在最近的一篇Cell文章中，Solovei et al.（2009）已经表明，夜间和日间哺乳动物（包括灵长类动物）的视杆细胞核以不同的模式组织，并且与视杆细胞相关的模式可能促进光感受器的有效光子捕获。他们的研究强调了在弱光环境下视觉系统的特殊选择压力，并提供了夜间祖先的新标志。这个标记可用于推进我们对活动模式进化的理解，可能包括祖先灵长类动物的行为生态学。
In a recent Cell article, Solovei et al.(2009) have shown that the rod cell nuclei of nocturnal and diurnal mammals (including primates) are organized in distinct patterns, and that the nocturnal-associated pattern likely facilitates efficient photon capture by the photoreceptors. Their research underscores the exceptional selective pressures placed on the visual system in low light environments and provides a new marker of nocturnal ancestry. This marker can be used to advance our understanding of activity pattern evolution, potentially including the behavioral ecology of ancestral primates.
