[quotations from a Felsenstein paper pointing out that the simple 
 explanations of the evolution of sex are inadequate and that sex is
 a difficult problem for evolutionists]

Sorry, I didn't mean to imply that you (and others) don't have educated
guesses concerning the orign of sex. (Perhaps hypotheses would be a better
term?) The problem is to determine which, if any, of these hypotheses is
correct. However, the main point that you make is that the question is far
from solved and you mentioned that the simple textbook explanations are
not likely to be correct. I wanted to post your comments because it
directly refuted the claim that the explanation of sex was easy and could
be found in any textbook.

I didn't think that you would respond to the original article. I was 
trying to indicate that some very smart people have concluded that sex
is a problem. BTW, this compliment doesn't imply that I agree with all
of your hypotheses ....   (-:

Yep, .... and some of them are interesting while others are very likely
to be wrong. Hence, we have a problem with sex.
