New research reported by Earth.com suggests transposons, so-called jumping genes, may explain how ants diversified rapidly after the dinosaurs went extinct 66 million years ago. The finding points to these mobile DNA elements driving genetic variation that allowed ant species to adapt and spread into many ecological niches, helping make ants one of the most successful insect groups on Earth.
