Chapter 25, Problem 1ITD
Summary Introduction
To review:
Whether the decline in the asteroid impact or the rise in atmospheric levels of oxygen took place first.
Introduction:
Earth was formed around 4.6 billion years ago. The first life form evolved around 3 billion years ago. It was a primitive life form and continued like that for around 2 billion years. The humans first evolved around 315,000 years ago.

Scientist have determined that the early Earth had no free oxygen anywhere. Briefly explain what evidence in
the rock layers that scientists found to prove when the early conditions on earth had free oxygen in the
atmosphere.
The Miller-Urey experiment simulated compounds present in the atmosphere of early Earth, lightning, and the evaporation and condensation of atmospheric water. What other information about the conditions on Earth during this time period would you want to know to improve the experiment
