A recent study has uncovered an unexpected discovery about one of the world’s most invasive species–the yellow crazy ant. Researchers at the University of York examined the DNA of male yellow crazy ants, and found that they have no genetic variation between them. This means that all of the male ants are the same, and are likely descended from a single ancestor. This lack of genetic diversity could have caused their rapid spread across the world. The findings could have implications for understanding the spread of other invasive species, and for controlling the spread of the yellow crazy ant.
