An animal that lived 429 million years ago had compound eyes almost identical to those of modern insects like bees and dragonflies. The finding implies that the compound eye evolved very early in the ...

Five hundred million years ago, the oceans teemed with trillions of trilobites - a now extinct group of marine arthropods ruling the seas for more than 270 million years. Over 20,000 species have been ...

Among fossils, trilobites are rock stars. They are adorable (as stony arthropods go), with a segmented shape distinctive enough to be a common logo. But they’re also fascinating because there are so ...

Copying the human lens takes robotic technology a long-way; however, the compound eyes of insects provides a different level of visualization when it comes to peripheral vision. Other advantages that ...
