Researchers just discovered a method of animal reproduction previously unknown to science, reporting that a biological law is being “broken” by a species of ant.
“The discovery is quite extraordinary,” said Denis Fournier, an ant biologist at the Université libre de Bruxelles who was not involved in the research. Pinpointing the ant’s novel form of reproduction, he added, offers “yet another glimpse of what nature is capable of inventing.”
As a result, the bodies of male yellow crazy ants are not composed of cells containing the same set of DNA. The male ants are instead made up of two cell lines each with its own distinct genetic lineages — one from the queen and the other from her mate.
A male yellow crazy ant represents what scientists call a chimera, or a single animal with two sets of genetically distinct cells. The name comes from a Greek mythological creature that is part lion, part goat and part serpent.Scientists have found a handful of chimeras in nature, both in humans and other species, sometimes resulting in people or creatures with two different colored eyes.
