Ants are amazing. From Smithsonian Magazine

the M. ibericus queens store the M. structor male’s sperm, then use it to fertilize some of the eggs they lay. Researchers think the M. ibericus queens remove their own genetic material from the eggs’ nuclei, so that when those eggs hatch, they effectively turn out to be M. structor male clones. … Even more perplexing is the fact that M. ibericus and M. structor are not closely related, evolutionarily speaking. The two species diverged more than five million years ago … Even more intriguing, the males of both species shared M. ibericus mitochondrial DNA, which is inherited from the mother, suggesting they had all been born from M. ibericus queens.
