Fifty years of fruit fly genetic lab experiments on countless number of fruit fly have not created a new species using intelligent design combined with random selection.
If it is done in a lab it is intelligent design and not natural selection." [sic] In the following post (post 19 on that same page), a user named "Coyoteman", who has generally been opposed to creationism and intelligent design, seemed to have been confused by the post.
This was an entirely new ability for this species — an increase in complexity provided by a beneficial mutation.
This beneficial trait was then fixed in the population by natural selection.
Others see the "design" part as ongoing process which they try to fit into long-term evolutionary theory in some way or another.
Professor Lenski's experiment also causes problems for both these groups.
His research focuses on the genetic mechanisms and ecological processes that drive evolutionary change, and has attracted worldwide recognition for the immediacy of its insights into this usually unseen "force." He is also interested in the development of digital organisms using the They reported that, as a result of several beneficial mutations, his organisms had acquired the ability to metabolize citrate — or more correctly an ability to transport it through the cell wall prior to metabolizing it.It is also important to notice that before acquiring this ability the bacteria acquired a previous potentiating mutation which, although it was not clearly beneficial at the time, subsequently allowed the descendants of that potentiated group the ability to process citrate after a further mutation.Furthermore frozen ancestors of that group, and only the frozen ancestors of that group, retained the ability to re-evolve that favorable trait.It came as a fair shock to the researchers that the E.coli developed the ability to absorb the citrate medium (described in the popular literature as the bacteria not having enough to eat, so they evolved to eat the plates and cutlery instead).
