The experiments I have referred to in previous posts were CT scans made in 2007 on a Frenchman had had hydrocephalus as a child. I described it in a previous publication thusly:
In 2007 a 44 yr. old Frenchman, who was diagnosed with this condition as a child, was examined by physicians for a slight weakness in his left leg. Upon taking a CT scan of his brain, they were amazed that the ventricles were so enlarged that what remained of his brain was only a thin sheet adhering to the skull. (See illustration) (5) Although his I.Q. showed some impairment, he was married, had two children and had been leading an entirely normal life. In other words, he was operating as a modern human while having far less than half of the brain capacity of one of our ancient ancestors, Lucy, the famed Australopithecus afarensis who lived 3 million years ago.
Unless this is some sort of hoax, I think it has great significance in determining how we became human through evolution.
