Here is an example of how the catabolic / anabolic motor of evolution
might work.
The example concerns how endosymbiosis led to eukaryotic cell
development.
First this is the basic idea I suggest.
The two biochemical processes, catabolic and anabolic, are
1. separate (to better regulate and give more flexibility) and
2. they are in what I call a 'symbiotic arms race'. This dynamism
propels each side
to catch up with the other's developments and changes, as natural
selection does in predator and prey in nature.
Here's an example of how I think it worked.
Catabolic biochemistry and anabolic biochemistry are separate but work
together.
The cell took in bacteria that became symbiotic and supplied the
catabolic
energy that mitochondria do.
This plus on the catabolic side would suggest that there is now
pressure on the anabolic side to match it.
What better proof is that then the start of eukaryotic cells that
arose from this symbiosis?
The change on one side , pressures the other side to catch up and or
allows
it to develop.
Thus evolution has a direction - toward better catabolism and
anabolism. And a motor to get it there - the 'symbiotic arms race'
between the two relatively separate biochemical pathways.
