Again, more issues with comprehension: The authors did not know when the potentiating mutation first arose but they knew it was before generation 31,500. Figure 2 is merely figurative, being an illustration, and not quantitative. Their analyses suggested that the potentiating mutation did arise at about the 20,000 generation point or later. Their conclusion is that Cit+ mutation rate is low even in a potentiated background but apparently distinguishable from a low-incidence single, unpotentiated event.--[[User:Argon|Argon]] 15:04, 13 July 2008 (EDT)

== Statistics101 package: ==
What does the author imply by writing: "...Lenski himself does not have any obvious expertise in statistics. In fact, Richard Lenski admits in his paper that he based his statistical conclusions on use of a website called "statistics101"?
From the web site:
''Professionals: Although it was originally developed to aid students, the Statistics101 program is suitable for all levels of statistical sophistication. It is especially useful for Monte Carlo, resampling, and bootstrap applications. It has been used by professionals in many fields. These include anthropology, biology, ecology, evolutionary biology, epidemiology, marine biology, psychology, toxicology, veterinary pathology.''
It would appear that the package from the web site (not the web site itself) was used to perform the Monte Carlo resampling tests. Is there any evidence that the package produces incorrect results?--[[User:Argon|Argon]] 19:41, 13 July 2008 (EDT)
