This is a true statement. According to Miss Gabby Bisset from Dentistry Online, the human race is passing through a microevolution with babies being born without wisdom teeth as proof.
New research has emerged from the Journal of Anatomy study that showed babies have shorter faces which in turn leads to smaller mouths/smaller jaws and less room for teeth.
This source cites Dr.Teghan Lucas, from Flinders University, Australia. She explains, "‘We have advanced as a species to the point where natural selection no longer removes the outliers in the gene pool.", and that is how natural selection is influencing this microevolution.
