Johannesburg - A baby girl was born at the Cradle of Humankind on Friday while her mother was on a tour of the world famous Sterkfontein Caves.ER24 paramedic Pieter Rossouw said while the mother was touring the caves, part of the Maropeng World Heritage site outside Krugersdorp, she felt a sharp shooting pain in her abdomen. She went into deep labour and paramedics were called.''When they arrived on scene they found a beautiful baby girl had been born,'' a delighted Rossouw said.The girl was premature, but in good health.Maropeng acting general manager Lindsay Marshall said tour guides were trained in first aid so Motlhatsi Mochela, Onica Kekae, Lindiwe Mahlangu and maintenance man Jacque Deysel sprang into action as midwives and helped the mother safely bring her daughter into the world.''I think any birth is a special occasion and especially in the Cradle of Humankind,'' Marshall said. ''We will follow up with mother and baby to see if they are okay. The situation was handled very well.''The United Nations Educational, Scientific and Cultural Organisation declared the Cradle of Humankind, including Sterkfontein, Swartkrans, Kromdraai and its environs, a World Heritage Site by the UN Educational, Scientific and Cultural Organisation. Maropeng said this was important as it told the world about our ancestral species and their relatives known as homonids.The most famous fossil was "Mrs Ples", a skull estimated to be more than two million years old, and the skeleton ''Little Foot" estimated to be between three and four million years old.
