No it can't. There were only many small adaptions, not stages. Stages also suggests that there is a next stage to evolve to which is not correct.



You are conflating 'evolution is directionless' with 'no stages'. Stages can only be seen when looking back at the evolutionary history.

For example:

Study reveals human body has gone through four stages of evolution (http://www.eurekalert.org/pub_releases/2015-08/bu-srh083115....)

http://www.pnas.org/content/112/37/11524.abstract


Stages are a human abstraction that help us understand and make sense.


You can say that for just about everything
