Dan:
You're talking about selective breeding, not natural selection. In
fact, selective breeding leads to a species being less able to adapt
to changes, less able to fight off illness and infections, and more
prone to genetic diseases. Charles Darwin wrote about this
extensively. He told a story about how an animal breeder informed him
the quickest way to alter a animal was to cross-breed it with its
sister or brother, or to back-cross it with a mother or father. But
this ultimately leads to a weaker species.

So no, while on the surface it may seem we have altered evolution by
selective breeding, we have in fact effectively bred Dynamic Quality
out of the equation. By determining what traits we select for, the
Dynamic freedom exhibited in the wild is lost.

Perfect.

Incestual crossbreed brings out the best unknown traits in the offspring.
But!!, it will also bring out the worst case scenario's.The number of bad
mutations will spice up real far.The Jack Wattley discus fish is a good
example of incestual breeding and crossing back.
Perfect results for in a fish tank, no changes of survival in the nature.
Nature will filter them back out if tried.

Or try the Pigeon blood discus as example, or the Malboro's or the
leopards,or the 'degen-discus', changeless in nature,...(visability for
predators.)

Same goes for Koi really, most are very beautiful, but taken back to nature,
the visability for predators is simply to high.And they lost the ability to
protect themselves to cancer mostly.

Think of the Orchid hybrids(F1 Hybrids), Maize,(F1 Hybrids)...chanceless
outside a controlled monoculture.
The breeders are clever,However, they kill immediatly all results that are
unwished,and mostly will deny it.


But i do have to say, the field Ian is coining,Epigenetics, is  a very
interesting and promising field.But a change and a modification,will almost
never become a mutation.
Checked it out in the Kew gardens dbase.solid. good field.
