Early humans and their ancestors survived by successfully mastering their environments to meet their daily needs. They learned to control fire for cooking food, developed early stone tools, and over time, created increasingly more complex and finely-crafted tools. Recent research suggests that as far back as 165,000 years ago in southern Africa, early humans understood that fire could help them craft more effective tools. Listen to hear a scientist describe the evidence for early human “pyro engineering” and what it tells us about our evolution and development.

Black Women Math Heroes at NASA

Until recently, few people knew that the American space program’s early success was due in large part to a group of African American women known as “human computers.” They were brilliant mathematicians but were made to use segregated offices, bathrooms, and equipment.
