The appropriate follow-up YouTube video on all of this is about Chaos Theory and Complexity in Nature.
This superb quality six part BBC Documentary is called:
"The Secret Life of Chaos Part (1 - 6)"
It deals with the one simple question: "How did we get here ?"
It follows on from the profound works of mathematician Alan Turing (mentioned in post #1).
Between the six part documentary in Post #1 and the one mentioned above, one cannot help but be stunned at the breadth and depth of scientific theoretical understanding human beings have achieved in these deep questions.
I highly recommend spending the time to look over these documentaries as they are fairly easy going, presented from a historical perspective, and visually enrolling.
Cheers
