I read that and just shook my head. Obviously a person could not fit through a seven inch opening in the cave.
Really, because there was a great documentary on PBS about three weeks ago and it focused on the team of young, thin, female PhDs from around the world who were brought together to conduct the extraction of the remains from the cave. No joke. It was rather fascinating to see them descend into the cave and squeeze through the opening. They reckoned that they were the first people down there in quite literally millions of years.
