Summary

Story summary

Researchers found that Messor ibericus ant queens can produce male offspring from both their species and Messor structor, a process called xenoparity.
This strategy allows queens to clone males from another species, challenging traditional reproductive views.
Hybrid workers emerge from the genomes of both species, crucial for colony function.
Queens can discard their nuclear DNA from eggs, using only stored sperm from Messor structor.
The study, published in Nature, raises questions about species boundaries and evolutionary implications.
