From The Guardian:
One of the many things that I appreciate about Richard Dawkins is the overall scientific quality of his speculations: he is an interesting thinker as well as an imaginative one.(via RichardDawkins.net)
In this video we see him conversing with journalist and writer Matt Ridley. Dawkins speculates what is and is not universal about life: life on Earth, life in space, human life, artificial life, synthetic life, the origin of life, the secret of life, the meaning of life.
This discussion is focused on the central question; if/when we discover extraterrestrial life, what might it look like?
