What are the origins of life? How did things go from non-living to living? From something that could not reproduce to something that could? Earth is estimated to be about 4.5 billion years old, and for much of that history it has been home to life in one form or another. Our planet is teaming with life, from the highest mountain to the deepest ocean; life is everywhere. But what was the firing pistol that started the evolutionary race? How did material go from non-living to alive? It's one of the most fundamental and difficult questions that has challenged us since the beginning of time.

We have an expectation that science is calculated and controlled. Yet some of the most influential scientific discoveries have been made entirely by accident. Does chance work alone or are other phenomenons at play? Combining dramatic re-creation with cheeky animation and cleverly manipulated archival images, Gone Sideways illustrates three areas of exploration: medicine, technology and natural science.
