Most ant species are born into royalty. But for Indian jumping ants, female workers can fight for the crown. Once they have their order, almost any ant that might need some attention just has to bend the rules.
This inheritance of princess-like status is so ingrained, the worker ants can just shrink their heads and grow them back when needed. To create a bigger space, a queen ant shrinks her brain and stores it in a gland near her front legs, hidden from predators.
Understanding how the queen can morph into this space and keep her brain protected is key to better understanding how workers spew out so much waste oil when they jump course and attack their hungry competitors.
To see how this transformation occurs, Timothy Mao, a biologist at the University of Ontario Institute of Technology in Toronto, used a toolkit of gene therapy techniques to turn off the queen ant's reproductive genes. He took some techniques from related species: for example, monkeys, grapes and horses all have one tiny gland for storing sperm and are therefore defined as asexual.

While these other animals do not produce sperm when they stop reproducing — they still get two eggs each year — the queens of the jumping ant are still capable of secretly storing sperm inside her body and carrying it into her flowering appearance.
Soon after Mao's experiment, British entomologist Brett Webb noted a small cluster of matching ants in California. When in their female state, these ants leave no trace of their former life as males inside their chrysalis. How did they do it?
Here, the researchers shed some light on sex selection. In ant societies, ant workers drone in front of the queen. During the queen's fertile months, workers' genetic material is concentrated at the chrysalis, serving as bait that lets the queen who has recently mated evolutionarily forward her worker lineage. But when she needs fresh DNA in the three months after it lost its sperm, the worker ants have to remove the material from their queens through a type of war between the queen and her supposedly dead colony guard.
Jumpers take over
The original pollinator ants arrived in the 10th century Florence, then occupied the elsewhere School of Florence for 30 years. Next came several waves of invaders looking for an earnest place to build comfortable nests, so to speak.
