Which two epochs comprise the Quaternary period?

Holocene and Miocene
Pleistocene and Holocene
Eocene and Pliocene
Oligocene and Pleistocene

The correct answer is: Pleistocene and Holocene

The Quaternary period is comprised of two distinct epochs: the Pleistocene and the Holocene. The Pleistocene epoch is significant as it encompasses a series of glacial cycles and represents a time frame when large mammals, such as woolly mammoths and saber-toothed cats, roamed the Earth. Following the Pleistocene, the Holocene epoch began approximately 11,700 years ago and continues to the present day. This epoch is marked by the development of human civilizations and significant climatic changes following the last ice age. Understanding these two epochs is crucial for recognizing the timeline of Earth's geological and biological history. The Pleistocene set the stage for the more stable, warmer climate of the Holocene, during which human populations began to flourish. The other options listed do not correctly reflect the epochs of the Quaternary; they include earlier geological epochs not part of this period, making them incorrect.
