Final answer:
Males typically have larger muscle attachment marks on their bones and a larger rib cage and shoulders than females, due to the growth patterns during puberty and the anatomical adaptations for reproduction in females.
Step-by-step explanation:
In biological terms, it is males who generally have larger muscle attachment marks on their bones and a larger rib cage and shoulders compared to females. This is due to the differences in growth patterns and hormone influences during puberty, where males experience a significant increase in muscle and bone growth, particularly in the upper body. The broadening of the shoulders and chest in males, as opposed to the widening of the hips in females, is a clear example of sexual dimorphism, which refers to the differences between sexes of the same species that aren't directly involved in reproduction. The male pelvis is narrower and features a deeper sciatic notch, whereas the female pelvis is adapted for childbirth and is therefore wider, with a broader subpubic angle. Due to these anatomical differences, the skeletal structure of males typically supports larger muscle attachment and a more pronounced upper body build.
