Mutations accumulate by being added through time and passed from offspring
to offspring. Most mutations remain buried within the genes, or are
corrected by DNA repair systems. When mutations do show (phenotypically
expressed), they are almost always harmful and are selected against. The
more mutations do accumulate in populations, the greater the probabliity
they will show up phenotypically and jeopardize the organisms. But plants
and animals are thriving and are not in jeopardy from mutation loads.
Therefore, it is reasoned, the biological world could not have vast
antiquity.

It is common knowledge that apple tree's can be grafted but is this
mutation or selective breeding? There is an intelligence at work here not
a random chance mutation.

Thanks for the answer, if this is so then why are there still amphibians?
And why is the cycle not broken by mutation?

All the examples of mutation you mentioned are very questionable. Do
mutations occur yes. Are there examples of selective breeding between say
dogs to dogs or horses to horses yes but isn't that micro not macro
evolution? I thought we were talking about fins to feet? The most
questionable comments you gave as evidence of mutation resulting in
something good may just as well be inherent in the DNA structure from the
begining of its creation.

The man who has probably devoted more study than any other man to
experimental observation of mutations, said:

"But mutations are found to be of a random nature, so far as their utility
is concerned. Accordingly, the great majority of mutations, certainly well
over 99%, are harmful in some way, as is to be expected of the effects of
accidnetal occurrences."
