What those Galapagos finches don’t teach

Darwin observing natural selection
of finches with different beaks,
thought this a picture of life’s evolution,
but there never was any brand new information
– all types of beak-form had always existed,
but one shape of beak suited one situation
and another a different climatic condition
and in each population
only one finch variety
prospered and multiplied
so each group experienced a loss of diversity,        
less flexibility for specialisation:
you could call it a gradual and slight devolution.

For new information to somehow arise
is genetically difficult, so it is no surprise
that no-one has ever observed it,
just selection and small variation
(and sometimes a change caused by damaging mutation),
so tweaking, no major big modification.
