Why people yawn is a mystery. But yawning starts in the womb.
Past studies have used ultrasound images to show fetuses yawning, but some scientists have argued that real yawns were getting confused with fetuses simply opening their mouths.
So Nadja Reissland, a researcher at the University of Durham in the United Kingdom, used a more detailed ultrasound technique to get images of fetal faces that could distinguish a true yawn from just an open mouth.
Or, more accurately, making sure Hegge Jeanette Oksnes has recently given birth — or is just about to.
Last week, her brother, 19-year-old Tord Oksnes, won 12.2 million kroner ($2.12 million) and became the latest member of the Oksnes family to win Norway's national lottery — a few months after his sister gave birth to her third child.

Babies are lovely but altogether helpless creatures.
Wouldn't it be better if tiny humans were born able to walk, like horses, or generally were readier for the rigors of the world, like, say, chimps?
Among primates, human have the least developed brains at birth, at least when compared to adult human brains. If humans were born as far along on cognitive and neurological scales as rough and ready chimps are, though, human pregnancy would have to last at least twice as long. Eighteen months in the womb, anyone?
