A new report in Nature discusses research concerning the first prokaryote endosymbiosis (one cell within another).  The end result is a double membrane prokaryote.  It is likely that similar double membrane prokaryotes are responsible for the increased amount of oxygen in Earth's atmosphere.

From the summary at ScienceDaily: "We have a flow of genes from two different organisms, clostridia and actinobacteria, together," he said. "Because the group into which they are flowing has two membranes, we hypothesize that that was an endosymbiosis that resulted in a double membrane. It looks as if a single-membrane organism has engulfed another. The genomes are telling us that the double-membrane prokaryotes combine sets of genes from the two different organisms."

Honoring one's ancestors in such a way is a great tradition.  Ancient folks in the middle east area used to keep the skulls of their ancestors around for show and tell, too.  :-)
