From the NY times article on John and Mike MEW:
When I asked her if she’d ever seen an ancient specimen with crooked teeth, she didn’t hesitate: “No, not one. Ever.” Most of the skulls in the Penn collection date from a 40,000-year period starting late in the Stone Age and ending around 300 years ago, yet “they all have an edge-to-edge bite,” “robust” jaws and “perfect” occlusion, Monge said.
But then, in specimens from people who lived two centuries ago or less, Monge noted a striking change: The edge-to-edge bite completely disappears, and malocclusion suddenly runs rampant. She pointed to a skull on a nearby shelf — that of a woman who lived in 19th-century North America. Unlike the ancient skulls, this postindustrial woman’s maxilla was crinkled and small; the teeth that remained sat crammed together. “I always told my students, ‘Something happened 200 years ago and nobody has an edge-to-edge bite anymore — and I have no freaking idea why,’” Monge said.
She took the skull of a preindustrial Siberian man out of her container and clicked the mandible into place. The bone was thick; the teeth met so neatly that they appeared pulled from an Invisalign ad. Monge laughed, her open mouth revealing a pair of missing molars. She cradled the skull in her hand. “Isn’t that just perfect?”
