Explore the prevailing scientific theory of why crooked teeth and impacted wisdom teeth are recent developments in human evolution.

--

According to the fossil record, ancient humans usually had straight teeth, complete with wisdom teeth. In fact, the dental dilemmas that fuel the demand for braces and wisdom teeth extractions today appear to be recent developments. So, what happened? While it’s nearly impossible to know for sure, scientists have a hypothesis. G. Richard Scott shares the prevailing theory on crooked teeth.

Lesson by G. Richard Scott, directed by Igor Coric, Artrake Studio.
