Thank You, Parasites!
Without you, we might never need to have sex! Next time I meet a tapeworm, or a scabies mite, I intend to buy it a pint!

Amen, brother...Sex has long troubled evolutionary biologists.
And, given that the species of worm was Caenorhabditis elegans, the following quote is Ratz worthy...
But seriously folks, a very solid chunk of evidence for the evolutionary background to being randy...Dr Agrawal described the experiment as "elegant" because it allowed the researchers to demonstrate that it was not simply the presence of the parasite that spelled the end for the cloners, but the presence of a parasite that had co-evolved alongside the worms.
Well spotted, XC...

Re: Thank You, Parasites!
I'm not sure how valid the results are.
When you alter how a worm reproduces artificially, the resulting offspring might not be as viable as those that reproduce naturally.
These worms have evolved to reproduce sexually, you don't know what other effects cloning has.
I would have done the test not by cloning, but by freezing some eggs, and allowing others to reproduce for a few generations sexually.
Then compare the results of the worms that had skipped a number of generations, to those that had supposedly evolved.
If there was a clear difference, then you COULD claim that sex had helped evolve resistance, and not that the cloning process itself had caused the problem.
Basically, I think that organisms that reproduce sexually NEED to reproduce sexually to stay healthy, because of hundreds of millions of years of getting used to it.
Things that have always cloned, will have mechanisms that keep their populations healthy.
Otherwise, they wouldn't be around.

Re: Thank You, Parasites!
This ability to evolve quickly in response to a problem is probably a great advantage to animals like worms.
Higher animals can walk, swim or fly out of a difficult environment. Worms have to make the best of the environment that they find themselves in. So if they find themselves in a place where the bacteria are particularly virulent, they can quickly produce a population that can handle it.
I remember an evolution video, I think it was Dawkins, where they looked at an old mine area, heavily contaminated with arsenic, where the worms had evolved to handle it within less than a hundred years. Cloning just wouldn't stand a chance of populating that soil with worms in probably a thousand years.
