The Probability of Life Appearing in the Universe
10:26 - 19:53 (09:27)
Astrophysicist Adam Frank explains the probability of life appearing in the universe on a planet like Earth in proportion to the time that it's been ready for life to appear, and how each step in the process was hard.

Summary
Earth has been fortunate to achieve all the intermediate steps of evolution that led to advanced life within a short time. Each step of evolution involved complex processes such as multicellular animals, photosynthesis, and sexual selection over a span of five billion years.

A statistical model predicts the probability of completing life's hard steps, which are difficult to find and unlikely, within a finite window.
13:29 - 16:50 (03:20)
Summary
A statistical model predicts the probability of completing life's hard steps, which are difficult to find and unlikely, within a finite window. These steps could be of varying difficulties, and the model estimates the solution or passing of them.
