Evolution teaches that all organisms are related to one another. Yes, that includes poison ivy, mosquitos, and even strawberries! For proof of this idea, evolutionists point to DNA similarities.
When Bill Nye the Science Guy visited the Ark Encounter several years ago, he and Ken Ham got into a discussion about these genetic similarities. When Ken asked Bill if human beings were related to bananas, Bill responded, “Yes!”
Bill Nye the Science Guy might see DNA similarities as proof of a common ancestor, but creationists don’t. Instead, we know that if God created all creatures on Earth to live and thrive on the same planet, then He was wise enough to design them with similar DNA.
DNA Similarities: Proof of Evolution or a Divine Creator?
Evolutionists frequently say that similarities in DNA sequences provide evidence that all organisms (for example, human beings and chimps) are related.
If you go back far enough, they say, you’ll find that all living things come from one ancestor.
Of course, this doesn’t align with what we find in Genesis 1-2.
The Bible makes it clear that God didn’t use evolution to create diverse organisms from one ancestor. Instead, He made all living things according to their kinds.
So then how do Christians explain the similarities in DNA?
When we look at genetic similarities, we see patterns that point to one Creator.
Humans do the same thing with their own designs. If you study an artist’s complete body of work, you’ll certainly find similarities among them. For example, in nearly all of Van Gogh's paintings, there are certain similarities—his style is consistently dramatic and imaginative. Put a Van Gogh and a Rembrandt next to each to each other, and it's easy to tell which is which.
Chimp and Human DNA: Not as Similar as Evolutionists Thought
Ever since Darwin’s time, evolutionists have studied the physical similarities between humans and apes. They analyze their hands, skulls, faces, how they use their limbs, and so on.
Since then, molecular biologists have added their own ideas to the mix. Over the last few decades, they’ve pointed out similarities in DNA sequences between humans and apes. Some estimates put the genetic similarities between humans and chimps as high as 98.5% to 99.4% identical.
That’s why evolutionists refer to chimps as our “closest living relative.”
When the whole chimpanzee genome was mapped out in 2005, scientists realized the similarities were actually only as high as 96% with a difference of 4%. Still, though, they touted this as confirmation of Darwin’s theory.
The problem with this assumption, though, is that it overlooks just how vast the differences are. That 4% represents 35 million differences, says Dr. David A. DeWitt.
Factoring in the 40-50 million bases present in humans that chimps don’t have (and the same number in chimps that humans don’t have), Dr. DeWitt puts the total number of DNA differences at about 125 million.
“Creationists believe that God made Adam directly from the dust of the earth just as the Bible says in Genesis 2,” he says. “Therefore, man and the apes have never had an ancestor in common. Assuming they did, for the sake of analyzing the argument, then 40 million separate mutation events would have had to take place and become fixed in the population in only 300,000 generations. This is an average of 133 mutations locked into the genome every generation.”
This number is staggering! Certainly, there are simply too many differences between humans and chimps for them to be related as evolutionists claim.
Trusting God’s Word as Our Ultimate Authority in Genetics
Observational science—including studying human and animal genomes—can tell us a lot about a creature as it is right now. But it can’t tell us about its origins.
When any scientist, whether an evolutionist or a creationist, starts talking about an organism’s origins, they’re always using their biased worldview to interpret the data.
For evolutionists, of course, their biased worldview hinges on evolution, and it drives every assumption they make about organisms having a common ancestor.
Yet for creationists, that worldview rests on the Word of God. When it comes to interpreting data, we use a biblical lens to understand an organism’s history. And according to the Bible, humans and apes are in no way related to each other. God created them both separately on Day 6 of Creation Week.

In this fascinating video, Dr. Purdom dissects the evidence found in DNA for clues to its origin. Not to spoil the ending, but what she finds reveals that evolutionists’ claims are greatly embellished!
