Now, scientists at the Rockefeller University have actually found a way that metabolic interdependence among members of an ant nest might have evolved.; Ant pupae– which are comparable to the chrysalis stage of the butterfly– produce a milklike compound derived from molting fluid that is consumed by both adult ants and larvae.” It is an actually neat research study, due to the fact that it is determining a brand-new type of social transfer that no one had actually even actually seen before,” states Adria LeBoeuf, who studies mouth-to-mouth fluid exchange behavior (trophallaxis) in ants at the University of Fribourg in Switzerland, and who didnt work on the brand-new study.A honeypot ant (Myrmecocystus mexicanus) drinks fluid from a cocoon.DANIEL KRONAUERIn ant nests, the queens recreate however the employees do not, and for years it had actually been a mystery why some people would pass up the opportunity to reproduce to support a queen instead. Its truly this milk-like fluid for the larvae,” he says.The scientists carried out a proteomic analysis of the fluid, which not only verified that it was molting fluid packed with enzymes that help break down the ants discarded cuticle, but that it also consisted of hormones and neuroactive substances which Kronauer suspects might affect caste advancement of the larvae and the behavior of adults.To explore how general the finding was, Kronauers team sampled 5 various ant types in Central Park in New York City and discovered that pupae of all 5 types secrete this molting fluid. “So it appears this particular and ancient evolutionary innovation really develops these dependences in an ant colony, and it actually incorporates the ant colony as a superorganism,” he says.According to LeBoeuf, ants sharing their “leftover” molting fluid might have been the start of more fancy social transfers, such as forms of trophallaxis in which food is passed around amongst long chains of people.
