Schultz's rule

Schultz's rule is a rule developed by Adolph Hans Schultz, ^[1] declaring a relationship between the first tooth eruption of the molar versus the permanent teeth and the progress or aging of its carrier. ^[2] It states that species that live longer have more wear on deciduous teeth and as a result start replacing them relatively early in life. Which is an indicator for examining fossil data. According to research, Myotragus balearicus follows Schultz's Rule. ^[3]
