People also more often have extra bones in their legs and feet, the researchers write in the scientific journal Journal of Anatomy. Evolution is said to be faster now than in the past 250 years.
Natural selection means that more people are born without wisdom teeth, said Teghan Lucas of Flinders University in Adelaide.

A vein in the forearm, which carries blood to the hand, has also been more common in newborns since the nineteenth century.
