A good example of bad news reporting (Score 1)

The article doesn't describe a mutation. A mutation is a genotype change -- a change in genes, in DNA. What the article describes is, at best, a phenotype change. Due to the particular environment of folks in modern societies, their thumbs have become more dexterous. I don't think that any reasonable observer of industrialized society finds it shocking that folks who play a lot of video games have agile thumbs -- but it is not a mutation in any sense of the word. The conflation between a genotype and phenotype are pretty common in so-called science journalism.
