> The Origin of Life
>
> The origin of life is generally taken to be the outcome of
> progressive chemical complexification, This process presumably led
> from small organic molecules, such as amino acids, sugars, and
> nitrogenous bases, now known to be produced on a large scale by
> cosmic chemistry, to an organism called the LUCA, or last universal
> common ancestor, from which all known living organisms have been
> shown to be descendants. In spite of a considerable amount of high-
> level research, the nature of the chemistry used by the LUCA
> remains largely unknown. Consideration of the mechanism whereby
> early small-molecule chemistry may have changed into biochemistry
> suggests that life may have been launched by processes related to
> those used by cells today. If this is so, enzyme-like catalysts
> probably were involved. DeDuve will discuss the possibility that
> small peptides and other ?multimers? may have played catalytic
> roles in an era before large protein enzymes had formed, a view of
> the emergence of life that he has pioneered.
