The ant queen - thanks
By Hannah Seo April 14, Royal status is a coveted thing. So coveted, that Indian jumping ants will shrink their brains and expand their ovaries just for a shot at the crown. Ant colonies are a family affair: Most of them have one queen, who is the only reproductive member of the clan, and the worker ants are her children. But new research shows that, with the Indian jumping species, vast numbers of worker ants will go through intense physiological changes to redevelop the ability to reproduce and throw in their hat for the crown. Contenders shrink their own brains by as much as 25 percent, minimize their venom sacs, and expand their ovaries while increasing their oocytes or eggs seven-fold. The findings were published in the journal Proceedings of the Royal Society B. In order to study their behavior and physiology, scientists identified two gamergates in each of 30 Indian jumping ant colonies reared in the lab. They left one gamergate ant as it was, and reverted the other back to worker status through solitary isolation. Researchers then added the reverted gamergates back to their colonies, observing and comparing behavioral and physiological changes between the pairs. the ant queenOpinion you: The ant queen

Most ant species are born into royalty. But for Indian jumping ants, female workers can fight for the crown. In a study published Wednesday in the journal Proceedings of the Royal Society B, scientists discovered that Indian jumping ants can shrink and regrow their brains within a few weeks the ant queen a feat that has never been seen before in insects and is also incredibly rare in the animal kingdom. The Indian jumping ants, also known as Harpegnathos saltatorare inchlong arthropods known for their forceps-like jaws and large black eyes. And as their name suggests, these ants can be found in the ant queen forests of India where they hunt and leap several inches in search of prey.

Qqueen lifespan of most ant colonies is often dependent on the lifespan of the queen. When an Indian jumping ant queen dies, more than half of the colony's female workers participate in a monthlong "tournament" to vie for a seat at the top, Penick said. Indian jumping ant colonies can have numerous queens. As hundreds the ant queen female workers duel each other, they begin to undergo a physiological change that transforms them into queenlike workers called gamergates — "not the online harassment campaign," he said, referring to a harassment campaign that targeted several women in the video game industry in A small group of eight to 10 workers will constructivist epistemology victorious while the losers the ant queen return to their worker duties, Penick said.
The victors will then activate their ovaries to take on the previous role of the queen, "essentially an egg-laying factory," according to Penick.
During this period, the ovaries of gamergates will increase five times in size while their brains will shrink up to 25 the ant queen compared to the anatomy of the workers. Penick said the Indian jumping ant colonies used in the study were the same ones that were collected in India almost 20 years ago and were the first epigenome for the species sequenced. At some point, he said, he and the other researchers became interested in determining whether brain shrinkage was reversible and created queem experiment to isolate newly formed gamergates from the colony.

He said he expected them to die, but what they discovered was that the Indian jumping ants can regenerate the size of the brains and shrink their ovaries back to the size of workers. It's gone forever. The ants wueen the ant queen a "model of developmental plasticity" that can provide details about "what genes control this phenomenon and what parts of the brain retain the ability to regrow," he said. Penick added he believes queens can revert back to their original form because the losers of the duel for the crown needed to be able to return to their responsibilities as a worker.

Bravo, seems remarkable idea to me is
I consider, that you are not right. I can defend the position. Write to me in PM, we will discuss.
