This is in response to the June 24 letter "Natural selection not the whole story." I believe it is important to counter the claims of this letter. It sounds like a well-researched essay but is nothing more than a series of "cut and paste" arguments from creationist articles.
"Science has yet to discover any reliable method for adding genetic information to the gene pool." Yes we have. They are called mutations. Most mutations are neutral, while some are harmful or beneficial. Neutral and beneficial mutations add information to the genome. "Archeologists have conclusively proved no transitional fossil forms, yet many heralded as transitional forms have been subsequently disproven." Archaeology is the study of human cultural remains; Mr. Erickson means paleontologists. Science cannot prove the nonexistence of anything. The fossil record is resplendent with transitional forms. All of the vertebrate classes have wonderful transitional series. Creationist literature lies by denying their existence.
"Law of biogenesis" demonstrates that life does not arise from non-living matter, i.e. maggots created from cow dung. It has nothing to do with the abiotic origin of life. "Law of entropy." This is a misunderstanding of the Second Law of Thermodynamics, which states the amount of entropy must increase in a closed system. Earth is not a closed system. "Law of information." This is Shannon's 1948 "mathematical theory of communication," which says nothing about information only coming from intelligence. These are distortions from creationist literature.
The list of scientists rejecting evolution is plagiarized from Henry Morris. Keplar, Linnaeus, Newton and Pascal died before the theory of evolution existed. Louis Pasteur said about virulence, "unless nature, in her evolution down the ages (an evolution which, as we now know, has been going on for millions, nay, hundreds of millions of years), has finally exhausted all the possibilities of producing virulent or contagious diseases, which does not seem very likely." Does that sound like he rejected evolution?
Theodosius Dobzhansky said "Nothing in biology makes sense except in light of evolution." All available evidence supports evolution. Evolution as a scientific theory is constantly expanding. Creationists falsely claim that evolution contains many flaws and is in question by the scientific community. It is my duty to teach evolution as a fact. I am not denying viable alternates but exposing them to the only theory that explains the biological world.
