Answer:
The first great leap for humans was stone weapons
Step-by-step explanation:
From history, we understand that at some points in human development, the early humans made a relatively wide variety of stone tools that were used for processing various plant and animal materials.
The earliest known human-made stone tools date back around 2.6 million years ago.
These stone tools and other artifacts gave evidence on how things were made by the early, the way they they lived and how they interacted with their surroundings
Common items in their tool kits include (but not limited to) choppers, cleavers, and hammers as well as flakes used as knives and scrapers.
