[Paleopsych] is evolutionary change stockpiled?

[Steve Hovland]

Extending the software analogy,
an accounts payable system does
not mutate into accounts receivable.
It becomes a better payables system
as a result of enhancements.

Then one wonders, what is the genetic
equivalent of a complete redesign and
rewrite of a computer application?

One reason the Unix system is so good
is that many of its utilities have been
rewritten several times, each from a
better basis of understanding.

What do you get when you apply
this to organisms?
