Answer: Learning about the past requires input from multiple sciences.
Explanation:
Archaeology has to be a multidisciplinary comparative science because knowledge from quite a number of sciences are needed to acquire and analyse archaeological finds depending on the needs of the discovery.
Biology for instance is needed to understand the composition and age of discovered organisms. Geology is needed to understand the rock formations to enable archaeological finds. Chemistry is needed to samples collected. And engineering is needed to understand the best technology needed to unearth archaeological finds.
Even social sciences like economics and history are needed so that the archaeologists can give context to what they find. Archaeology truly is a multidisciplinary comparative science.
