Dissertation Research: A Cross-Sectional Study of Dental Development in Chimpanzees of Known Age and Sex

早期原始人类牙齿发育的速度和模式 当前物理学研究中的争议焦点 人类学 这一争议是更大问题的一部分， 早期原始人类的发育期是否 其特征是更“像人类”、更“像猿”或不同 两者都没有 延长的发育期特征 现代人的行为在很多场景中都被强调 关于人类各种物质、文化和 行为特征 然而，最近的研究表明， 与现代猿类相当。 如果是这样的话， 大脑、工具使用和社会组织都会受到影响。 人类牙齿发育的速度是众所周知的，但现有的 猿类牙齿发育的标准是不够的， 样本量很小，它们不是来自已知的个体， 实际年龄，以及前部的放射学信息 缺牙。 本研究的目的是记录模式和时间 乳牙和恒牙牙冠和牙根的形成 已知年龄和性别的黑猩猩的横截面样本 为了提供基线数据与人类进行比较， 原始人类化石样本

The rate and pattern ofdental development in early hominids is a focus of controversy in current research in physical anthropology. This controversy is part of the larger question of whether developmental periods in early hominids can be characterized as more "humanlike", more "apelike", or distinct from either. The prolonged developmental periods characteristic of modern humans have been emphasized in many scenarios concerning the origin of various human physical, cultural, and behavioral traits. However, recent research suggests that early than modern humans, comparable to that of modern apes. If so, brains, tool use, and social organization, will be affected. Rates of human dental development are well known, but existing standards of ape dental development are inadequate since the sample size is small, they are not from individuals of known chronological age, and radiographic information on the anterior dentition is lacking. The objective of this study is to document the pattern and timing of deciduous and permanent tooth crown and root formation in a cross-sectional sample of living chimpanzees of known age and sex in order to provide baseline data for comparison with human and fossil hominid samples.
