Here's the latest entry in my quest to dismiss Darwinism in as few words as possible:
"WHY GENETIC MUTATION AND NATURAL SELECTION CANNOT BE WHAT DRIVES EVOLUTION
"Mutations that contribute harm to a species' gene pool are much more common than those that contribute benefit, say 100 times as common. Individuals with harmful mutations will tend to be less successful at mating and raising young but won't be impaired enough to turn the great preponderance of harm in each generation into a net benefit: that is, instead of the efficiency of that process (natural selection) being close to the required 100% it’s probably closer to 1%. As a result, more harm than benefit will enter the gene pool in each generation, driving the species into extinction."
