Re: A Harry Mcsween lecture, and life in a Martion meteorite.
Although this subject has been discussed for awhile I'd like to bring up
some rather 'non-scientific' questions I have!

Is he suggesting that the sample was contaminated on entry to our
atmosphere, while resting on the ice, or during testing? Do most
terrestial rocks show this contamination as well?

I know this will sound a bit 'wacky' to all of you scientists but here
goes (I'm not a biologist!) ... Why do we expect 'supposed' life on
another planet to follow the exact same 'rules' that it does on earth,
when the planet's attributes are very different? Isn't it 'possible' ,
due to the different atmosphere, temperature, gravity, etc.., that life
could develop slightly differently? OK, enough of my 'x-file-ish'
rantings!
