Re: Dinosaur Protein



>No, why? Unlike protein, DNA doesn't seem to last longer than 100,000 years 
under any circumstances, alas. Here we're dealing with 1,000 times that 
timespan. 

So, the _B. subtilis_ cultured from > million year old amber-entombed mosquito 
was from another source?  And, why does DNA not hold up so well?
Thanks in advance.
