I appreciate the discussion of the Mars fossils. My thoughts on various people's comments: 1. I think some of the media were trying to contact paleontologists but just did not know where to go. I actually had a call from Italy about them, and there were a few others. (No, this time I did not say anything!!). A second problem we recognize is that few paleontologists are qualified to evaluate bacteria or bacteria-like fossils. Given that the media did not know where to go, those that tried went to where paleo was easily identified--dinosaur people, museums of paleontology, etc. How do you find a bacterial or extraterrestrial fossil specialist if you are fairly ignorant? 2. The news releases I read seemed to concentrate more on the source and the geology of the find rather than the fossils. Fossils were subsumed by the biology and "life", neither of which terms necessarily would evoke paleontology in the poorly-informed minds of the media. So I am not upset that more paleontologists were not contacted--the media did their best, and once again it was pathetic. That goes for most of the PR people that NASA and NSF have working for them too. I have never been so misrepresented as I was by an NSF Press Representative. If paleontologists are to have their opinions known, then they should react to news releases immediately themselves by calling their local media. We need a media contact point within the societies too. The media would welcome it, I am sure, because they want something to say and they often will take almost anything (like a dinosaur paleontologist bs-ing about Martian bacteria-like objects). 3. We expect that life on another planet might not look like terrestrial life. However, if fossil life could be transported from Mars to Earth or visa versa by an impact 15 mya, then the possibility that life was transported in the very distant past might not be so ridiculous. Maybe the early forms were, in fact, transported to various parts of the Solar System in the waning times of major impacting, say 3.5-3.0 bya. Panspermia--oh, horrors. Then the early stuff is all related!! 4. Life might well look very similar in its early stages of C-based evolution. It seems likely to me that given the amount of C and H compounds calculated to have been brought to earth by early impacts, that any planet with impacts and water could develop C-based life, at least to an early step, like something like bacteria. 5. In fact, Jack Farmer, a NASA paleontologist, already coined the term Exopaleontology for the discipline we are discussing. He did it as part of the Martian Lander planning team, and he was responsible for selecting several potential sites near what appear to be hot-spring deposits on Mars that look like Yellowstone hot springs. Here stromatolites and mats might be found. So NASA already has plans based on exopaleontology. Unlike Exobiology, Exopaleontology may have, at least, discovered its subject! 6. I wonder if NASA was a bit surprized by all the hoopla over this finding. Any normal scientist would think this was a really interesting and exciting bit of discovery that supported the "life" hypothesis but that many tests remained to be done, any of which could disprove the hypothesis. I sure hope NASA would not be so stupid as to throw out this kind of tenuous hypothesis with the idea that it would provide funding. Surely, they could see the potential for getting burned in a major way here. This could be a disaster for NASA just as well as a windfall. Just too many questions. Bill Schopf has already raised serious ones. There are others too. Unless, of course, all this is planned by one of those silly PR types I referred to above. 7. On the other hand, this has the potential to do wonders for paleontology. Like dinosaurs, everyone is interested in extraterrestrial life. So, even if it gets disproved or is questionable, I think we should make our own hoopla over exopaleontology, if not for additional funding, then as a tool to improve scientific reasoning and discipline visibility.
