The nervous system is evolutionarily conservative compared to the peripheral appendages that it controls. However, species-specific behaviors may have arisen from very small changes in neuronal circuits. In particular, changes in neuromodulatory systems may allow multifunctional circuits to produce different sets of behaviors in closely related species. Recently, it was demonstrated that even species differences in complex social behavior may be attributed to a change in the promoter region of a single gene regulating a neuromodulatory action.
与它所控制的外周附属器官相比，神经系统在进化上是保守的。然而，物种特异性行为可能源于神经回路中非常微小的变化。特别是，神经调节系统的变化可能使多功能回路在密切相关的物种中产生不同的行为模式。最近有研究表明，即使是复杂社会行为中的物种差异，也可能归因于单个调节神经调节作用的基因启动子区域的变化。
