From Savely Savva:

Re: Study suggests how DNA building block might have formed (Nov. 2, 2007): The electric/electromagnetic interactions -- the only currently known in chemistry -- obviously cannot explain emergence of the pre-life organic molecules, let alone life itself. Searching for the yet-unknown fundamental physical interaction(s) responsible for life can be and must be the subject of physics. See

Look at the Urey-Miller experiment and refer to a chemistry text, and you will see that organic molecules form from inorganic ones all the time, given only energy. There is no mystery here, it is all just chemical bonding.

"Organic molecule" is just a classification invented by human beings to describe things, not something outstanding or different. The chemistry and physics is all the same. Even in deep space, immense clouds of organic molecules exist.

The only daunting thing about life is how complex most of it is, not that there is something fundamentally different about its chemistry. Life is nature's own nanotech, and we are rapidly closing in on its secrets.
