Evolution has generated an enormous variety of morphological, physiological, and behavioral traits in animals. Decades of research have shown that variation in the regulatory regions of particular genes is associated with species differences in morphology (e.g., wing pattern). But how do behaviors evolve in different directions in species equipped with similar neurons and molecular components? Solving these mysteries requires an understanding of the relationship between evolutionarily adaptive changes in behavior and structural/functional changes in neural circuits.

进化在动物身上产生了各种各样的形态、生理和行为特征。几十年的研究表明，特定基因调控区域的变异与物种形态差异（如翅膀图案）有关。但是，在拥有相似神经元和分子成分的物种中，行为是如何向不同方向进化的呢？解决这些谜团需要理解行为的进化适应性变化与神经回路的结构/功能变化之间的关系。
