Bird genomes contain 'fossils' of parasites that now infect humans
The researchers found DNA 'fossils' of parasitic nematodes in seven groups of birds (clockwise): trogons, mesites, parrots, hummingbirds, hornbills, manakins, tinamous. 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.
