But that's the point being made ... given a number of
components that can produce an effect, time, reproduction
and chance mutation can have effects which were not intended
and yet, in hind sight, give the impression of design.
The circuit (in terms of the precise connection pathways)
evolved via a process which is modelled upon the supposed
evolutionary scenario. And the end result utilises a 'component'
as an antenna which did not originally have that intended
purpose.
Selection criteria aimed at a particular result, actually had
an unexpected result.
And something VITAL to the operation of the circuit as a receiver
was originally in place for a completely other purpose.
Remove a component and the thing doesn't work as a receiver ...
but it did evolve.
Doesn't that cast some doubt on IC as a concept related to design?
And again, abiogenesis and evolution are not the same.
