Since life originated on Earth about 3.8 billion years ago, Pavlov does not believe that there has been enough time for this resistance to evolve.
Foolish. A dose of radiation accumulated over a few days or weeks would not have the same effect as the same dose over a hundred million years. Besides, if that's all it took, all life would exhibit a similar radiation resistance; our cell line certainly reaches back hundreds of millions of years, too. The radiation resistance is most likely the by-product of another evolutionary pressure.
Silly. That's precisely the point of the statement in the article.
