About the Glacial periods of our Earth. Over the past 3 billion years, the Earth has undergone approximately 5 significant ice ages. The first one - Cenozoic Ice Age began 34 million years ago. The latest one - the Quaternary glaciation, which is in progress since 2.5 million years ago. Within the major ice ages there are the periods of severe and mild glacial conditions known as the glacial and inter-glacial periods. The Earth is currently in such an inter-glacial period of the Quaternary glaciation - the Holocene epoch. The most recent glacial period - Quaternary glaciation, have ended between about 120,000 and 11,700 years ago. Interesting facts: The most recent glacial period - Quaternary glaciation, have ended between about 120,000 and 11,700 years ago. Humans developed significantly during the most recent glaciation period, emerging as the dominant ’land animal’ afterward as such large species as the mammoth, giant ground sloths, the mastodons, saber-toothed cats etc. which reigned during the glac
