Humans are undergoing a “microevolution” resulting in babies being born without wisdom teeth and with an extra artery in their arm, according to Australian researchers.
The scientists believe humans are evolving faster than at any point in the past 250 years — with more babies coming out with shorter faces, smaller jaws and extra bones in their legs and feet.
The stunning findings were part of a study in the Journal of Anatomy.
The extra artery is a median artery that’s first formed in the womb and serves as the main vessel that supplies blood to the forearm and hand, according to Sky News. The median artery vanishes once the radial and ulnal arteries develop, though now one in three people keep it for life.
