Question
Chapter 13, Problem 1WIO
Summary Introduction
To determine:
The significance of geologic timescale with reference to evolution.
Introduction:
Life began on earth about 3.6 billion years ago. Fossil records are used to determine the type and age of an organism that existed in the early period of Earth’s history. The study of the fossil record is called paleontology.

Example: The boundary between the Precambrian eon and the Phanerozoic eon is marked by the rapid evolution and diversification of organisms with hard body parts. The time intervals are eons, which are subdivided into eras. The eras are subdivided into periods. The periods are further subdivided into epochs (not shown on figure).
