Eyespots, the circular markings of contrasting colors found on the wings of many butterfly species, are used by these fluttering creatures to intimidate or distract predators. A team of scientists led by Professor Antónia Monteiro from the National University of Singapore (NUS) conducted a research study to better understand the evolutionary origins of these eyespots, and they discovered that eyespots appear to have derived from the recruitment of a complex network of genes that was already operating in the body of the butterflies to build antennae, legs, and even wings.
