The idea
Natural selection, per Bio 0055 and Bio 2229, adapts a population to its environment; it sets no final goal and grants no higher rank.
In practice
A bacterium alive today is as evolved, by elapsed time, as any vertebrate, despite very different structural complexity.
Where people slip
"Humans are the most evolved animal," per Bio 2311, imports a ranking natural selection does not produce.
