Problem:
Fireflies are a group of bioluminescent beetles that create patterns of light to attract mates. They possess a complex light organ on their abdomen. This organ is composed of a spacious chamber where they mix a protein and a high-energy substrate that react together to release light. During the early evenings in summer, male fireflies flit about open fields and flash different patterns to females waiting in the grass. Females signal in a duet back to males with their own light. As juvenile larvae, before they are sexually mature, fireflies also have light organs that they use to deter would-be predators, especially at night. In both cases, brighter light organs are more effective: bright flashes attract more mates in adults and scare off attackers better in juveniles. In some species of fireflies that shifted to being most active during the day, the adult stage has lost bioluminescence (coinciding with the adult behavior) because it is not an effective signal in daylight, but juvenile stages - which are mainly active at night - still possess functioning light organs. Based on information in the above example, although the evolution of all traits are a mix of structure, function and history - which. Need Assignment Help?
