Changes

Richard Lenski is best known for his 20-year E. coli experiment in which he claims to have obtained proof of [[evolution]].  Lenski claims that he observed minor changes in bacteria populations in the long-term laboratory study, while stating that genetic markers common to ancestral and evolved samples demonstrate that these changes were not due to contamination.

The 2008 paper he co-authored was [[peer review]]ed in 14 days, sparking obvious questions <ref>See [[Conservapedia talk:Lenski dialog]].</ref> about the thoroughness of the review.  The statistical analysis in Lenski's paper has been criticized for several serious flaws.<ref>See [[Flaws in Richard Lenski Study]].</ref>

When Richard Lenski received a public request for the [[data]] underlying his published claims, he stated that the data was contained in his published papers about the experiment, and offered to provide the physical evidence (strains of the ''E. Coli'' bacteria) to an experienced scientist with access to a laboratory able to handle it. <ref>[[Conservapedia:Lenski dialog]].</ref>
