First, we employ, for the first time, methods of computational anatomy to model complex symphyseal shape differences. Second, we present new fossil evidence from Kromdraai to improve our knowledge of symphyseal morphology. We describe differences between shapes by landmark-free diffeomorphism needed to align them. We assess which features of the mandibular symphysis best discriminate the juvenile symphysis in these fossil species, relative to the intraspecific variation observed among modern humans. Our approach eliminates potential methodological inconsistencies with traditional approaches (i.e., the need for homologous anatomical landmarks, assumption of linearity). By enabling detailed comparisons of complex shapes in juvenile mandibles, our proposed approach offers new perspectives for more detailed comparisons among\n                    <jats:italic>Australopithecus<\/jats:italic>\n                    ,\n                    <jats:italic>Paranthropus<\/jats:italic>\n                    and early\n                    <jats:italic>Homo<\/jats:italic>\n                    .\n                  <\/jats:p>","DOI":"10.1163\/14219980-bja10014","type":"journal-article","created":{"date-parts":[[2023,8,1]],"date-time":"2023-08-01T00:29:14Z","timestamp":1690849754000},"page":"225-247","source":"Crossref","is-referenced-by-count":6,"title":["Revisiting mandibular symphyseal shape in juvenile early hominins and modern humans using a deformation-based approach"],"prefix":"10.1163","volume":"94","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5093-5854","authenticated-orcid":true,"given":"Veronika A.","family":"Zimmer","sequence":"first","affiliation":[{"name":"School of Computation, Information and Technology, https:\/\/dx.doi.org\/9184Technical University of Munich, Boltzmannstra\u00dfe 3, 85748 Garching, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5665-6581","authenticated-orcid":true,"given":"Anna","family":"Oettl\u00e9","sequence":"additional","affiliation":[{"name":"Sefako Makgatho Health Sciences University, Pretoria, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8206-3966","authenticated-orcid":true,"given":"Jakobus","family":"Hoffmann","sequence":"additional","affiliation":[{"name":"South African Nuclear Energy Corporation (Necsa), Pretoria, 001, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6884-382X","authenticated-orcid":true,"given":"John Francis","family":"Thackeray","sequence":"additional","affiliation":[{"name":"Evolutionary Studies Institute, University of the Witwatersrand, PO WITS, Johannesburg, 2050, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4251-884X","authenticated-orcid":true,"given":"Bernhard","family":"Zipfel","sequence":"additional","affiliation":[{"name":"Evolutionary Studies Institute, University of the Witwatersrand, PO WITS, Johannesburg, 2050, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8483-076X","authenticated-orcid":true,"given":"Jos\u00e9","family":"Braga","sequence":"additional","affiliation":[{"name":"Evolutionary Studies Institute, University of the Witwatersrand, PO WITS, Johannesburg, 2050, South Africa"},{"name":"Centre d\u2019Anthropobiologie et de G\u00e9nomique de Toulouse, Universit\u00e9 Paul Sabatier Toulouse III, Facult\u00e9 de M\u00e9decine Purpan, 37 All\u00e9es Jules Guesde, 31000 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"374","reference":[{"issue":"7109","key":"R000001","series-title":"Nature","first-page":"296","article-title":"A juvenile early hominin skeleton from Dikika, Ethiopia","volume":"443","author":"Alemseged\u00a0Z","unstructured":"Alemseged\u00a0Z, Spoor\u00a0F, Kimbel\u00a0WH, et al.
