Quaternary is the geologic time period that began 2.6 million years ago and continues to the present day. It is the most recent period of the Cenozoic Era and is characterized by the emergence of modern humans and the development of agriculture.
Quaternary is a term used to describe the most recent period of geologic time, which began approximately 2.6 million years ago and continues to the present day. It is the fourth and final period of the Cenozoic Era, which is the current era of geologic time. The Quaternary Period is characterized by the emergence of modern humans, the development of agriculture, and the rise of civilizations.
The Quaternary Period is divided into two epochs: the Pleistocene and the Holocene. The Pleistocene Epoch began approximately 2.6 million years ago and ended 11,700 years ago. During this time, the Earth experienced a series of glacial and interglacial cycles, which caused the climate to fluctuate between cold and warm periods. This period is also known as the Ice Age, and it is during this time that modern humans first appeared.
The Holocene Epoch began 11,700 years ago and continues to the present day. During this time, the climate has been relatively stable, and human populations have grown and developed. This period is marked by the development of agriculture, the rise of civilizations, and the emergence of modern technology.
The Quaternary Period is characterized by a number of significant changes in the Earth’s climate, environment, and human populations. These changes have had a profound impact on the planet and its inhabitants, and they continue to shape the world we live in today.
