Question 44

Two different stone tools discovered in different archaeological sediment layers. Tool X is a primitive stone tool from 1.5 million years ago, showing minimal flaking with large, coarse chips removed to form a basic, uneven scraping edge. Tool Y is a sophisticated flint tool from 40,000 years ago, showing highly refined, delicate pressure-flaking along both sides to create a thin, symmetrical, and sharp spearhead.

Explain how the differences between Tool X and Tool Y provide evidence for human evolution.
