昆虫的视觉器官以其令人印象深刻的进化保守性而闻名。现在人们普遍认为，由具有四个视锥细胞的小眼构成的复眼可以追溯到昆虫和甲壳类动物的最后一个共同祖先。在像果蝇和蝌蚪虾这样不同的物种中，早期复眼的逐步细胞模式步骤表现出详细的相似性，这意味着 5 亿年的发育保存。引人注目的是，昆虫视觉器官也存在着神秘的多样性，这证明了进化的多功能性，即使是最顽强的结构也能塑造成新的东西。我们通过各种不同昆虫眼睛的结构和功能来探索这一令人着迷的方面。这包括对扭曲翅昆虫独特的复合单室组合眼和内翅目昆虫专门幼虫眼睛的奇异进化轨迹的研究。
The visual organs of insects are known for their impressive evolutionary conservation. Compound eyes built from ommatidia with four cone cells are now accepted to date back to the last common ancestor of insects and crustaceans. In species as different as fruit flies and tadpole shrimps, the stepwise cellular patterning steps of the early compound eye exhibit detailed similarities implying 500 million years of developmental conservation. Strikingly, there is also a cryptic diversity of insect visual organs, which gives proof to evolution's versatility in molding even the most tenacious structures into something new. We explore this fascinating aspect in regard to the structure and function of a variety of different insect eyes. This includes work on the unique compound-single-chamber combination eye of twisted-winged insects and the bizarre evolutionary trajectories of specialized larval eyes in endopterygote insects.
