摘要

几个世纪以来，物种的多样化一直吸引着研究人员，但我们对行为如何影响生态位适应以及行为进化的遗传机制却知之甚少。在最近的研究中，Sommer-Trembo 等人（《科学》，384, 470-475, 2024 年）证明了调控基因 cacng5b 在调节非洲坦噶尼喀湖慈鲷这种最特殊的适应性辐射鱼类的探索行为表型变异中的关键作用。

Just keep exploring: Genetics of fish niche adaptation.

Although the diversification of species has fascinated researchers for centuries, we know remarkably little about how behavior influences niche adaptation and the genetic mechanisms through which behavior evolves. In their recent study, Sommer-Trembo et al. (Science, 384, 470-475, 2024) demonstrate a critical role for the regulatory gene cacng5b in modulating phenotypic variation in exploratory behavior in one of the most exceptional adaptive radiations: the African cichlid fishes of Lake Tanganyika.
