Vanilla Forums has been nominated for a second time in the CMS Critic "Critic's Choice" awards, and we need your vote! Read more here, and then do the thing (please).
Our new Indie Games subforum is now open for business in G&T. Go and check it out, you might land a code for a free game. If you're developing an indie game and want to post about it, follow these directions. If you don't, he'll break your legs! Hahaha! Seriously though.
Our rules have been updated and given their own forum. Go and look at them! They are nice, and there may be new ones that you didn't know about! Hooray for rules! Hooray for The System! Hooray for Conforming!
Scientist grows twelve separate colonies of bacteria in the lab, all derived from the same original cell; One colony evolves a radical new trait after 35,000 generations. To test this, the said scientist uses "backup copies" (staples from the colonies frozen every 500th generation) to re-wind the evolutionary path.
the conclusion is that only the one particular colony ever had a chance of evolving the new trait and only because of something that happened to it's 20,000th generation, 15,000 generations before the radical new mutation appeared.
As if we needed it, more proof of evolutionary principles. At least we now have a testable model for examining evolution.
I want to know what the reaction if the ID/creationism crowd will be; I fully expect dismissal, but what form of dismissal exactly? I can think of at least one variation; "it's a laboratory experiment, this is no more natural than pocket watches!"
Anyway, I thought that this was a fascinating little experiment that at least some of you guys would want to know about.
