why? weve known about meRNA and miRNA based vesicles for years and the concept of an "RNA world" appears to be closer to being confirmed with some of this.
This is not new or surprising news btw. "Capturing genomes" was hypothesized many years ago, and "common ancestry" (a LUCA) among the Plantae and Animalia, is knowledge that Venter proposed years ago and LANE and others are publishing like madmen. Im almost certain that Investigations into "What is the LUCA" can utilize these data. To most recent work "genes are easy" but pumping 10^21 protons per second through vesicles makes the RNA world more understandable.
Margulis, in 1967 proposed endosymbiosis among eukaryotes and protista (serial endosymbiosis to be more exact)
