That being the case (them being unable to extract DNA from the tunnels), there are two likely scenarios.

"One is that there is an abiotic [non-living] way to create those tunnels in rock on Earth, and we just haven't found it yet," Fisk said. "The second possibility is that the tunnels on Martian rocks are indeed biological in nature, but the conditions are such on Mars that the DNA was not preserved."

Apparently they don't consider a third scenario, in which the tunnel critters were alife but not based on 'Earthly' DNA. Seems a bit narrow minded to me.

The (w)hole thing could be contamination anyway I guess.

There's the old old old story about a Pastor's note in the margin of his sunday sermon: "Weak arguement. Raise voice for emphasis."
