ID musings

[Robin Leech]

Familiarity breeds.
Keep in mind that it was over 1 billion years ago when
the former bacterium became symbiont chloroplasts in the
larger cell (just as mitochondria and nuclei became
symbionts), and agreed to convert sunlight to usable
chemical energy in order to live in a nice cushy cell.
No "faster" protein was needed cuz its abundance
filled the need.  There has been no selection for a faster
enzyme in nature cuz it is not needed.
It is the human mind that puts grades or quality on things,
not nature.  In nature, if it isn't competing, it dies out.
