Imagine a mum who can have children from two different species. Family gatherings would be interesting, to say the least. In the insect world, this is no joke. A new study published in Nature shows that queens of the Iberian harvester ant (Messor ibericus) routinely lay eggs of not just their own kind, but also of males of another species, Messor structor.
The researchers even coined a word for it, xenoparity, meaning “foreign birth”. It pushes the boundaries of what we mean by “species”. And this is the first known case in the animal kingdom of this happening as part of an animal’s life cycle.
