Document Summary
Chapter 11: the origin and evolution of early life. 11. 1 origin and diversification of life on earth. Because of this, no direct observations from phylogenetic methods in the present can explain other organisms beyond luca. This hints at how the building blocks of life may have come into existence. 11. 2 the rna world: what are the features of the rna world hypothesis, rna world hypothesis states that around 4-3. 5 bya the genetic world was completely. Spiegelman; sumper: the results showed that natural selection took place in the replication of the rna sequences giving a method of how rna could have evolved, show how the genetic building blocks of life may have evolved. Each facilitates the replication of the other in a closed loop: a b c d a. the more a present, the faster b will replicate. At some point the cell would become too big and begin to buckle or the cell could split into two cells.
