Recent Discoveries in Genetics

May, 2007

Several recent discoveries in genetics reveal even more of the amazing properties of the genome and give additional evidence for the design of life by an intelligent creator. DNA consists of a long sequence of four nucleotide bases. Proteins consist of sequences of about twenty amino acids, and are specified by a coding system in which three successive nucleotide bases of DNA constitute a “codon” and are translated into a specific amino acid. However, there are more codons than amino acids, so more than one codon corresponds to a given amino acid in many cases.

Now, within everyone’s DNA are “SNPs”, single nucleotide polymorphisms. This is a site at which many humans have differing nucleotides. Sometimes such a difference does not influence the amino acid coded for. For example, the codons UCU and UCC both code for serine, so a change of uracil to cytosine at this point in the RNA, corresponding to a change of thymine to cytosine in the DNA, has no effect on the sequence of amino acids in the protein. Is there then any difference between such codons in terms of their effects on the organism?

Man or Ape: Which are You? Which do You Choose?

O Timothy, keep that which is committed to thy trust, avoiding profane and vain babblings, and oppositions of science falsely so called: Which some professing have erred from the faith. Grace be with thee. Amen.” I Timothy 6: 20-21 (KJV)

As we approach this topic, I want to remind us of Paul’s admonition to the young Christian, Timothy, to make strong efforts to keep his faith. Dr. Henry Morris in his commentary on these verses in his annotated The Defenders Study Bible points out that “Science falsely so called” is in the Greek, literally “pseudo-science” or “pseudo-knowledge."

Puzzles of the Genome

December, 2006

The genome of an animal contains the DNA that specifies the characteristics of the animal. This is in the form of a sequence of four bases; the sequence of the human genome is over three billion bases long. Of course, different individuals have different sequences. A few years ago the human genome project completed a description of the sequence of the human genome, and several other animals’ genomes have been sequenced since then. Scientists sometimes claim that these genomes provide evidence for the theory of evolution. However, recent results show how little we really know about the genome, and therefore it is unreasonable to assert that the genome provides evidence for evolution, when we understand it so poorly.

Does the Molecular Evidence Prove Common Ancestry is a "Fact?"

November, 2006

Genesis 1 describes the separate creation of various organisms “after their kind.” This means that all life on earth is primarily related through having a common creator and not through common descent. When evolutionists claim that molecules-to-man macroevolution is a “fact”, they are often referring to evidence for common ancestry irrespective of any evolutionary mechanism. This approach helps them avoid the inherent difficulties associated with explaining how point mutations, genetic recombinations, gene duplication, and natural selection could create new genetic information by chance. One way evolutionists try to support the idea of common ancestry involves comparison of homologous DNA sequences and proteins between organisms (molecular homology). Presumably, the greater the similarities between DNA or protein sequences in different organisms, the more recent has been the divergence from a common ancestor. Two lines of molecular evidence will be explored in this report: comparisons of cytochrome c and endogenous retroviral elements (RVEs).

Evolution - Impossible to Embarass its Believers

Henry M. Morris, Ph.D. Late Founder and President Emeritus of ICR

Dr. Henry Morris wrote this article for Acts and Facts, the monthly publication of the Institute for Creation Research (ICR), shortly before he died on February 25, 2006, at the age of 87. His messages, as was this article, were always clearly stated and well referenced from the Bible and the scientific literature. I believe God gave Dr. Morris a long life to be a courageous, intelligent messenger to help us understand that truly objective scientific observations and evidences support the Genesis account of creation, that we can rely on this account as the true Word of God, and that God is our Creator. Dr. Morris spent his life to help establish and strengthen our faith in God so that we can wholeheartedly believe in Him, accept His gift of our Savior, Jesus Christ, and go forward joyfully in His grace unto good works as he did.

How Old Is Humanity?

June, 2006

There are a number of evidences that the human race is very young. For example, in an article in Science, 1 the age of the human race is is estimated to be 1,000 to 10,000 generations:

"...1000 to 10,000 generations old, which is roughly the age of the human population,..."

Figure 1

We review some evidence for the youth of the human race, including recent findings concerning mitochondrial DNA mutation rates that give even a much younger age than 1,000 generations.

Intelligent Design

May, 2006

The phrase "intelligent design" is heard a great deal lately in the media, usually in the context of secondary school science education.

Faith and Science: Friends or Foes

October, 2014

My wife, Cassie, and I went on a three week trip to the northwest this past July and August. 1 During the Alaskan cruise portion of our trip, we attended an intelligent design (ID) conference sponsored by the Discovery Institute (http://www.discovery.org) entitled “Faith and Science: Friends or Foes?” Afterwards we visited Mount Saint Helens in Washington, then Yellowstone and Glacier National Parks. As you can imagine, the scenery was beautiful.

The purpose of this article is to communicate the content of the talks given during the ID conference based on the notes I took. Occasionally, I will comment on the speaker’s thoughts. These comments will appear in italics and prefixed with the word ”comment.” 2

On the Origin of Humans

April, 2015

One of the key issues in the creation-evolution debate is the origin of humans, Homo sapiens.

What we think about the origin of our own species has a dramatic impact on our morality and wordlview because it answers the questions of who and what we are and why we exist. The secular and biblical views of our origins are diametrically opposed and must come to totally different conclusions about our place in the universe. Secular scientists tell us that the evidence that we evolved from a common ancestor with primates is “overwhelming.” But just how good is that evidence? The Bible teaches we were made in God’s image and designed to have fellowship with Him both now and forever. Recent results in the field of genetics have been remarkably in accord with the biblical model for human origins and inimical to evolutionary scenarios. Here we will compare the biblical and secular models for human origins and discuss recent science that supports the biblical view and/or discredits the evolutionary view. Specifically, we will discuss “junk DNA” as “evidence” for common ancestry, the real percent similarity of the human and chimpanzee genomes, the alleged historical fusion of two primate chromosomes that “prove” humans share common ancestry with primates, genetic evidence that Homo sapiens and Neanderthals interbred and were hence the same species, and genetic evidence that is consistent with Adam and Eve as well as Noah and his family.

Creation Ministries Creation 2015 International Superconference

October, 2015

Dr. Dan Reynolds attended the recent Creation Superconference held in Myrtle Beach, South Carolina July 13-17. Dr. Reynolds has provided us a summary of each of the sessions at the conference.

My wife, Cassie, and I recently spent a week in Myrtle Beach where I attended 19 of 20 talks on creation and related topics given at the Creation Ministry International (CMI) Creation 2015 Family Superconference. Cassie, while supporting my interest in creation, only attended one session and spent the rest of her time sewing on her portable sewing machine in our hotel room! The conference was held at the Springmaid Beach Resort located right next to the ocean. The accommodations, food, and staff were excellent. Mornings and evenings were filled with talks while afternoons had options for free time, a tour of a nearby aquarium with Dr. Robert Carter of CMI, or playing chess with Jonathan Sarfati, former chess champion of New Zealand. And as usual, there was an extensive bookstore offering hundreds of books and videos, often at reduced prices. I came home with a couple of bags full!
