Are these statements correct? Could they be better expressed?


Local entropy can decrease in an open system with an input of free energy.

Free energy alone is not sufficient to maintain or further decrease low 
local entropy: an energy capture and transformation mechanism is also 
needed.

Extant life *maintains* low local entropy through its organisation and 
processes.

Evolving life *decreases* low local entropy through the ratcheting 
mechanism natural selection acting on random mutations in instances 
where that evolution increases functional complexity and organisation.

There is no other known mechanism apart from natural selection that does 
this. For example, neutral drift alone increases entropy.
