Researchers at the Max Planck Institute for Biology in Tübingen have produced the first sound evidence that the teeth of the nematode Pristionchus pacificus consist of chitin. In doing so, they not only answer the long-standing question of the teeth composition, but also open up new perspectives on the evolution of the up to 10 million nematode species. Their results now appear in the journal Current Biology.
