1 Origin and Evolution of Life

2

3 Electric discharges can generate organic molecules

4

5

6 The Murchison meteorite contains organic molecules e.g. D- and L- amino acids

7 Ribozymes and introns may be relics of an RNA world Peptide bond formation in ribosomes

8 Directed evolution: Artificial RNAs can polymerize ribonucleotides in vitro

9 Primordial replicases: RNAs may catalyze its own replication

10 A putative RNA replicase cycle

11 No Darwinian evolution outside of compartments

12 Compartmentalization may lead to accumulation of improved RNA replicases

13

14 A synthetic minimal genome

15 Living bacteria that harbor a synthetic minimal genome
