Episode notes
Early Bone Tool Use
- Early humans used stone tools long before Homo sapiens, exemplified by hand axes from the Acheulean period.
- A new study reveals bone tool use in Eastern Africa 1.5 million years ago, pushing back the timeline significantly.
Cognitive Advancements
- Bone tools suggest early humans used mental imaging to create tools, replicating mental images with their hands.
- This indicates advancements in cognition as they applied stone tool knowledge to new materials like bone.
E-taste: Tasting Lemonade Virtually
- Researchers developed "e-taste," a device simulating tastes in virtual reality by analyzing chemical compositions.
- It replicates simple flavors, like lemonade from across the country, by sending data and recreating it with chemicals.
