Taking this seriously :wink: I'd think the question is spurious until we find good evidence, as are chemical signatures, that life existing on Mars, if there ever was such a thing there, is related to life on Earth.
Until then questions such as these are better seen as diversions from the main subject that is the appearence of life on Earth as it's useless to ascribe our origins to other planets when there is little evidence for it.

Panspermia itself is tricky business, 'cause a life form has to be sufficiently lucky and/or specialized to resist either coming as dust or bolide. I wouldn't put much validity in it.

Sorry...

I'm from Planet Earth. A stranger, more exotic, more changeable, more
inconceivable planet you will find no where else in the known universe.

I was born on a living starship in an alternate universe. Being a cell from a living starship in an alternate universe is waaaaaaaaaay better than anywhere ya'll were born. :wink: :P

Panspermia is always misunderstood as some theory that hints that "some form of already developed-embryonic or living orgranic 9common shared ancestor- travelled here incubated or frozen in a block of ice (comet) which may or may not have landed on earth but passed close enough to excrete it's contents here, which developed to the life we see today"

That is NOT what Panspermia is about. The theory in fact is more subtle and suggest that a non-organic "prime mover" or extra-solar object arrived near earth and caused the chain of events that assisted in terrestial evolution. Viruses, DNA, RNA are all prime candidates. There is even a far fetch theory I read a while back in a science journal that the Mitachondria, a crucial catalytic component found in living cell of apparantly unknown origin, may even have been involved in a past terrestial panspermia event that gave rise to Eukarya chain of organic terrestial beings (everything on earth except bacteria and archaea).

I'm not sure if this topic was a joke...
but justice must be done for the trepid scientists who courageously procured the theory decades ago and the science fiction authors(namely Clarke & Baxter) that popularized it.

Larry Niven....
I never remembered manholes in "Integral Trees" and I dont recalled ever finish reading the "Ring World" books...then again I read those when I was in the third grade and I'm in college now so I cant say...

so you got me buddy,
*sigh*
whats the deal with the manhole covers being chocolate covered?

and this better not be a bad gay joke either....

OK, I'll put you out of your misery...

"What can you say...." is a short story by LN which starts with describing a guy who turns up at parties and askes random questions like: "What can you say about CCMC?" or: "Hey, suppose ALL the Adam and Eve legends were true".

It's this last question which is the subject of the story.
To cut to the chase... in this story Niven explores the possibility that the human race was "planted" and is being selectively bred like racehorses by an overlord race of super-beings.

I read a similar story somewhere else. Clarke's 2001 Odyseey and Baxter Manifold Spacealso have more subtle implications to the P theory.

I will try to read that LN story though. It sound good.
Thanks SlaverStudent.
