The first example of an experimental autocatalytic set was created in 1994 in the lab of Günter von Kiedrowski . This system consisted of two short nucleotide sequences that mutually catalyze each other’s formation from even shorter fragments. The catalysis was due to complementary base-pair formation.
In 2004, a 9-member autocatalytic set of peptides was created experimentally by Gonen Ashkenasy . In 2012, autocatalytic sets of long nucleotide sequences, with up to 16 members, formed from shorter fragments in the lab of Niles Lehman . A very different, but also autocatalytically self-replicating molecular system that forms from a combinatorial library is actively being studied in the lab of Sijbren Otto.
These results represent exciting progress on the experimental side. However, most of these systems were carefully designed, starting from already existing polymer fragments. One particularly big challenge currently still remaining is to have autocatalytic sets emerge spontaneously in a laboratory setting from more basic building blocks. Further experimental studies of the currently existing systems, and steps towards a more spontaneous emergence and evolution of autocatalytic sets are part of the current collaboration.
