Evolution on the table top

Started by Andrew Yates · 9 months ago

Evolution has taken another step away from being dismissed as “a theory” in the classroom, thanks to a new paper published this week in the online open-access journal PLoS Biology. The research article, by Brian Paegel and Gerald Joyce of The Scripps Research Institute, Califor ... Continue reading »

  • You seem to imply that it was in danger of being dismissed as “a theory” before this. You're right about that, but you're wrong to think this is really going to change anything. The people who reject evolution won't be swayed by more evidence. They don't care about the evidence. If they did care, they would agree that evolution is 'true.'

    But more than that, evolution *is* a theory, not a fact. It's a scientific theory, which is a step higher than facts. It takes a bunch of facts and combines them together into a single explanatory and predictive description.
  • Interesting. Where do the initial ingredients come from? How about making the machine start with nothing?
  • "Where do the initial ingredients come from?"

    From the complete paper:

    "A population of billions of RNA enzymes with RNA ligase activity was made to evolve continuously, with real-time monitoring of the population size and fitness."

    and

    "The RNA enzyme that was chosen for this study is a descendant of the class I RNA ligase, first described by Bartel and Szostak [ref]"

    Further, "Ligase" is a class of enzymes that helps links two molecules together.

    Notice: Please keep discussion on topic to biology and genomics and contribute intelligently. This isn't Digg, and this isn't Thursday's evening teen Bible study in Wichita, Kansas.
  • But he's right, a theory is higher than facts... it takes a bunch of facts and puts them together.
