Do Adam and Eve have belly buttons?

Underwear Karolina Kurkova has no belly button. When the 24-year old was gracing a US catwalk for lingerie giant Victoria Secret, it was noticed that she had a smooth indentation instead. The belly button is the rounded, knotty depression in the centre of the abdomen caused by the detachment of the umbilical cord and logically everyone should have one. Surgery to correct abdominal problems like umbilical hernia or gastroschisis where a person is born with the stomach and intestines jutting through a hole in the abdominal wall may cause the absence of the belly button but in the case of Rob Swainson of Bournemouth, at least, he has a cross-shaped scar in the middle of his tummy. Now, forget about the Czeh supermodel. Spare Adam and Eve a thought. Do they have belly buttons?
