They believe there are multiple inconsistencies with this scenario, one of them being the fact that radiation resistance is not induced in bacteria that have undergone cycles of dessication. But instead of iterating their arguments, I will give you the reference:<BR/><BR/>ANATOLY K. PAVLOV,1 VITALY L. KALININ,2,* ALEXEI N. KONSTANTINOV,2<BR/>VLADIMIR N. SHELEGEDIN,2 and ALEXANDER A.

Both desiccation and radiation break D. radiodurans's chromosomes into short DNA fragments. Radman and his colleagues blasted the microbe with one megarad of gamma radiation, enough to sterilize food but well below D. radiodurans's resistance threshold. Nevertheless, its chromosomes broke down into short strands of DNA. For the next hour and a half, the cells appeared dead, but by the end of three hours the chromosomes of D. radiodurans were reassembled and fully functioning.<BR/><BR/>Well, that is the thing with panspermia. Any scientific fact can then be re-engineered to sound like it is made up to support panspermia or vice versa.Born a Libranhttps://www.blogger.com/profile/14179849395244410265noreply@blogger.comtag:blogger.com,1999:blog-4563068268982660612.post-91758137904406941992007-05-24T08:18:00.000-07:002007-05-24T08:18:00.000-07:00One recent paper provided possible support for pan...One recent paper provided possible support for panspermia by investigating the bacterium <I>Dienococus radiodurans</I>, which can withstand ungodly measures of radiation. The hypothesis is that at no time in the history of the earth were radiation levels so high that the bacterum actually needed to evolve such radiation resistance. Thus, one plausible hypothesis to support this observation could be that Dienococcus evolved on Mars and was transported to earth.<BR/><BR/>Francis Crick was a man who was known for being unusally prescient and right.
