Labels:text | screenshot | font OCR: QUATERNARY PERIOD 2 MYA-TODAY The Quaternary Period is often called the "Great Ice Age." Northern lands became so cold that ice from the Arctic regions spread far to the south of them. Some 10,000 years ago, the last ice age gave way to a much warmer period, known as the Holocene or Recent Epoch. During this time, humans evolved to become the dominant species.
