Negative Mutation lessoned by the Catabolic and Anabolic Split?

2010-03-09T16:39:41Z

Before, I've suggested that a positive mutation on the Catabolic side
might spur the Anabolic side to catch up - or vice versa - a positive
mutation on the Anabolic side might spur the Catabolic side to catch
up. Thus for every positive mutation you have two improvements, and a
sort of motor to push natural selection. We have the term 'arms

We carry more than just a single mitochondrial genome type.

Mitochondrial genomes are not uniform across cells of the body as
previously believed, but vary between different tissue types, according
to a study published online today (March 3) in Nature.

You once mentioned the fact that flies undergo dormant periods that
you associated with sleep. I thought that was the most interesting
observation that you ever posted. However, you mentioned it only in
passing.
1) Could you speculate on how reductionism and synthesis is related to
sleep in flies?
2) Could you provide citations on "sleep" in flies?

That is true, however is a very incomplete picture. No existing
species (except for humans) has the nurturant instinct to care for
slow-maturing youth past the absolute minimum for survival, and the
sooner the better. Developmentally retarded or helpless individuals
are abandoned to predators, you would not expect paedomorphic features

The catabolic anabolic split hypothesis may also help explain Cope's
Rule about size increase in evolution.

This quote from Paul Davies well sums up the importance of looking at
life as either catabolic or anabolic processes:
"There are two paths in investigating the world: the reductionist path
and the synthetic path.
I would add there are two paths to all life the reductionist path
(catabolic) and the synthetic path (anabolic).

I am interested in evolution, not medicine and certainly
not alternative medicine. I suspect there are others in this forum who
feel that way. May I suggest that you tie all your posts to natural
selection and heredity. Further, you should broaden your examples a
bit. Get away from mammals for a while.

By understanding why we sleep, we may resolve many chronic health and
psychological problems. Many of these problems may be directly
connected to the two transition points of a daily digestion cycle -
wake to sleep, and sleep to wake.

I have to make a small correction.
Birds lost their teeth after their split with the dinosaurs. For
example, archeopteryx still had teeth. However, it is considered more
bird than dinosaur.
Birds and theropods (two legged meat eating dinosaurs) are
difficult to distinguish. There are some theropods that already lost

JE:-
I agree, however it is useful to separate them to get a handle on the
problem. I think a big problem is that once separated most forget to put
them back together again.
JE:-
Ok but how can they be separated within empirically testable hypothesis?
JE:-
International trade with respect to foods reduces this in human populations.
