It may not be necessary for complex organic molecules to assemble out of nothing in a finely tuned primordial soup. Two recent studies to illustrate this:

1. Simple chemical droplets can divide and multiply in the right conditions: https://arxiv.org/pdf/1603.01571v1.pdf

2. “Evolution” from that simple beginning may be enough according to the theory of dynamic kinetic stability: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3843823/
