Summary

Story summary

Researchers in Montpellier, France, found that Iberian harvester ant queens can produce two species from their eggs, challenging traditional species definitions.
The study in *Nature* reveals queens can clone sperm from Messor structor ants, resulting in hybrid worker ants.
This strategy, called xenoparity, allows queens to reproduce without males of their own species.
Genetic analysis indicates that only queens and some males are pure Messor ibericus, while hybrid females dominate.
Findings suggest evolutionary adaptations may threaten the species' survival due to decreased genetic variation.
