Scientists have opened the termites which have completely refused sex - RIA Novosti, 9/25/2018


MOSCOW, 25 Sep – RIA Novosti. Biologists have found in Japan extremely unusual colonies of termites which are completely consisting of the females capable to bring forth offspring without participation of males. Their photos and the description have been presented in the BMC Biology.© magazine of the Photo: Suzuki et al. / Nature Communications 2016 Biologists have taken the first step to "immaculate conception" of the person "Earlier we knew only about existence of some species of the bees and ants who are completely consisting of females. The sexual equality always reigns in colonies termites as was considered earlier, – they support equal number of the males and females breeding sexually. We have for the first time shown that it isn't obligatory so" — I have said Toshihisa Yashiro from Kyoto University (Japan). Some living beings, for example, lizards, hens or many insects, are capable to a parthenogenesis – self-fertilization at which two ova merge with each other, forming a germ, or the cage spontaneously begins development, despite a "vague" set of chromosomes. Such way of reproduction isn't characteristic of mammals at all, and there is no species of animals which would be capable to it even in the theory. The fact of existence of the similar beings breeding by "immaculate conception" is a big riddle for evolutionists. Refusing sex and exchange of genes with relatives, such animals become vulnerable for parasites who, according to a hypothesis of the Red queen, in that case develop quicker, than their victim.© Foto: Florida Fish and Wildlife Conservation Commission (FWC) Scientists have opened a phenomenon of "immaculate conception" among endangered fishes-pilpoetomu as considered scientific, such "sexless" animal species have to exist only short time, however practice shows that many of them exist already tens of millions of years. Yashiro and his colleagues have opened unusual subspecies of termites - the "amazons" who are living in Japan, pointing that similar "anti-evolutionary" practicians among social insects can exist throughout tens or even hundreds of millions of years. A few years ago the Japanese researchers studied the termites living on coast the islands of Honshu, Okinawa and other small archipelagoes surrounding the main territory of Japan. Their attention was drawn by the colonies of termites of a type of Glyptotermes nakajimai inhabiting practically all coastal woods of these islands. © RIA Novosti / Alexander Polyakov to Pass into an image bank Biologists for the first time have grown up full-fledged ova in лабораторииКак scientists, the populations of these insects living on the islands of Shikoku and Kyushu have noticed. Unlike other colonies, these families of termites didn't comprise males and completely consisted of female individuals. Trying to understand whether so it actually, scientists have caught several tens of individuals from each caste of Glyptotermes nakajimai and have comprehensively studied them. These "inspectorates" of colonies have confirmed that males in them weren't valid. Any individual in them wasn't the carrier of a "men's" Y-chromosome, and the body of queens didn't comprise any a hint
