Research Paper: "Common Design Principles" Explain Patterns of Retinal Cells in Insects

A new article in the journal Trends in Genetics bears an intriguing title: "The evolutionary diversity of insect retinal mosaics: common design principles and emerging molecular logic." The mention of "common design principles" doesn't mean that the authors advocate intelligent design, but their research unwittingly bears on the subject.

They write about patterns, or mosaics, of light-receptor cells in insect eye retinas that are found repeatedly in widely diverse types of insects. These fe...
