项目摘要

A research database of digital images and skeletal measurements of ancient Japanese dogs and recent dog breeds was constructed by Shigehara. The main part of the ancient dog sample is stored in The University Museum, The Tokyo University, of which specimens were collected by Dr.Kotondo Hasebe. We are in the process of checking a trial version to open the database in a research web site. Ancient dog materials from archaeological sites allover Japan were additionally included to the sample.DNA taken from archaeological Japanese dog materials, Recent Japanese dog breeds, and archaeological Chinese dog materials were analyzed by Ishiguro. This genetic analysis aimed to solve phylogenetic relationships among Japanese dogs. The Chinese dogs fell in M2 O type and M2 type of the genetic classification by Ishiguro. The M2 type represents the basal genetic condition for the ancient Japanese dogs, while the M2 O type is possessed by Japanese dogs introduced in Yayoi period and the later dogs. The … More se results indicated that the traditional Japanese dogs originated in China in archeologically old ages. These inferences from the analysis of archaeological dogs will affect hypotheses on the migration of the basal population of Japanese people.Appearance frequencies of cranial anatomical features among various dog populations and breeds were compared by Komiya and Egi using a non-parametric method. The main part of sample for this analysis consisted of Japanese and Chinese dogs that were collected by Komiya during previous projects, and data of European breeds and wild wolf were additionally collected by Komiya at Natural History Museum in Berne, Swiss. Additionally, morphological variation in the presphenoid and adjacent areas among dog breeds was evaluated. The results of these analyses of relative distances among dog populations indicated that domestic dog breeds can be divided roughly into two groups and that all of the ancient and modern Japanese dog populations make a cluster within one of the group, suggesting a close kinship among Japanese dog populations in relationships of domestic dogs in the world.

Shighara建造了数字图像和骨骼测量的研究数据库。古狗样本的主要部分存储在东京大学的大学博物馆中，其中Kotondo Hasebe博士收集了标本。我们正在检查试用版本以在研究网站中打开数据库。样品还包括了来自考古遗址的古老狗材料。这种旨在解决日本狗的系统发育关系的遗传分析。中国狗以Ishiguro的M2 O类型和M2类型的遗传分类掉落。 M2类型代表了古代日本犬的基本遗传状况，而M2 O类型是由Yayoi时期引入的日本狗和后来的狗所假定的。 …更多的SE结果表明，传统的日本狗起源于中国以考古古老的年龄。根据考古犬分析的这些推论将影响日本人基本人群迁移的假设。使用非参数方法比较了Komiya和Egi的各种狗种群和品种的颅骨解剖学特征的表现频率。该分析样本的主要部分是由科米亚（Komiya）在先前项目中收集的日本和中国狗，而欧洲品种和野狼的数据还由科米亚（Komiya）在瑞士伯尔尼（Berne）的自然历史博物馆收集。另外，评估了狗品种中型前和相邻区域的形态变化。这些对狗种群相对距离的分析的结果表明，家庭狗品种可以大致分为两组，并且所有古老和现代的日本狗种群都会在其中一个人群中群群，这表明日本狗种群之间在全球家养狗关系中的亲属关系很亲密。较少的
