The sun appears to set in the west each day.As such, zircons can literally tell the entire history of the planet — if you know the right questions to ask. The scientists sought to determine the oxidation levels of the magmas that formed these ancient zircons to quantify, for the first time ever, how oxidized were the gases being released early in Earth's history.Earth's history with time-spans of the eons to scale. The history of Earth concerns the development of planet Earth from its formation to the present day. Nearly all branches of natural science have contributed to understanding of the main events of Earth's past, characterized by constant geological change and biological evolution.
