Mars Bacteria ???
This meteorite:
Found in Antarctica 1984 by meteorite hunters
Ejected from Mars by meteoritic impact and fell to earth ~13000 years ago
Comes from Mars proven by gas composition of inclusions
There are 14 mars meteorites known (out of 20000)
Indications of life 3.6 billion years ago:
The discussion:
Each item itself not convincing - can easily be produced by
non-living chemical
processes (as partially has been shown later)
As a sum ??? very controversial .... - contamination from earth, some features
indicate
high temperatures not compatible with life
1998 "killer": shown that minimum size for something living (with DNA)
is 0.2 micrometer
2000: french scientists find traces of earth bacteria in meteoritic fragments,
that are of same
size than mars
"bacteria"
maybe bacteria fragments or
"shrunk" bacteria
Summary: meteoritic findings most likely not connected to life on Mars
