“'The basic hypothesis is this,” Davies says. “We have fundamental laws of information that bring life into being from an incoherent mish-mash of chemicals. The remarkable properties we associate with life are not going to come about by accident.”

"The proposal takes some unpacking. Davies believes that the laws of nature as we know them today are insufficient to explain what life is and how it came about. We need to find new laws, he says, or at least new principles, which describe how information courses around living creatures. Those rules may not only nail down what life is, but actively favour its emergence.

"Davies suspects that information is the answer because it seems increasingly fundamental to both physics and biology. In recent years, physicists have shown that information is more than the bits and bytes that course through computers. Information can be converted into energy, for example, such that physicists now build little information engines and information-powered refrigerators, if not with the appearance their names suggest.

"Similar machines are found in biology. Constructed from proteins, they chunter away inside living cells where they manipulate information at the nanoscale. “What we’re seeing in the lab is these two worlds colliding in a very practical way,” he says. “The physics is really connecting with the biology and that’s why I think we’re on the verge of this great new revolution.”

"Davies believes that life will turn out to bear telltale patterns of information processing that distinguish it from non-life. Few people would argue that a computer is alive no matter how the ones and zeroes zip around inside it. What Davies suspects is that life exploits, and arises from, particular patterns of information flow. (my bold)

“'When you look at a living system, the way information is managed is very far from random. It will show patterns that could lead us to a definition of life,” he says. “We talk about informational hallmarks and these might be used to identify life wherever we look for it in the universe.”

"Most radical, though, is Davies’s proposal that any laws of information that shape life might favour its emergence too. Under this scenario, life would not arise on habitable planets by random chance but would be nurtured by “biofriendly” rules. It is the kind of teleological argument that many scientists reject, but one that Davies cannot help finding attractive.

“'People often say that the probability of life forming by chance is so low there must have been intelligent design or a miracle. I find that anathema,” he says. “Religious people have got to move on and get away from the idea that there’s a superbeing who fits it all up. What I find more congenial and much more intellectually respectable is the notion of fundamental laws of organisation that turn matter into life – a life principle built into the laws of the universe.”

"He concedes: “It is wishful thinking because at this stage I can’t demonstrate it. But if we live in a universe in which the emergence of life is built into it in a fundamental way then we can feel more at home in the universe. It’s no substitute for a caring superbeing watching over us. It won’t help us deal with the problem of death, and it doesn’t help in a moral crisis, but it would certainly be more comforting than to believe we live in an empty, sterile universe.”

Comment: this is not descriptive information. it is instructional information both as to structure and appropriate reactions to stimuli. Without this onboard information life would cease to exist. And what created this information? My answer is God. Information without a source is impossible.
