Don, Of course you can continue to play the reductionist way and say that
the cell is a complex of mitochondria, peroxisomes,spirochetes and
whatever. And all these bacteria are in turn...., etc.etc.. The problem is
one of hierarchy, of more complex organisation of the parts. By reducing
complexity to its atoms you do not explain it., you only create flat
mechanistic models.You loose the qualitative aspect which is supremely
important, especially when you speak of the bag of protozoans called Homo.
A cell in an organism does not compare to a free-living cell, even when
you keep it artificially and feed it as an embryonic stem cell., for your
devious human needs. .
