The Ice Age was a cold time period where wooly mammoths roamed free, sea levels were at bay, and isthmuses served as a natural means of transportation.
Historically, there have been five major Ice Ages, with the first dating 2.3 billion years ago. During the first Ice Age, a huge layer of ice that was more than 650 feet thick encoated one-third of the Earth. Today, leftover ice still covers Greenland and Antarctica.
The book World History Encyclopedia states, “Since the Quaternary Ice Age, there have been 17 glacial (cold) and 17 interglacial (warm) periods.” Ice Ages start from the Earth changing its direction in its path as it orbits the Sun. The first Ice Age was called the Huronian Glaciation. Right now, we are living in the Holocene, a geological time period that began 11,700 years ago after the most recent major Ice Age.
There is a bridge called the Bering Strait that was caused by the Ice Age. It was caused by falling sea levels which led to a land bridge forming from Asia to North America. Some people say that this was the route taken by early Asian populations into the Americas.
The people coming over the bridge were met by the wooly mammoths.These creatures were a great source of meat for humans, they provided food to feed their families for months, skin to keep people warm in the cold, and bones to make bladed weapons. While wooly mammoths' lives were harsh because people were hunting them, humans had a more difficult life. A lot of people lost their lives mainly due to freezing cold temperatures. While one wooly mammoth could provide food for a family for months, killing a wooly mammoth was a rare and difficult endeavor.
The Ice Age period caused many changes to the Earth’s climate and the creatures and people that lived during the time. Learning about this period allows for a better understanding of how the past shaped the lives we live today and how times have changed.
