The End of the Debate: Evolution Observed
In short, a researcher let flasks of E. coli bacteria breed over several thousand generations. They saw some really interesting changes occur:
- different colonies of bacteria independently evolved the ability to breed faster.
- different colonies of bacteria independently evolved more efficient digestion of food.
- one colony evolved the ability to digest citrate, which is something E. coli are known to NOT be able to do; their inability to digest citrate has actually been used as one of the bacteria's identifying features.
So, in short, evolution denialists are no longer allowed to:
- claim we have never seen evolution.
- claim we have no evidence of evolution.
- claim we have no record of evolution.
- claim that mutations are almost always bad, and therefore would be a hindrance to organisms instead of a help.
- claim that random mutation cannot give rise to a new trait because the odds are so low.
- claim evolution is not repeatable, and is therefore not scientific.
In short, if you don't want to be called a liar, don't lie: evolution happens, we've seen it, it can help an organism adapt to its environment, and it's repeatable.
maybe if this sig is witty, someone will love me.
