The Cretaceous-Tertiary extinction event, or the K-T event, is the name given to the die-off of the dinosaurs that took place some 65.5 million years ago. For many years, paleontologists believed this event was caused by climate change that interrupted the dinosaurs’ food supply, but later, scientists discovered iridium, suggesting a comet, asteroid or meteor impact event may have caused the mass extinction.

Our human ancestors may have lost 98.7 percent of their population around 900,000 to 800,000 years ago, according to genetic research.

The Stone Age

The Stone Age marks a period of prehistory in which humans used primitive stone tools. Lasting roughly 2.5 million years, the Stone Age ended around 5,000 years ago when humans began working with metal and making tools and weapons from bronze.

The Neolithic Revolution, also called the Agricultural Revolution, marked the transition in human history from small, nomadic bands of hunter-gatherers to larger, agricultural settlements and early civilization. It started around 10,000 B.C.

Hunter Gatherers

Hunter-gatherers were prehistoric nomadic groups that harnessed the use of fire, developed intricate knowledge of plant life and refined technology for hunting and domestic purposes as they spread from Africa to Asia, Europe and beyond. 

The Iron Age

The Iron Age was a period in human history that started between 1200 B.C. and 600 B.C. During the Iron Age, people across much of Europe, Asia and parts of Africa began making tools and weapons from iron and steel.

HISTORY: The Bronze Age

The Bronze Age marked the first time humans started to work with metal. Bronze tools and weapons soon replaced earlier stone versions. Ancient Sumerians in the Middle East may have been the first people to enter the Bronze Age.
