N1 - Funding Information:
Funding for this study comes from the Spanish Ministry of Science/FEDER, grant numbers CGL2012-38434-C03-01/02/03, CGL2014-52611-C2-1-P, CGL2015-65387-C3-2-P, CGL2015-65387-C3-3-P, PGC2018-093925-B-C31, HAR2014-55131, HAR2017-86509-P), the Generalitat de Catalunya (2014 SGR 900, 2014/100574, 2014/100482, AGAUR projects 2014SGR-108 and 2017 SGR 11), Acción Integrada Francia-España (HF2001-0115), Consejería de Educación de la Junta de Castilla y León (CEN074A12-2), The Leakey Foundation (through the personal support of Gordon Getty 2013 and Dub Crook 2014, 2015, 2016, 2018 to one of the authors MM-T). MMP and LMF are beneficiary of postdoctoral grants by the Atapuerca Foundation and IdEx, respectively. CG-C, MM-M and MMP were funded by a doctoral grant from the European Social Funds (BOCYL-D-02102014-10 and BOCYL-D-20052013-14) through the Consejería de Educación de Castilla y León (Spain) with European Social Funds. Most of the data acquisition was performed at the Laboratory of Microscopy of the CENIEH-ICTS (Spain) in collaboration with CENIEH staff. Restoration and conservation works on the material have been carried out by Pilar Fernández-Colón from the Conservation and Restoration Area of CENIEH-ICTS, Lucía López-Polín from IPHES and Maicu Ortega from the Centro de Evolución y Comportamiento Humanos UCM-ISCIII. Isidoro Campaña and Jordi Rosell helped us in interpreting the position of the Gran Dolina fossils in the stratigraphy of the Gran Dolina-TD6 unit. Marina Lozano, Ignacio Martínez, Cáceres Museum and Extremadura Government helped in accessing the scientific material. Without the persistent effort of the Atapuerca Research Team, Primeros Pobladores de Extremadura, Cova dels Galls Carboners and Cova de la Guineu teams and excavators, this work would have not been possible. We are especially grateful to the referees and Associated Editor for their comments and suggestions, which have greatly improved the paper.

N2 - Characterizing dental development in fossil hominins is important for distinguishing between them and for establishing where and when the slow overall growth and development of modern humans appeared. Dental development of australopiths and early Homo was faster than modern humans. The Atapuerca fossils (Spain) fill a barely known gap in human evolution, spanning ~1.2 to ~0.4 million years (Ma), during which H. sapiens and Neandertal dental growth characteristics may have developed. We report here perikymata counts, perikymata distributions and periodicities of all teeth belonging to the TE9 level of Sima del Elefante, level TD6.2 of Gran Dolina (H. antecessor) and Sima de los Huesos. We found some components of dental growth in the Atapuerca fossils resembled more recent H. sapiens. Mosaic evolution of perikymata counts and distribution generate three distinct clusters: H. antecessor, Sima de los Huesos and H. sapiens.
