Complete baloney.

Teeth are easily lost, so wisdom teeth are nature's backup plan, or so I heard.
Could be the case.
But the explanation of crowded tooth being ascribed to evolution is completely false. If one dug around literature even a teeny bit one realizes that many hunter gather groups even today have a a full set of tooth perfectly aligned in the jaw. Dentists, Weston A. Price about a century back and more recently John and Mike Mew (father/son so the same last name) come to mind who tell a different story from the mainstream evolutionary explanation for crowded tooth.
