Question

The epoch of human civilization is
A. Pliocene
B. Holocene
C. Pleistocene
D. Palaeocene

Answer 1

The epoch is a very long period of time in the evolution of the earth, characterised by particular physical or biological characteristics.

Complete Answer:
The era of human civilization is the holocene epoch as the latest holocene epoch, which began about 12,000 years ago, during which human civilization flourished. There are seven epochs-
1. Paleocene: Approximately 67 million years ago, with substantial radiation from mammals , birds and pollinating insects.
2. Eocene: Approximately 56 million years ago and the predominance of angiosperm and radiation of the most common mammalian ancestor.
3. Oligocene: Approximately 34 million years ago, with a pronounced root in several primate groups.
4. Miocene: Around 23 million years ago, characterised by continuous radiation of mammals and angiosperms and the beginning of the early human ancestor.
5.Pliocene: Approximately 6 million years ago and a marked presence of bipedal human ancestors.
6. Pleistocene: Around 3 million years ago, named the ice age and the root of the Homo genus.
7. The Holocene epoch: On the geological time scale, the Holocene epoch begins at the end of the last glacial era of the current ice age (approx. 10,000 BCE) and continues to the present. The beginning of Mesolithic is generally considered to correspond to the beginning of the Holocene period.

Thus the correct answer is option(B) Holocene.

Note: The categorization of the past into discreet, quantified time blocks is called periodization. Significant categorization structures include cosmological (time periods in the origin and mass evolution of the universe), geological (time periods in the origin and evolution of the Earth), anthropological and historical (time periods in the origin and evolution of human civilisation).
