In rare instances, DNA is known to have jumped from one species to another. If a parasite’s DNA jumps to its host’s genome, it could leave evidence of that parasitic interaction that could be found millions of years later—a DNA ’fossil’ of sorts. An international research team led from Uppsala University has discovered a new type of so-called transposable element that occurred in the genomes of certain birds and nematodes. The results are published in Nature Communications.
