Wisdom About Wisdom Teeth
Did you know that some babies are being born without wisdom teeth? For many, having the four teeth removed later in life is quite common. However now, for little ones just entering the world, they don’t even have them! A study published in the Journal of Anatomy by Dr. Teghan Lucas of Flinders University says that faces are also becoming shorter and our smaller jaws mean that there is less room for teeth. The reasoning behind the change? According to Dr. Lucas, this change has occurred due to us using fire and processed foods a lot more. This new “micro-evolution” that humans are undergoing also includes a previously rare additional artery in the forearm that forms while a baby is in the womb and is the main vessel that supplies blood to the forearm and hand, but it disappears during gestation and is replaced by radial and ulnar arteries.
