There were significant sex differences only in the Tenerife sample for the maxilla, the incidence in females being higher than in males. In the Gran Canaria sample, the total frequency (male and female combined) of third molar agenesis (individual count method) was 8.7% for the maxilla and 9.3% for the mandible. In the Tenerife and La Gomera samples, the frequencies were 11.1% and 10.7% for the maxilla and 14.6% and 13.3% for the mandible. In the Tenerife sample, the differences between both jaws were statistically significant. The incidence of missing third molars in the mandible was significantly higher in Tenerife than in Gran Canaria, but the other sample differences were statistically nonsignificant. Bilateral absence of third molars was observed in about two\u2010thirds of the specimens examined. Some correlation between both jaws for the occurrence of third molar agenesis was found. The hypotheses that have been proposed in order to explain third molar agenesis in man are discussed. It is suggested that the loss of the third molar in <jats:italic>Homo sapiens<\/jats:italic> could be produced by a heterochronic phenomenon of postdisplacement, as a consequence of the phylogenetic tendency toward the delay of the onset of the third molar formation, and that the genetic factors responsible for the absence of these teeth could be related to the general process of delay in tooth formation.<\/jats:p>","DOI":"10.1002\/ajpa.1330790208","type":"journal-article","created":{"date-parts":[[2006,2,4]],"date-time":"2006-02-04T09:47:47Z","timestamp":1139046467000},"page":"207-215","source":"Crossref","is-referenced-by-count":33,"title":["Third molar agenesis in human prehistoric populations of the Canary Islands"],"prefix":"10.1002","volume":"79","author":[{"given":"Jos\u00e9 Mar\u00eda Berm\u00fadez","family":"De Castro","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,4,27]]},"reference":[{"key":"e_1_2_1_2_1","first-page":"125","article-title":"Excavaciones arqueol\u00f3gicas en la cueva de la Arena (Barranco Hondo, Tenerife)","volume":"22","author":"Acosta P","year":"1976","journal-title":"An.
