A colossal asteroid impact approximately 66 million years ago brought an end to the reign of the dinosaurs and reshaped life on Earth. The asteroid, estimated to be about 10–15 kilometers wide, struck the Yucatán Peninsula in present-day Mexico, creating the Chicxulub crater. The impact released energy equivalent to billions of nuclear bombs, triggering massive wildfires, tsunamis, and a "nuclear winter" effect. Dust and debris blocked sunlight for months or even years, leading to the collapse of food chains.
While many species perished, some life forms—especially small mammals, birds, and reptiles—managed to survive and adapt to the changed environment. This mass extinction event allowed mammals to rise as the dominant land animals, eventually leading to the evolution of primates and, ultimately, humans. The Cretaceous-Paleogene extinction was a turning point in Earth's history, demonstrating how sudden, catastrophic events can alter the course of evolution forever.
