Summary

Story summary

Iberian harvester ant queens can produce offspring from multiple species, challenging traditional biological concepts.
They use sperm from Messor structor to create cloned males, bypassing nuptial flights.
Offspring include both M. ibericus and M. structor, sharing maternal lineage.
M. structor males are clones, retaining only their father's DNA.
This study reveals sperm parasitism, reshaping our understanding of evolution and species interactions.
