Final answer:
The first technology at the Dillard site were stone tools akin to Oldowan tools, used for various activities including hunting and food preparation, marking a significant advancement in human technological history.
Step-by-step explanation:
The first technology or tool created by people at the Dillard site, as suggested by the video and historical records, would be stone tools similar to the Oldowan tools. These represent the earliest known stone tool industry, dating approximately from 2.5 million to 1.5 million years ago, and were possibly crafted by either Homo habilis, Paranthropus boisei, or both. Oldowan tools were created using hard hammer percussion, resulting in a core from which flakes were chipped off, used for activities such as killing game, cutting meat and plants, and potentially woodworking. This stage of stone tool development signified a significant milestone in human evolutionary history and technological advancement.
