"Insects exhibit extensive variation in the shape and size of their eyes, which contributes to adaptive differences in their vision. Our study comparing Drosophila species that differ in eye size reveals one of the genetic mechanisms that can make the facets of their eyes bigger and potentially allow greater contrast sensitivity." > Insects exhibit extensive variation in the shape and size of their eyes Trivial, and obvious. > contributes to adaptive differences in their vision Who knows? Not covered. They measured big eyes. > reveals one of the genetic mechanisms that can make the facets of their eyes bigger One of them! Brilliant! "all of the genetic mechanisms", now that would be a claim. > potentially allow greater contrast sensitivity "potentially" covers a lot of ground. Who knows? Not covered.
