Archeologists have long searched sites across Central America to learn about the ancient civilizations that once thrived there. One of those civilizations is the Olmecs, an early Central American people, whose culture pre-dates the Mayans. In this audio story you will hear about the discovery of a stone block that seems to date back to the Olmecs, over 3,000 years ago. It contains what might be the oldest writing ever found in the Americas. Listen to learn more about the significance of this discovery.

Most scientists agree that human beings originated in Africa. The first humans to come to North and South America has long been believed to be the Clovis people. But a 2002 discovery in the Paisley Caves in Oregon has challenged this view. Archaeologists discovered animal bones and fossilized excrement, known as coprolites. Some of these coprolites included human molecules, providing the earliest human DNA ever found in the Americas. This discovery has given archaeologists new clues to better understand the earliest humans found in North America.
The earliest known fossil that lead to humans was recently discovered in Ethiopia. Scientists have uncovered a lower jaw with five teeth. The jaw is estimated at about 2.8 million years old, and is nearly half a million years older than the previous record for a human-related fossil. This bone could help explain a branch in the human family tree. Listen to the story to find out how this fossil could fill a gap in the history of human evolution.
The people of Ancient Mesopotamia practiced mathematics from the early days of Sumer to the fall of Babylon in the 6th century. Until recently, most evidence suggested that math was used primarily for things like measuring land. A new discovery by a researcher in Berlin has shed new light on how Babylonians used geometry to measure the changes in the velocity of Jupiter over time as it moves across the sky. Prior to this discovery, the use of geometry in this manner was thought to have come in the middle ages. Listen to hear how this new discovery shows that Babylonian mathematics was more sophisticated than previously thought.
At its height, the Persian Empire stood as one of the ancient world’s largest and most powerful empires. One of its most famous leaders was the king known as Cyrus the Great who ruled Iran from 550-530 BC. One of the Persian Empire’s great treasures is the Cyrus Cylinder, which tells the story of Cyrus The Great’s rule. The cylinder depicts Cyrus as a king who was seen both as a great political and military leader, as well as the ancient world’s equivalent of a humanitarian. Evidence for all of these characteristics can be found on the Cyrus Cylinder. The audio story describes the cylinder as one of the oldest declarations of human rights found in archaeology. It also describes the pride modern Iran, often criticized for human rights violations, has for the legacy of Cyrus the Great.
