The Pleistocene epoch is a geological time period that began about 2.6 million years ago and ended around 11,700 years ago. It is often referred to as the Ice Age because of the repeated glaciations that occurred during this time.
During the Pleistocene, the Earth experienced several glacial and interglacial periods. The climate fluctuated between cold glacial periods, when ice sheets covered large parts of the planet, and warmer interglacial periods, when the ice retreated. These climatic changes had a profound impact on the environment, shaping the landscapes and influencing the evolution of various species.
The Pleistocene epoch was a time of significant biological evolution. Many species adapted to the changing climate, and some became extinct. Mammals such as mammoths, mastodons, sabertooth cats, and giant ground sloths roamed the Earth during this time. Early humans, known as Homo erectus and later Homo sapiens, also emerged and thrived in various parts of the world.
Study Tips
To understand the Pleistocene epoch better, consider the following study tips:
Use models to describe that energy in animals’ food (used for body repair, growth, motion, and to maintain body warmth) was once energy from the sun.
