Richard Lenski claims that his experiment provides “one of the most direct demonstrations of Darwinian adaptations by natural selection you can imagine.”
Perhaps the biggest evolutionary development in the course of the experiment involved some bacteria beginning to feed on citric acid.
“There have been no mutations…identified that appear to be on their way to constructing elegant new molecular machinery of the kind that fills every cell.”
Shhh — don’t say it. The geological event, well, not “event,” as in something that happened about 541 million years ago…we don’t talk that way anymore.
Evolution is good at creating niche advantages by breaking things; it isn’t good at building fundamentally novel forms.
