Busy goings on at UD today. First Dr. Dr. D. plugs a new programme, reveals that he's finally got a paper accepted, and also complains that there's too much politics and not enough science ID.
In response, Dave decides to try and sound sciency, with inevitable results. The biologists amongst you, in particular, will find this amusing. As I'm back in moderation, I'll leave my comments here as well:
| Quote | Dave - you're comparing apples and oranges. Lenski and co. were looking at the evolution of a new function - at the start of the experiment the bacteria didn't have any genes for lactose digestion.
In the paper you cite here, Xie looks at induction of genes that are already present. His <i>E. coli</i> strains already have the genes for lactose digestion, so there is no evolution. What he is looking at is the details of how expression of the genes is triggered, not how these genes originate. |
