Thank you Cofty!!!! I have been looking for something like this !
My best, best childhood friend is a witness( out of devotion to her parents, a misplaced loyalty basically) and an audiologist. In fact she runs the whole dept , the largest in the county,and he a Msc qualification ( the smartest kid in a school that sent many kids to OxBridge, she dutifully attended community college where this course was the most ' academic'). Of course she's shot to the top in her field.
I always thought the human inner ear was one of those areas creationists harp on about and I vaguely had heard of the jaw bone theory but this is beaut.
My girl is one of the witness 3% with a masters or above, but I fear she decided as a young girl when her mum converted in the 70's ( as did her similarly intelligent dad) to stick with those she loves no matter what.
Her pioneer mum has now passed away, perhaps now is my chance.
