Geologic time scale (GTS), a system of chronological dating used to show events that have occurred in Earth’s history
Table of Contents
All time before life existed, Earth was still a volatile environment, though the origins of life came around during this period.

• First Life on Earth
• Cell Development & Diversification
The development of multi-cellular organisms, including sponges, primitive animals, and various plant life, diversifying from old species
• Multicellular Organisms
• Primitive Animals
The transition from primitive species to specialized organisms, the increasing of genetic diversity via sex, and the transition from sea to land
• Arthropods

• Fish
The arrival and dominance of dinosaurs in the air, land, and sea, and how they developed from their ancestors and the causalities of their existence
