This problem has puzzled biologists and physical scientists ever since.
Living things are hugely complex and have unique properties, such as self-maintenance and apparently purposeful behaviour which we do not see in inert matter. So how does chemistry give rise to biology? What could have led the first replicating molecules up such a path? Now, developments in the emerging field of 'systems chemistry' are unlocking the problem. Addy Pross shows how the different kind of stability that operates among replicating molecules results in a tendency for chemical systems to become more complex and acquire the properties of life. Strikingly, he demonstrates that Darwinian evolution is the biological expression of a deeper, well-defined chemical concept: the whole story from replicating molecules to complex life is one continuous process governed by an underlying physical principle. The gulf between biology and the physical sciences is finally becoming bridged.

What is Life?: How Chemistry Becomes Biology PDF
In 1944 Erwin Schrodinger published a little book with the title, `What is Life?' Though, obviously not the first to pose this question, it is purported to have provided at least part of the inspiration to those, such as Watson and Crick, who would later go some way to answering it.
Addy Pross, though using the same title, adds the sub-title, `How Chemistry Becomes Biology' and this is quite odd as he spends most of this very slim book attempting to persuade the reader of exactly the opposite; i.e. that biology is simply a sub set of chemistry, or at least its natural extension. His justification for this curious and, I imagine irritating - at least to biologists, strangely naļ¶„ claim is his depiction of the transformation from non-living to living matter as a two stage process the first of which, the abiological phase, which is governed, principally, according to the established laws of chemistry, results from the autocatalytic replication of organic molecules such as RNA resulting in replicating networks or primitive forms of embryonic proto-life. The second, biological, phase is governed by the `rules' of evolution as elucidated by Darwin leading to an increase in organic complexity and the biodiversity we see today.
