Some individual fish like to be close together in 'schools', while other individuals like to be alone. A pair of recent papers dissects the genetic basis of schooling behavior, showing that genetic changes in sensory systems are involved when this social behavior is lost during evolution.
有些鱼喜欢成群结队地“洄游”，而有些鱼则喜欢独来独往。最近的两篇论文剖析了群居行为的遗传基础，研究表明，当这种社会行为在进化过程中消失时，感觉系统的遗传变化就会涉及其中。
