Final answer:
Organic materials like wood, paper, leather, and straw are generally not prone to long-term preservation in the archaeological record unless specific conditions protect them from the usual decay processes. Archaeological records tend to have more artifacts made from durable materials like stone, marble, and clay. Preservation efforts include controlled storage conditions and, in some instances, the use of chemical treatments.
Step-by-step explanation:
Different materials indeed have varying chances of being preserved in the archaeological record. Organic materials such as wood, paper, leather, and straw are generally not likely to survive over long periods of time unless they are preserved under very specific conditions that prevent decay. For example, wood can survive as fossilized firewood or through tree ring data if it is kept under conditions that prevent the normal processes of degradation, such as in anaerobic environments or due to rapid burial.
Paper has a better chance of preservation if it is protected from moisture and light, such as the papyrus scrolls preserved in the dry heat of Egypt. Leather, often found as remnants of medieval clothing or as weapons used by premodern armies, can survive in dry conditions but is susceptible to decay when exposed to moisture. Straw, much like wood, is biodegradable and less likely to be found unless preserved in a dry, stable environment.
Artifacts such as those made of clay, marble, and stone have a higher chance of surviving over time. The archaeological record relies heavily on artifacts that were made of more durable materials, offering insights into past civilizations. However, biological anthropologists and archaeologists must take great care in the storage and preservation of such materials to prevent further degradation, sometimes using techniques like freezing or chemical stabilization.
