Cit+ E. coli evolution ignored in Lenski website, NY Times article!
On this webpage of Lenski's lab's website, titled "Welcome to the E. coli Long-term Experimental Evolution Project Site," several areas of investigation are mentioned but the evolution of citrate-eating bacteria is not mentioned at all:
Summary data from the long-term evolution experiment including relative fitness, cell size, colony morphology (photographic), and molecular genetics.
BTW, the last time I saw that term "experimental evolution" was in the name of the Station for Experimental Evolution, which merged with the Eugenics Record Office in 1920 to form the Carnegie Institution's Dept. of Genetics. The Eugenics Record Office helped inspire the Nazis' eugenics programs, so maybe Lenski and his colleagues are Nazis.
Also, another webpage on Lenski's lab's website lists "evolution of citrate utilization" at the bottom of the page.
Also, the NY Times article mentions kinds of evolution in Lenski's lab that were far less significant than the Cit+ evolution but does not mention the Cit+ evolution:
. . . . . 12 lines of bacteria have been reproducing since 1989, when the biologist Richard E. Lenski bred them from a single E. coli. “I originally thought it might go a couple thousand generations, but it’s kept going and stayed interesting,” Dr. Lenski said. He is up to 40,000 generations now, and counting.
In that time, the bacteria have changed significantly. For one thing, they are bigger — twice as big on average as their common ancestor. They are also far better at reproducing in these flasks, dividing 70 percent faster than their ancestor. These changes have emerged through spontaneous mutations and natural selection, and Dr. Lenski and his colleagues have been able to watch them unfold.
Maybe Zachary Blount was right when he said that Cit+ evolution was not a "goal" of Lenski's E. coli experiment! LOL The Cit+ evolution is certainly not treated as a particularly important result by Lenski's lab's website and is not treated as even worth mentioning in the NY Times article.
