Most people consider the most ancient abiogenesis in terms of chaos tending toward selected functions. According to this view, originally, random sequences produced functions that were then selected. Thus, evolution proceeds from chaos to order.
tRNA (the crowning achievement of abiogenesis) shows that this view is not completely correct.
Remarkably, tRNA originated from ordered sequences: repeats (GCG, CGC, UAGCC repeats) and inverted repeats (stem-loop-stems).
The most ordered tRNA sequences are found in ancient archaea, which are similar to LUCA (the last universal common cellular ancestor). In more derived archaea and bacteria, tRNA sequences are more changed in evolution.
