Document Summary

At one point there was no life on this planet- (q on exam)- 4. 6 billion years ago the earth began. 15 billion years ago is the age of our universe. 10 billion after that our solar system began. For life to begin on this planet the earth had to cool down and rocks were formed. Then we think shortly after that life began on this planet. That is a hypothesis we will talk about today. For the exam know the difference between scientific hypothesis and theory. The origin of life is not a theory it is a hypothesis. There are many hypotheses about life beginning on earth, but truly we do not know. Some experiments try to replicate the beginning of life. Later we will talk about the theory of natural selection. Miller and urey made this in the 1950s. In this experiment they used simple gases available in the atmosphere 4-4. 2 billion years ago.
