Yellow crazy ant males have two sets of DNA

A small international team of molecular and evolutionary scientists has discovered that male yellow crazy ants (also known as long-legged ants) have two sets of DNA throughout their bodies. In their paper published in the journal Science, the group describes the unique find and discusses possible reasons for it. Daniel Kronauer with The Rockefeller University has published a Perspective piece in the same journal issue discussing the work by the team and suggests that the unique genetic feature of the ants may explain why they are such a successful invasive species.
