Some skeletal traits that define modren homosapiens are a small face, high rounded skull, small jaws, bony chin , vertical and h
igh forehead, a narrow nasal aperture, narrow upper body and long legs. Regional variability plays a role in defining skeletal traits because of environmental influences which pressure bone growth, which means that skeletal traits appear according to the pressures of the environment.
Some skeletal traits that define modern homo sapiens are a small face, high rounded skull, small jaws, bony chin , vertical and high forehead, a narrow nasal aperture, narrow upper body and long legs is known as mental eminence.
<h3>What are skeletal traits?</h3>
The morphological diversity of the domestic dog serves as an example of how mammalian skeletal traits may evolve quickly and undergo significant modifications.
Here, we employ principal component analysis to identify systems of features characterizing skeletal traits in a population of Portuguese Water Dogs.
Through this research, phenotypic variation is divided into separate parts that can be utilized to analyze the genetic networks controlling intricate skeletal traits.
We demonstrate that unlinked quantitative trait loci associated with these major components separately support both inverse correlations between structures and correlations within skeletal traits (for example, within the skull or among the bones of the limbs) (e.g., skull vs. limb bones).

I suggest you to provide some options, as it's quite difficult to answer your question. Here is your answer: A long bone is covered externally with a sheath called the periosteum, whereas the marrow cavity is lined with the <span>endosteum</span>. I've attached the illustration to make it clear for you
