'''Richard Lenski''' is a professor of microbial [[ecology]] at Michigan State [[University]].  He holds a [[doctorate]] from the [[University of North Carolina]] and a B.A. from Oberlin College but does not disclose his fields for those degrees on his own biographical sketch.<ref>https://www.msu.edu/~lenski/</ref>

<font size=10>RICHARD LENSKI IS THE MAN.  ANDREW SCHLAFLY IS A HACK.</font>
−
 
 
−
Richard Lenski is best known for his questionable claim to have observed the [[theory of evolution]] in practice, saying that [[E. coli]] bacteria made minor changes in a long-term laboratory study, and insisting that it was not due to contamination.  The 2008 paper he co-authored was [[peer review]]ed in a mere 14 days, sparking obvious questions<ref>See [[Conservapedia talk:Lenski dialog]].</ref> about the thoroughness of the review.
 
−
 
 
−
When challenged, Lenski displayed several examples of irrational [[Professor values|behavior]], thrice referring to the challenges as [[slander]], yet has filed no [[lawsuit]] charging that (or [[libel]]). [[Truth]] offers total legal protection from accusations of libel. He has also displayed annoyance, arrogance, and [[elitism]] when asked to release the information.<ref>See [[Conservapedia:Lenski_dialog#Second_reply|Lenski's second reply to Andrew Schlafly]]</ref>
 
−
 
 
−
When Richard Lenski received a public request for the [[data]] underlying for his published claims, he did not provide the actual data even though his study was taxpayer-funded. Lenski's refusal to provide the raw data even to fellow [[Darwinist]]s is telling, and makes it clear that he will not allow his claims to be tested by [[Creation science|open-minded scientists]].

These contaminated cultures reach much higher turbidity owing to the high concentration of [[citrate]] in the medium, which allows the contaminants to reach high density. (When contamination occurs, the affected population is restarted from the latest frozen sample.)

A Richard Lenski defender says, "If interested in a thorough review, contact the group directly, with a legitimate request for data.  Otherwise, the disclaimer is a more than adequate description of the sample handling process."

In fact, two requests were made directly to Lenski for data, without success. His [[Conservapedia:Lenski dialog#Second_Reply|second response]] was rude and insulting.

A Richard Lenski defender also cites an earlier claim (perhaps also unsupported by public release of the data) by Lenski's group: See also the reference for the sequence identification which Blount ''et al.'' list as reference #30 in their paper: Woods, R., D. Schneider, C. L. Winkworth, M. A. Riley, and R. E. Lenski. 2006. Tests of parallel molecular evolution in a long-term experiment with Escherichia coli.

The astoundingly short 14-day [[peer review | PEER REVIEW]] period, measured from the day the paper was sent out for review to the day of formal contribution by Lenski after acceptance, raises questions as to whether there was any meaningful peer review of this at all.

Lenski's paper was published in the Proceedings of the [[National Academy of Sciences]], a professional society of scientists with a strong bias towards [[atheism]] and [[evolutionism]]. <ref>http://www.stephenjaygould.org/ctrl/news/file002.html</ref> <ref>http://www.answersingenesis.org/docs/3506.asp</ref>

−
Lenski's work has been criticized in the past also.  In a paper Lenski published in ''Nature'' in May 8, 2003 entitled "The Evolutionary Origin of Complex Features," he described a computer simulation that contained no actual biology.  In fact, the discussion section of the paper stated:
 
−
 
 
−
:"Some readers might suggest that we 'stacked the deck' by studying the evolution of a complex feature that could be built on simpler functions that were also useful. However, that is precisely what evolutionary theory requires ...."
 
−
 
 
−
Dr. William Dembski explained, "In other words, the computer programmers built into the simulation what they thought evolution needed to make it work. The validity of this study therefore depends on whether the simulation faithfully models biological reality."<ref>http://www.designinference.com/documents/2003.09.UncDiss_Intro_Contribs.pdf</ref>
