Michael Behe: Darwin Devolves

We should note that Behe believes in an old earth and common descent. He is not a Biblical creationist.
It has been known, in general, that "nearly all" mutations are detrimental. I put "nearly all" in quotes because, to date, no one has observed a mutation that is not detrimental, with possibly one or two obscure mutations. So, for purposes of discussion, all mutations are detrimental.
That does not mean that a mutation is not beneficial. There can be a short-term benefit that helps the organism, but overall the organism has lost information and is less fit. In his book one of the examples Behe uses is that of sickle cell anemia. The benefit is that it provides immunity to malaria. The drawback is that the DNA has been seriously damaged with the following effects (quoted from the Mayo Clinic web site):
The above is quoted from: https://www.mayoclinic.org/diseases-conditions/sickle-cell-anemia/symptoms-causes/syc-20355876
In his book Behe comprehensively lays out the biochemical proof that mutations degrade the organism (defined as a loss of information at a minimum) and over time lead, not to an improved organism, but a dead, extinct organism. In other words, the process we call evolution (the General Theory of Evolution), does not exist. Evolution never happened and never could happen. We are devolving (going downhill). Behe' biochemical science is good, but what is missing is a credible explanation that accounts for the diversity of life and all that we observe. We were designed and created perfect by God, and through our sin all life has been damaged and is now degrading. That's what the Bible says, and that is exactly what we observe.
God created us, and we will be accountable to Him.
The gospel is not social justice nor serving others. The gospel is love in action... Jesus Christ giving Himself so that you can be saved from the wrath of God.
Now I make known to you, brethren, the gospel which I preached to you, which also you received, in which also you stand, by which also you are saved, if you hold fast the word which I preached to you, unless you believed in vain.
For I delivered to you as of first importance what I also received, that Christ died for our sins according to the Scriptures, and that He was buried, and that He was raised on the third day according to the Scriptures, and that He appeared to Cephas, then to the twelve.
After that He appeared to more than five hundred brethren at one time, most of whom remain until now, but some have fallen asleep; then He appeared to James, then to all the apostles; and last of all, as to one untimely born, He appeared to me also. - 1 Corinthians 15:1-8
