The Neogene: A Time of Big Changes!

The Neogene was a super long time in Earth's past, lasting for about 20 million years! It happened after the Paleogene period and before the Quaternary period, which is the one we live in now. Think of it like a giant chapter in Earth's storybook, filled with exciting new creatures and big adventures for our planet. It’s when many of the animals we know today started to appear!

This incredible time started about 23 million years ago and ended about 2.5 million years ago. That's so long ago, it's hard to even imagine! It was divided into two parts: the Miocene and the Pliocene. During these times, the world looked very different. Continents were still moving around, and the climate was changing, which made life exciting for the animals living then.

During the Neogene, mammals and birds really started to change and become more like the ones we see today. Some of the earliest humans, called Homo habilis, even showed up near the end of this period! Imagine giant rhinos, early horses, and saber-toothed cats. It was a time of incredible animal evolution, with many new species popping up and old ones changing.

One of the most amazing things that happened during the Neogene was when North and South America joined together with a new land bridge called the Isthmus of Panama. This changed ocean currents, like a giant water slide for heat! The whole planet also started to get cooler, which eventually led to the ice ages in the next period. It shows how much our Earth is always changing.
