mechanisms, criticality, degeneracy, redundancy and modularity - affect neural circuit function and hence the range of behavioural variation that can be filtered by selection. We outline why comparative studies of molecular and neural systems throughout ontogeny will provide novel insights into diversity in neural circuits and behaviour.
