Lenski’s new results; Behe’s red herring

Richard Lenski is an evolutionary biologist who studies evolution by analyzing changes in bacterial populations.  Perhaps he is most famous for his long-term experiment where his group identified a population that evolved to use a nutrient (citrate) that E. coli normally can’t use.  This was a very important finding as it provided proof-of-concept that random [...]

Lenski vs conservapedia

No self-respecting evolution blog can go without mentioning the interactions of Dr. Lenski (of evolution in a tube note) with Mr. Schlafly of Conservapedia. Conservapedia is the religious right’s answer to Wikipedia, because they believe that Wikipedia is biased toward liberal ideas.
Mr. Schlafly (a non-scientist) sent a letter to Dr. Lenski to

The evolutionary numbers game

In my last post, I brought up how Michael Behe used the fact that 40,000 generations of E. coli were necessary for Richard Lenski’s experiment to find an E.coli who could utilize citrate. In this post, I am going to run through some numbers to show how 40,000 generations is nothing to evolutionary time.  [...]

Behe Doesn’t Believe in Evolution in a Tube

Michael Behe writes on June 6th a post entitled: Multiple Mutations Needed for E. Coli. This post came from his amazon blog, where he is trying to push his book. Behe is writing of course about Richard Lenski’s (et al.) recent publication in PNAS (Proceedings of the National Academy of Sciences). In the [...]
