The simian chromosome 12-13 fusion to human chromosome 2 theory is a favorite of the evolutionists. However—even if it were true (of which there is new evidence for great doubt)—it would be very heavy evidence in favor of …
- non-common ancestry between humans and monkeys
- and very great evidence for common ancestry only for:
- humans between humans and…
- monkeys between monkeys.
Here’s how that works.
What the evolutionists don’t highlight is the following:
Yes, human chromosome 2 bears some color-bar-pattern resemblance to the two ape chromosomes 12 and 13. But two bits of pure logic kill the whole idea that it can mean anything positive for the common-ancestor theory.
First, it is no surprise that ape chromosomes should look a lot like human chromosomes. Of all God’s created Kinds, the monkeys look the most like us, have the most similar physiology and biochemistry—and so it would follow with the common-design theory (as well as the common-ancestor theory) that simian and human chromosomes should have a similar look, structure, and function…just to the exact same degree as our bodies would have a similar look, structure and function.
The similar color-banding is neutral and transparent to the argument (although common-ancestry folks are in denial of the obvious reality that these features support both models).
Second—and this is the most significant—the “fused chromosome 2” does NOT appear in any living or fossil ape lineage. And it DOES appear in every living or fossil human lineage.
So when did the fusion take place?
To match the actual evidence the fusion theory would require a fantastically unlikely timing for the event.
The fusion would have to occur right at the time of the common ancestor — not a generation before! — not a generation after!
- If … the fusion happened before the imagined common ancestor—then there would be some simians that would also have inherited the fused chromosome … unless you want to pretend that all of those just happened to be the lineages that went extinct without a trace.
- And if … the fusion happened after the imagined common ancestor—then some humans should also exist that do NOT have the fusion … again, unless you want to pretend that all of those just happened to be the lineages that went extinct without a trace
… to make your theory look not impossible.
Plus, the newest evidence does not support the fusion at all
- Telomere ends are usually 15-20 thousand base-pairs in length.
- The middle of human 2 where telomeres are claimed to have merged … is only a mere 700 base-pairs … instead of the 30-40 thousand that would be expected, if the theory were true.
- This sequence also seems to be part of a functional gene.
- And the regions of the supposed two centromeres (a normal chromosome only has one, and it is in the middle) … are part of truly functional genes that see a lot of transcription activity and so are useful. Centromeres are only structurally functional to the chromosome and are not transcribed like this.
Note: This matter came up in a debate I had with an evolutionist professor who was the Faculty Sponsor of the Atheist Club at Marshall University in Huntington, WV.
If you would like to see the video of the debate between Dr. Jackson and Prof. Mays (Tues July 17, 2018) go to the FB page for England Hill Free Will Baptist Church in Catlettsburg KY.
Skip through the first 35 minutes since there was a known problem with the sound and so the debate really didn’t start until then.
