Pigs are the unlikely model for this latest research into regenerating human teeth. Image source: agnormark/Adobe. In a recent study, Yelick and her team successfully grew human-like teeth in pigs.

The pig’s mouth revealed its ordinary sharp, tusk-like canines saddled up beside smaller, slightly more human-looking teeth nubs. In theory, a similar process could play out in humans.

Two-million-year-old teeth transform theory of prehistoric human evolution. Changes in the appearance of ancient teeth could act as a new evolutionary marker, writes Ian Towle.
