概括
对骨的形态分析揭示了北克的法国殖民者之间明显的区域多样性. 蒙特利尔的天主教和新教墓地之间的相似之处表明,爱尔兰移民影响了人口结构.
科学领域:
- 生物考古学的生物考古学
- 人类学是人类学.
- 人口遗传学 人口遗传学
背景情况:
- 北克的生物考古学分析受到骨保存不佳的限制.
- 自殖民时期以来,遗传和家谱研究记录了迁徙事件和家庭结构.
- 这项研究利用骨形态学探索圣劳伦斯谷过去的人口结构.
研究的目的:
- 调查法国和英国政权期间圣劳伦斯谷的人口结构.
- 分析骨的形态变异,以了解人口的亲和关系.
- 确定北克历史人口的区域多样性和迁移影响.
主要方法:
- 收集了来自7个人口 (法国天主教和英国新教) 的214个个体的3D几何形状数据.
- 使用Procrustes距离,MANOVA,区分函数分析和Fst估计来测量形态差异和人口亲和力.
- 使用群间分析和Mahalanobis距离探索形状变化.
主要成果:
- 天主教墓地表现出强烈的亲缘关系,但不同的区域形态多样性.
- 蒙特利尔在三个世纪的时间里表现出较低的形态变异.
- 在蒙特利尔的天主教和新教墓地之间没有发现形态差异,这表明潜在的爱尔兰或混合个体.
结论:
- 法国殖民者对后裔人口的贡献各不相同,导致了显著的区域间形态差异.
- 在工业时代开始时,蒙特利尔的新教和天主教人口之间的形态亲缘关系可能表明爱尔兰移民的遗传贡献.

01:27Cranial Bones: Lateral View
2.2K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:22Sutures of the Skull
6.8K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
