Stone tools serve as evidence for human evolution; increasingly complex and adapted tools suggest developing brain sizes and capabilities in ancestral Homo species.
Como as ferramentas de pedra podem ser usadas como evidência da evolução humana? Ferramentas mais antigas usadas por espécies de Homo mais antigas são menos complexas. À medida que começaram a evoluir, as ferramentas ficaram mais afiadas e mais adaptadas aos seus usos, o que sugere que seus cérebros ficaram maiores.

| Back | Older tools used by older Homo species are less complex. As they started to evolve, the tools got sharper and more adapted to their uses which suggests their brains got larger. |
