The evidence of human-chimp genome similarity
1. For the past several decades, the standard has been that humans are 98 percent genetically identical to chimpanzees.
2. The well-known chimpanzee genome paper published in 2005 provides a genomic similarity of only about 80 percent when the discarded nonsimilar data are included and only 70 percent when the estimated size of the chimpanzee genome is incorporated. [1, 2]
3. Geneticist Richard Buggs took an exacting approach in calculating genome-wide DNA similarity using data from both the 2005 chimp genome report and the human genome project in a brief news report published in 2008. Because Buggs’ estimates closely match the outcome of this study, his work is quoted below.
“To compare the two genomes, the first thing we must do is to line up the parts of each genome that are similar. When we do this alignment, we discover that only 2,400 million of the human genome’s 3,164.7 million “letters” align with the chimpanzee genome—that is, 76% of the human genome. Some scientists have argued that the 24% of the human genome that does not line up with the chimpanzee genome is useless “junk DNA”. However, it now seems that this DNA could contain over 600 protein-coding genes, and also code for functional RNA molecules.”
“Looking closely at the chimpanzee-like 76% of the human genome, we find that to make an exact alignment, we often have to introduce artificial gaps in either the human or the chimp genome. These gaps give another 3% difference. So now we have a 73% similarity between the two genomes.”
“In the neatly aligned sequences we now find another form of difference, where a single “letter” is different between the human and chimp genomes. These provide another 1.23% difference between the two genomes. Thus, the percentage difference is now at around 72%.”
“We also find places where two pieces of human genome align with only one piece of chimp genome, or two pieces of chimp genome align with one piece of human genome. This “copy number variation” causes another 2.7% difference between the two species. Therefore the total similarity of the genomes could be below 70%.”
“This figure does not include differences in the organization of the two genomes. At present we cannot fully assess the difference in structure of the two genomes, because the human genome was used as a template (or “scaffold”) when the chimpanzee draft genome was assembled (Buggs 2008).”
4. The details of a research study in which the individual chromosomes of chimp were compared to their counterpart in human is available in a privately published, but well-documented and freely available report (Progetto cosmo 2012). This effort employed an algorithm that involved the random selection of 10,000 30-base sequences from the query (chimp chromosome) and then determined their identity based on a query against their human chromosome counterpart. Excluding the Y chromosome, this study came up with an average 63% DNA identity (similarity) genome-wide.
5. The preliminary analyses of Buggs (2008) and Progetto cosmo (2012) indicate that in conflict with evolutionary claims, overall chimp DNA similarity compared to human may be as low as 70% or less.
6. Hypothetical evolutionary processes cannot explain the extremely broad differences between chimp and human DNA when the whole genomes (full DNA sequence of an organism) are considered.
7. The similar regions between genomes indicate the basic reuse of effective code what is known and done by software engineers. Expert DNA engineering in nature points to the Great Designer or God, who has manufactured all the wondrous diversity of life on Earth, and who bridged the gaps between the species.
8. God exists.

DNA Doesn't Lie -- and that includes Gorilla DNA: It turns out that 15 percent of the gorilla genome is closer to humans than to chimps! Bob and Fred point out that for many decades Darwinists have claimed that humans are closest to chimpanzees. So this throws yet another monkey wrench into the theory of evolution. The "puzzling surprises..." are reported in Nature. "The standard view of the great-ape family tree is that humans and chimps are more similar to each other than either is to the gorilla — because chimps and humans diverged more recently. But, 15% of human genes look more like the gorilla version than the chimp version." The guys also review the enormous and unpredicted difference between the human Y chromosome and the chimp Y, and the human genome generally with the published comparisons of the sponge genome, a worm, and the kangaroo genome!
Gorilla joins the genome club
But the genome sequencing has thrown up surprises, too. The standard view of the great-ape family tree is that humans and chimps are more similar to each other than either is to the gorilla — because chimps and humans diverged more recently. But, 15% of human genes look more like the gorilla version than the chimp version.
Much of the 15% is in sections of the genome that do not code for proteins. But the researchers also looked at functional gene changes. They found that certain genes — including some involved in hearing and brain development — had gone through more rapid changes than expected in both the gorilla and human lineage.
In Dr. Kuhn's view, this poses a problem for Darwinian evolution because the "[t]he ape to human species change would require an incredibly rapid rate of mutation leading to formation of new DNA, thousands of new proteins, and untold cellular, neural, digestive, and immune-related changes in DNA, which would code for the thousands of new functioning proteins."
And if someone tells you that chimps and humans share a common ancestry remind them that even with a difference of a mere 1% (it's actually much more) that's 35,000,000 base changes by point mutation. The last common ancestor between human and chimp is supposed to have existed 6 million years ago, at 20 years per generation that's 300,000 generations.
To go from the last common ancestor to us requires 117 point mutations to be fixed in the population every generation. Evolutionist Haldane proposed that it would take 300 generations for 1 point mutation to become fixed in a sexually reproducing organism. 117 (or 58 if we split the two family trees) would lead to inevitable error catastrophe in the organism as harmful mutations (am estimated 90% of mutations are harmful) would accumulate faster than natural selection could eliminate them (although as Sanford explains in Genetic Entropy and the Mystery of the Genome, natural selection doesn't really do much against gradual accumulation of harmful mutations) as laid out by Walter Remines in The Biotic Message.
Basically, once again, we see evolutionists appealing to magic rather than science.
