The guest on this episode answers the question: Why do we tend to have so many issues with our teeth and jaws? How many of us have had teeth pulled, such as our wisdom teeth, and have had braces that align our crooked teeth? If we look at other mammals, we don't see these issues at all. We can even look to our closest relatives, the chimp and the bonobo, and we see that there are very few issues that arise in the development of their teeth and jaws.
