A=B, B=/=C, So therefore A=C!

This isn’t so much a creationist point in the book, just good view of the contradictions in the book.

Let’s start with this paragraph on page 616 of the book in the chapter about heredity.

Cystic fibrosis (CF), one of the most common hereditary diseases in the United States, is caused by a recessive gene. A child must receive the recessive gene from both parents before this respiratory disease manifests itself. Receiving a CF gene from only one parent makes the child a carrier. Roughly 10 million Americans are carriers of CF; thus the disease has a gene frequency of about 1 in 25 Americans. If any 2 of those 10 million people have children, the children may suffer from this disease.

Seems like pretty legit biology to me. I mean, that’s about what I learned in my general biology 1 course in college. Now let’s take a look at page 630 in this book, in the chapter entitled DNA: The Regulation of Life in the section about mutations.

Mutations that are passed from generation to generation also have harmful effects. Relatively minor mutations have been responsible for causing albinism, or lack of skin pigment, in people and animals; a near absence of feathers on chickens; extra fingers or toes on people; wrinkled skin and near hairlessness on mice; and other harmful effects. More serious hereditary mutations cause such diseases as cystic fibrosis, hemophilia, muscular dystrophy, PKU, sickle-cell anemia, and Tay-Sachs disease. Mutations are part of the meaning of the Scriptural observation that “the whole creation groaneth and travaileth in pain together until now” (Rom. 8:22).

Now, I’m no medical expert, but I do know that though these diseases did start out affecting humans due to mutations in the alleles that carry the genes, but more than half, and in the case of hemophilia two-thirds, of each case of these diseases are now hereditary, and not original mutations. I would consider that to mean the diseases are now hereditary, not mutations as a whole.

If there are any medical type people reading this blog and I am dead wrong, please inform me at wtfchristianbiology@gmail.com and inform me how I am wrong. Please have legit information, and not just telling me I’m wrong.
