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 insisting 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> Opponents argue that during strategic points in the experiment, Lenski contaminated the flasks with exactly the right type of E. coli to fit the mathematical models one would expect to see in an evolving population. He then inexplicably made the mistake of admitting to contamination occurring when when questioned by these opponents.

When Richard Lenski received a public request for the [[data]] underlying his published claims, he did not provide the actual data even though his study was taxpayer-funded and even though the request was made in part to enable review of the data by students of the requestor, although he did offer to provide the data (strains of the ''E. Coli'' bacteria) to an experienced scientist with access to a laboratory able to handle it. <ref>[[Conservapedia:Lenski dialog]].</ref>
