In the most cases where adaptations and minor evolutionary changes are
observed it's not because new information is added to DNA, but rather
there is a loss of information.

Bad mutations seems to be the rule.
The male sperm count is decreasing
with each generation. Each year new and previously unknown genetic
diseases are occurring just in humans. With the passing of time, there
is little doubt that our DNA, our genetics is become increasingly _less_
perfect. The Homo-sapiens species is believed to have arrived on the
scene 200,000 years ago, given the increases in genetic disorders we
observe today, it's highly _likely_ that the DNA of our early ancestors
were far closer to perfect that any of their decedents. Therefore, from
this evidence one can deduce that the proofreading and repair mechanisms
themselves are in a declining state with each generation becoming a bit
less perfect than the preceding generation. It's possible we saw this in
the extinction of Neanderthal species.

Beneficial mutations are rarely observed. The defective mutations are
overwhelming the beneficial mutations, as evidenced by the increasing
list of genetic disorders. Perhaps, this explains the 99% extinction
rate of all life forms that ever lived as observed or recorded in the
fossil record, as well as the numbers of the species become extinct
today. of course, human involvement accounts for some of this extinction
such as passenger pigeons, the dodo bird and the Tasmanian tiger. But to
your point the proofreading and repair systems are not perfect. But
without deliberate design how did the proofreading and repair systems
come about in the first place?
Of course there is educated, guesses,
suppositions, hypothesis and theories, but no one _knows_.
question is where is the man holding hold Occam sword? Has he been
barred from entering this room of science?
