Arlin makes a good point here.  When trying to explain a complex point, 
any instructor or textbook auther must make a coherent presentation out 
of what are usually conflicting data sets.  I used to say of one of my 
professors in grad school that he presents a beautiful picture of the 
cell--considerably more beautiful than the facts can support.
I think the best one can hope is to make one's bias clear so that the 
student has some basis for criticism.

Quoting from the Preface of "Molecular Biology of the Cell" (Alberts et 
al.)  "But these unsolved problems provide much of the excitment...
Thus, rather than simply present disjointed facts in areas that are 
poorly understood, we have often ventured hypotheses for the reader to 
consider and, we hope, to criticize."

Having said that, there does seem to be some crony-ism in the way the 
hypotheses are selected for any particular unresolved area.
And, perhaps for those who don't read the preface, it should be made 
more clear in text where the areas of confusion are. 
I would suggest that people should not be so surprised that there are 
statements in textbooks that are biased, or just plain wrong.
