Indeed as a factual matter their…, 30,000 Facets Give Dragonflies a Different Perspective: The Big Compound Eye in the Sky, What has always attracted me to developmental biology is the ability to see the unfolding of pattern—simplicity becomes complexity in a process made up of small steps, comprehensible physical and chemical interactions that build a series of states leading to a mostly robust conclusion. OT but not to be neglected under the present circumstances: Grrl - please ask your current companions about the purity of Finns and Swedes. ;-) ), As an amateur photographer I discovered that there are different colored eyes amongst dragonflies, at least there are where I live.
