Abstract

In this research we studied the number of perikymata and the distribution of perikymata in all teeth, the periodicity between Retzius striae and and relative dental development using the Bayes theorem of the Atapuerca hominins (Burgos, Spain). Specifically, we studied the Sima del Elefante hominin (~1.2 Ma), H. antecessor of Gran Dolina-TD6 (~0.86 Ma) and the Sima de los Huesos hominins (~0.46 Ma). Our data indicate that the dental development of the Atapuerca hominins was faster than that of modern humans. However, no differences were found in the average lateral enamel formation times between Sima de los Huesos and Neandertals, despite their molars present variation in the perikymata counts. A mosaic evolutionary pattern has been observed in the dental development.
