Lamb with 'human' face born in Russia (Video)

The lamb was born in the village of Chirka, close to the Russian republic of Dagestan.

Sheep farmer Blasius Lavrentiev, 45, had been expectantly waiting all week for his prized ewe to give birth.

But he had a nasty shock when saw the human-like creature as he was hoping to sell the lambs.

The lamb's head had the eyes, nose and mouth of a human and only the ears were those of a sheep.

Which scientific explanation suits this?
