That’s odd, because they look like anatomically-modern humans awkwardly walking around on all fours. They walk on their palms rather than their knuckles like chimpanzees, gorillas, and the earliest human ancestors, and the arm-to-leg length ratio is completely wrong for quadrupedalism. The transition to bipedalism affected almost every bone in the skeleton and involved mutations in many genes. The idea that this could be undone by a single mutation is patently absurd. What happens if advocates of eugenics get ahold of this story? They might argue that the victims of this disorder are at least a million years behind the human race and are therefore not really human. it would not be much of a stretch for a neo-Nazi to switch from thinking of these people as “ape-like” to simply “apes” which can be killed to purify the human race.
Finally, I’d like to point out that the International Journal of Neuroscience has had problems with not fully refereeing papers submitted by members of its own editorial board. For example, check the controversy surrounding the creationist Dmitri Kuznetsov and his paper which, amongst other things, referred to papers or journals which did not exist.
