If Bones Don't Decay the Way Flesh Does, Why Don't We See Skeletons Everywhere?
Unlike flesh, which rapidly decomposes, bones endure for extended periods due to their unique composition and environmental conditions. Here's why:
Bone Durability: Bones are primarily composed of collagen and calcium hydroxyapatite, giving them incredible strength and rigidity. This structure makes bones highly resistant to decay.
Collagen Matrix: Collagen fibers form a dense network within bone tissue, providing structural integrity and preventing bacteria from penetrating and breaking down the bone.
Mineralization: Bones are heavily mineralized with calcium and phosphorus ions, which create a hard, protective layer that further strengthens and shields them from decay.
Burial Environment: Most bones are buried underground, where they are protected from exposure to oxygen and moisture. These conditions slow down the decomposition process significantly.
Exceptions: In certain circumstances, bones may indeed decay or deteriorate. For example, exposure to acidic environments (e.g., swamps) or scavenging animals can accelerate bone degradation. However, the vast majority of bones remain intact over long periods.
