We collected "fecal" material during both the 2007 and 2010 expeditions. The 2007 sample, which was not collected with sterile protocols, had what appeared to be Ric's DNA in it. I think it is the 2010 sample that has recently been tested that has the two different human DNA traces in it. Ric could set me straight on this.
So, the 2007 sample was either Ric's poop, or contaminated by Ric's handling it excessively (lots of us handled it not knowing it was going to be tested). Whether or not the 2010 sample has been matched with Ric's DNA remains to be seen, but the fact that it has what appears to be the human DNA from two persons is very interesting. Either we have Ric's DNA and someone else, or even two unknown persons. Will be interesting if any of the sequences matched the Earhart family sample we have.
