| 摘 要： | 犬齿窝是包括现代人类在内的许多人族成员面部骨骼的重要性状,但在分类学上的意义仍存在争议。有学者认为该性状是一个发生于基础面形的近祖性状,除了一些例外,在灭绝和现生的大猿及人属中都存在。另有学者认为,犬齿窝是仅存在于智人及其直系祖先的衍生性状,在发育上与颧齿槽突嵴有关。这种关系并非总是成立,在智人中存在着明显的差异：弧型颧齿槽突嵴和直斜型颧齿槽突嵴与犬齿窝有时共存,有时不共存。我们由此推测,犬齿窝的发生和形态与上颌窦的前部发育有关,颧齿槽突嵴的形态与鼻窦的侧面发育有关。在人类演化的过程中,犬齿窝经历了不同的变形,比如上颌沟(如南方古猿非洲种、傍人粗壮种)、上颌小窝(如傍人粗壮种)、上颌沟(如匠人)或犬齿窝缺如(如傍人埃塞俄比亚种、傍人鲍氏种、肯尼亚扁脸人、人属鲁道夫种)。犬齿窝消失的原因各类群并不相同,如中新世和早更新世人属以及中更新世人属(如人属海德堡种/人属罗得西亚种、人属尼安德特种)。人属罗得西亚种具有弱化的犬齿窝,不具备演化为智人的可能,因此被排除在智人的演化支之外。

| Abstract: | The canine fossa is an important feature in the facial skeleton of many hominins, including modern humans. However, its phylogenetic significance is debated. Some researchers consider it as a plesiomorphic characteristic in a generalized face that, with some exceptions, is found in both extinct and extant great apes and in the hominins. Others consider that the canine fossa is a derived characteristic only found in Homo sapiens and its direct ancestors, and that it is related to an arched zygomatic-alveolar crest (ZAC). However, this relationship is not always fulfilled, and in Homo sapiens, there is a notable variability: An arched ZAC with the presence or absence of a canine fossa, and straight oblique ZAC with presence or absence of a canine fossa. In this sense, we hypothesize that the canine fossa is related to the degree of anterior extension of the maxillary sinus and that the morphology of the ZAC is related to the degree of lateral extension of said sinus. During the hominine evolution, the canine fossa has undergone different transformations, such as the maxillary furrow (Australopithecus africanus, Paranthropus robustus), maxillary fossula (P. robustus), and the sulcus maxillaris (Homo ergaster), or has been obliterated (Paranthropus aethiopicus, Paranthropus boisei, Kenyanthropus platyops, Homo rudolfensis). In the taxa where it has been obliterated, the mechanism of obliteration is different in the hominins of the Pliocene and Early Pleistocene compared to those of the Middle Pleistocene (Homo heidelbergensis/rhodesiensis, Homo nenaderthalensis). The facial morphology of H. rhodesiensis would exclude it from the line evolving to H. sapiens. |
