voice 2: But other scientists explain the problem in a completely different way. Dr Stephen Jones is a professor of genetics at University College London. He agrees that the problem is genetic in origin. But he says, 'You cannot say that because people walk on their hands and feet they must represent a link to animals such as apes'.
Dr. Jones believes that other facts combined with the genetic problem. He thinks the two things together have caused the sad condition of the Ulas children.
voice 1: Mr and Mrs Ulas are very close relations. Two people like that can be in danger of producing unhealthy children. Mrs Ulas had seven children in the space of five years. It is possible that this would cause the children to be weak. The Ulas family live far away from a town or a city. There was no-one to help their sick children when they were born. These facts could easily explain why these young people have suffered such tragic lives.
