nOrganisms
look designed for at least three reasons:
nRedundancy - A Designer can
engineer redundancy into a system,
but chance is unlikely to do this. An
example of this is the
presence of degeneracy in the genetic code and other features that minimize or negate the effects of many
point mutations
nExcess potential - Organisms have
potential that may never be
used. For example, Wallace,
co-discoverer of natural selection,
pointed out that primitive people have the capacity to do calculus when trained. Natural selection is unlikely to select for capacity that is not used
nComplexity - Life exhibits a
kind of complexity that it is hard to
produce by processes involving chance
