Evolution@home has quantified Muller's ratchet in the worm C. elegans

The small worm Caenorhabditis elegans is known for his high rate of selfing that may make it susceptible to the operation of Muller's ratchet. Now evolution@home has found that this worm would indeed be in trouble if there were no processes that would counter genomic decay in this worm or if selfing was very old.
