Change leads to Change

To make the set of (necessary) causal relations, aluded to in the last post, more explicit:

1 There is, due to selection or chance, evolutionary change.
2 This changes the properties of the organisms of a population.
3 This changes the relation of the organisms and their environment.
4 This changes the set of selection pressures acting on the population.
5 Leading to further change.
(repeat)

Ergo: there can be a whole series of evolutionary changes, macroevolution, due to selection, apart from any environmental change.
