The New York Times has an interesting story about the first flyers... insects. The article discusses recent research to discover how insects evolved the ability to fly. Strange to think that all those Mazon Creek flying insects were pretty new to the world of flying!
Beetle wings are often hidden. Nestled behind armored shields on the beetle’s back, they unfurl in whirring sheets, whisking their clumsy owners from danger. Beetles don’t have more than two sets of wings — unless they’re in Yoshinori Tomoyasu’s lab.
In research recently published in the Proceedings of the National Academy of Sciences, Dr. Tomoyasu and co-author David Linz genetically engineered beetle larvae with wings on their abdomens, part of an ongoing attempt to unpack one of evolution’s greatest mysteries: how insects gained the ability to fly.
Insects took to the empty skies sometime between 300 and 360 million years ago, long before birds, bats or pterosaurs. Wings allowed them to conquer new habitats and ecological niches, and Insecta quickly established themselves as one of the most diverse and successful animal classes, a position they still hold today.
