Hum,
Reported Here First:
it seems that evidence for indigenous microfossils in a carbonaceous meteorite have been found:
The possible detection of a fossilized cyanobacterial mat in the interior of the `Orgueil carbonaceous meteorite` was disclosed at the International Symposium on Optical Science and Technology in Denver, Colorado.
Microfossils in meteorites, of course, have been reported before, with critics saying that they may have been left by earthly contaminants. But the newly seen microfossils cannot be contaminants because they are not isolated single cells, but whole ecologies whose earthly examples grow only under conditions that the meteorite fragment never experienced on Earth.
The new evidence, soon to be published in the Conference Proceedings, is momentous.
