Less is More

Evolutionary biology firmly asserts that all change is brought about and sustained by random mutation.

Homo aspens have 23 individual chromosomes. Chimpanzees have 24 individual chromosomes. There is strong evidence to suggest that 2 of the chimpanzee’s chromosomes were fused together to create what is referred to as homo sapien’s chromosome #2.

Homo sapien’s #2 chromosome is a combination of 2 smaller chromosomes (referred to as 2a & 2b) in the chimpanzee.

This reduction in the number of chromosomes shuts off the ability of other primates to breed with homo sapiens.

A problem with Evolutionary Biology.

More of This We Know & More of This We Will Tell

The event –

The perfect fusion of 2 chromosomes into 1 is a very rare event. There is no known transmission mechanism to explain how two chromosomes are fused into one. A lot of stuff has to take place for something of this magnitude to occur. A change of this order is light years away from what is usually referred to as a random mutation. One could almost refer to the perfection necessary to bring this about as “The Immaculate Conception”.

Evolutionary biology firmly asserts that all change is brought about and sustained by random mutation.

Sexual reproduction places an additional burden on evolutionary biology to explain all change by random mutation.

Sexual reproduction requires a breeding pair.

So the miraculous event, the fusing together of two chromosomes into one, has to have occurred in at least two primate members, and these two primate members have to have been of similar age and geological proximity to mate. That this would occur randomly is doubtful.

The skinny

1. Reducing the number of chromosomes in homo sapien cut it off from successfully breeding with other primates.

2. That the fusing of two chromosomes into one happened in a breeding pair almost certainly can not be classified as a random event.

Mutant Gene

Misspelled vs. Misspelt

Because of the nomenclature – mutant – most have misvisioned the biological unit responsible for change – a mutated gene. Most when conceiving of a mutated gene imagine a section along a chromosome that under magnification would look misfigured, somewhat like a piece of fruit that has spoiled or a unit that is much larger or smaller than its peers. This would be an abnormality of one of the 4 basic DNA construction units – C, A, T, G. To my present knowledge, abnormal nucleotides do not make it into the DNA configuration. This is perhaps due to the inability of the deviant to match.

Collins, in his latest offering – The Language of Life – brings needed clarity to the concept of a mutant gene when he uses the improved nomenclature – “misspelled” to refer to a mutant gene.

Genes code for amino acids.

I before E except in Meiosis

A gene is a long, linear, string of 4 nucleotides – C,A.T,G. The exact order of the components in the string have been shown to be important. A mutant gene is actually a gene in which their has been a deviation in the order of the nucleotides in this string i.e. instead of a C perhaps there is a T or a nucleotide has been left out or an additional nucleotide has been added. Hence the genetic word has been misspelt.

There is no way to independently just looking at a section of DNA and determine whether it contains altered material. There is no apparent visual deformity. A sample must be tested against a known to determine deviation.

Genetics 115

Historical Continuity and Doctrinal Consistency


Genetics is a fascinating subject. One can only take notes at first and hope that with time a pattern will emerge.

Homo sapien has 23 individual chromosomes. Note : One can not predict anything based on just knowing, ex ante, the number of chromosomes an organism has. i.e. a chimpanzee has 24 individual chromosomes.

A chromosome may be thought of as a linear Velcro strip. Along this Velcro strip one finds sequences of protein coding genes. In total, homo sapien has about 20,000 protein coding genes attached to the above mentioned 23 chromosomes. Note : One can not predict anything based on just knowing, ex ante, the number of genes an organism has. i.e. a ringworm has 19,000 protein coding genes.

Into far darkness gone.

Hail Holy Light

Obviously, it is the arrangement of the organic material and not the absolute number that is important.

Notes on genetics –

1. There is a correlation to parts of the Bible and genetics.
2. Sexual reproductions is very conservative. Sexual reproduction makes it much more difficult to introduce change.
3. Males are more prone to mutation than females.

All three of the above are tantalizing subjects. Because of time constraints I am only going to address (3.) today.

There are 2 genetic observations that establish that the genetic material of the male is more prone to mutation.

1. Male spermatozoa are continually being produced. A female, after about 6 months of development has all the eggs she is ever going to have. There is no continual meiosis taking places, as with the male, to continually produce new eggs from old. This drastically reduces transcription error in the female.

An additional point of interest is that up until the moment of conception the male sperm is haploid but the female egg is diploid. It is only after egg fertilization that the female egg undergoes meiosis. As of yet, no one has commented on the rationale for this strategy.

2. Females are XX while males are XY. The singularity of the male Y chromosomes means that if the Y chromosome is damaged there is no additional copy to suggest alternatives.
