Human Chromosome 2 From a Design Perspective

Even before the release of "Science and Human Origins" there has been an uproar over human chromosome 2, the alleged fusion of two other chromosomes (still found in other primates) and sharing a common ancestor with chimps. According to evos this was supposed to be a chromosomal fusion that occurred in some gamete and then got passed along- a random event.

However if we look at it from a design perspective the randomness disappears. Why? Chromosome/ DNA packaging and chromosome territories.

Ya see gene expression and regulation depend on both the packaging and the location of the chromosomes within the nucleus, ie chromosome territories. And if you have two different/ separate chromosomes then they can be packaged differently and ferried around separately also, meaning they can be separated and placed in different territories.

So perhaps with humans it is required that the information never be separated. And the easiest way to accomplish that was by splicing the two together. Snip off the excess and splice.*

The research would be to determine where HC2 resides in certain tissues and cells and during development and then compare with the two primate chromosomes for the same tissues/ cells and stages of development.

So HC2 is explained as a design feature, for humans. It not only helps with reproductive isolation but it also allows for a different gene expression and regulation pattern necessary for the different requirements of humans.

* it could also be that the two chimp chromosomes were the result of splitting HC2 into two separate chromosomes
