The article does overplay the role that natural selection played, if you look to the original publication it's based off of, you'll see that the effects are fairly small, most of the change comes from nutrition and medicine as it has in the rest of the world, but the increase in fitness is still larger than I predicted in my answer. I'll think about this some and then change my answer. | |

Essentially, if something happened which killed some large part of the population but was significantly less likely to kill someone with a certain gene or combination of genes, those genes become much, much more fit. And many genes have side effects, for example making people shorter. So maybe Earth is struck by a highly deadly disease that happens not to kill people with a gene that also causes dwarfism or something. | |
