The organism is Chromosphaera perkinsii, a single celled organism that is thought to bear close relationship to early animal species. It is in a class of organisms known as dermocystids, part of a clade of eucaryotic cells, Ichthyosporea, with two branches, Ichthyophonida and Dermocystida which are generally parasites on amphibians, but in this case, the organism is free living.

This may be an example of a more complex organism that evolved into a much simpler form. That's often the case with parasites. If that's the case there was a chicken before this egg.

That's just my off the cuff remark. I'm not familiar with these species and I've not read the paper deeply.
