Why run from reailty? Why is it that you are the one that never does
anything to support your stupidity?
I actually started to look the junk up, but something came up and I had
to save and post what I had. It didn't take me any time at all to go to
the ID perps creationists propaganda site and just search Behe and whale
devolution.

The second paper is an in-depth look at genetic changes associated with
the evolution of the cetacean (whales and dolphins) lineage. This is the
kind of amazing work that is now possible in our brave new world of
relatively easy genome sequencing. The authors compared the genomes of a
half dozen different cetacean species to scores of other mammalian
genomes. So did they find some jazzy new cetacean molecular machinery?
Or complex, constructive changes in the whale genome to explain its
fantastic change in shape and lifestyle?
Well, no. They found a lot of devolution.
We found 85 gene losses. Some of these were likely beneficial for
cetaceans, for example, by reducing the risk of thrombus formation
during diving (F12 and KLKB1), erroneous DNA damage repair (POLM), and
oxidative stress–induced lung inflammation (MAP3K19). Additional gene
losses may reflect other diving-related adaptations, such as enhanced
vasoconstriction during the diving response (mediated by SLC6A18) and
altered pulmonary surfactant composition (SEC14L3), while loss of SLC4A9
relates to a reduced need for saliva. Last, loss of melatonin synthesis
and receptor genes (AANAT, ASMT, and MTNR1A/B) may have been a
precondition for adopting unihemispheric sleep. Our findings suggest
that some genes lost in ancestral cetaceans were likely involved in
adapting to a fully aquatic lifestyle.
Adaptation by Breaking Things
A couple of points:
1) At least 85 changes — and probably many more — were needed for whale
evolution. That’s a whole lotta intermediates that somehow didn’t get
stuck in adaptive dead ends, or persist for very long.
2) As I explain in Darwin Devolves, adaptation by breaking or blunting
genes is expected to be very much faster than constructive evolution, so
it should dominate all evolutionary time scales. As the current paper
helps to show, the evidence for that is growing. Not only is devolution
the dominant mode in microevolution we observe in real time in lab
experiments today, but also in the macroevolutionary change that we
infer from genome sequences over geological ages — punctuated by bursts
of new information. There is no hint of significant, constructive
Darwinian molecular changes at any time scale.

If you look up the paper you find that the "microevolution" of the 85
changes span the evolution of whales from land to their aquatic
lifestyle, and they occurred around 50 million years ago. This was
devolution to Behe, and it obviously was not a micro change that
occurred during the loss of these genes. A lot was obviously evolving
in these lineages.

Unlike William A. Dembski[25] and others in the intelligent design
movement, Behe accepts the common descent of species,[26] including that
humans descended from other primates, although he states that common
descent does not by itself explain the differences between species. He
also accepts the scientific consensus on the age of the Earth and the
age of the Universe. In his own words:
"Evolution is a controversial topic, so it is necessary to address a few
basic questions at the beginning of the book. Many people think that
questioning Darwinian evolution must be equivalent to espousing
creationism. As commonly understood, creationism involves belief in an
earth formed only about ten thousand years ago, an interpretation of the
Bible that is still very popular. For the record, I have no reason to
doubt that the universe is the billions of years old that physicists say
it is. Further, I find the idea of common descent (that all organisms
share a common ancestor) fairly convincing, and have no particular
reason to doubt it. I greatly respect the work of my colleagues who
study the development and behavior of organisms within an evolutionary
framework, and I think that evolutionary biologists have contributed
enormously to our understanding of the world. Although Darwin's
mechanism – natural selection working on variation – might explain many
things, however, I do not believe it explains molecular life. I also do
not think it surprising that the new science of the very small might
change the way we view the less small." Darwin's Black Box, pp 5–6.

When haven't you done something similar to what I just did, and why
would it be required of me and not yourself? Do you ever wonder why you
spend so much of your life running from reality? You should know all
this, but denial and willful ignorance is just a way of life for you.
