I reworked the paragraph in question to read:   

 :"The key contention of creationists is that evolution is not sufficient to account for diversity of life.  This view is overwhelmingly rejected by the scientific community and academia, ; ; ; ;  and how, as in the title of a famous essay by Theodosius Dobzhansky, Nothing in Biology Makes Sense Except in the Light of Evolution.  

 Which I think is accurate, and fits nicely in the article.  It does however shift the "key" creationist contention from evolution not being able to explain the origins of life (which, I think, it is not claimed to explain) to evolution not being able to explain the diversity of life (which is what evolution explains, at least as I understand it.)  E.g., see my observation above regarding a comet bringing life to Earth.  If this observation were ever established in mainstream science, it would not affect evolution, except, perhaps, raising the possibility that life may have had more than one origin (comet impact). 

 I fully admit that I could be wrong in this summary, and would appreciate correction.
