EARLY PLEISTOCENE Meaning and
Definition
-
The Early Pleistocene is a geological epoch that is a subdivision of the larger Pleistocene epoch. It is characterized by a specific period of time that occurred approximately 2.6 million to 780,000 years ago, following the Pliocene epoch and preceding the Middle Pleistocene.
During the Early Pleistocene, the Earth experienced significant climatic and environmental changes. The epoch is known for the onset of glacial-interglacial cycles, with repeated occurrences of ice ages and warmer interglacial periods. These fluctuations had a profound impact on the Earth's ecosystems, leading to the development of new species and the extinction of others.
It is in the Early Pleistocene that early humans, belonging to the Homo genus, began to emerge and diversify. Notable species include Homo habilis and Homo erectus, who displayed advancements in toolmaking and other cultural behaviors.
Geologically, the Early Pleistocene is marked by the deposition of sedimentary layers, which provide valuable information about past climates, sea levels, and the evolution of life forms. Fossils of various organisms, such as mammals, birds, and plants, are found within these layers, helping scientists piece together the evolutionary history of the Pleistocene period.
Overall, the Early Pleistocene represents an important period in Earth's history, characterized by dynamic environmental changes and the emergence of early human ancestors. It holds significant scientific value in understanding the Earth's past and its impact on shaping life as we know it today.
Etymology of EARLY PLEISTOCENE
The etymology of the word "early Pleistocene" can be broken down as follows:
1. Early: The word "early" comes from the Old English word "earlic" which means "occurring near the beginning" or "in the first part of a period". It is derived from the Old English word "ear" meaning "soon". Over time, the spelling and pronunciation evolved to "early", which has remained unchanged in modern English.
2. Pleistocene: The word "Pleistocene" is made up of two elements: "Pleisto-" and "-cene".
- "Pleisto-" comes from the Greek word "pleistos" meaning "most" or "very". It is derived from the Greek word "pleion" meaning "more" or "greater".
