Ongoing debates: Universal biology as the principle cause?
fourth view claims that all possible life anywhere in the universe is
constrained in some ways and so shares a common universe-wide fitness
landscape. Universal chemical and physical laws dictate what elements and
compounds can be used for what purposes, for example, water is likely to be
present in all life. These constraints on life may be so tight that some of the
solutions found in terrestrial life will turn out to be the only ones that are viable.
This would mean that life could only occur on approximately Earth-like planets,
and importantly, that life on Earth is an instance of a universal biology.
This view supports the opposite conclusion to the one arrived at by Monod; the
driving force in terrestrial biological history has not been primarily chance,
but is in part necessity, i.e. natures adherence to universal laws.
