Evolving to evolve? Evidence that contradicts Darwinism
|November 19, 2013||Posted by News under Darwinism, Natural selection, News|
Or neo-Darwinism. Or whatever they are calling it now. Here:
The idea of evolution driving evolvability is “highly controversial,” the team, including biologists from the University of Pennsylvania and the University of Kentucky, wrote in their paper, published in the journal PLOS Pathogens. Although many quickly evolving creatures are successful, it seems strange that evolution should build that into organisms. After all, evolution should be as blind to the future as your local psychic (Sorrynotsorry). Natural selection selects for traits that are useful right now. Sometimes those traits happen to be useful to later generations in unexpected ways, but there’s no mechanism in evolution to actively prepare for the future, which is what evolvability does.
Nevertheless, to look for some real-world evidence of selection acting on evolvability, the Pennsylvania and Kentucky biologists examined Borrelia burgdorferi, the bacteria species that gives people Lyme disease.
We are assured, however, that organisms more complex than microbes cannot evolve to evolve. Formerly, we were assured that it couldn’t happen even in microbes, and that that claim is the most powerful idea ever:
And like all the best ideas it is beguilingly simple. In fact, it is so staggeringly elementary, so blindingly obvious that although others before him tinkered nearby, nobody thought to look for it in the right place. – Richard Dawkins, 2010

“It makes a lot of sense that organisms should be predisposed to dealing with future environments, but when you get down to thinking about how this might come about, it’s not so obvious,” says Paul Rainey, an evolutionary geneticist at the New Zealand Institute for Advanced Study in Auckland and the Max Planck Institute for Evolutionary Biology in Plön, Germany. “These guys show quite clearly that natural selection can lead to the evolution of types that have a greater capacity to respond to future environments.”
But rest assured, if you like your Darwinism, you can keep your Darwinism. We’re not going to just up and change it on you.
