Pity that our resident YEC science expert chose only a single sentence in this post to respond to with insults and conservative incel name calling:
The fascinating science of genetics, a relative newcomer in the quest to understand 'how?' and 'why?', is still greatly misunderstood.
Wow - do tell!
If there is interest, i can attempt to clarify and explain some of the complex nuances of our genetic makeup.
"Analysis of DNA" shows very little similarity, in the actual genes' - like that?
Would you like a different perspective and analysis of the facts of science, or do you prefer the memorized dogma we were all force fed at school?
Ah, the old 'dogma' canard. Let's what your 4 decades of study can show us.
There are many false perceptions:
1. Lego block homogeneity. 'All genes are the same! We can just rearrange them or snap one in to another to change organisms!'
Wow, I don;t remember being taught or reading that anywhere at any time. The 3 different textbooks that I have used over the years in my Genetics classes don;t indicate that anywhere.
Do you have a reference so we can verify this is in fact "dogma we were all force fed at school"?
Is it your studied opinion that brand new genes are required for phenotype variation?
2. 'Percentage of similarity proves common descent!'
Also never seen this presented as 'dogma.' In fact, texts that I am familiar with explain that this is not so, and that while the percent similarity is obviously indicative of the ancestor-'descendency' relationships, to borrow your word (that is, for example, how your Canid mtGenome paper did one of its analyses - the NJ method groups taxa by a pairwise similarity algorithm. But you knew that, given your 4 decades of study.
It is, in fact, the unique shared mutations that are far more informative for such things. And these are what processes like Bayesian and Likelihood and maximum parsimony methods employ.
3. Obfuscating techno babble with vague, undefined terms, and ambiguous concepts proves common descent!
Right. Like how creationists use one definition of haplotype, and every actually educated and experienced geneticistis/biologist uses another.
But it is so odd- after 40 years of study, I would think that the 'technobable' is no longer a mystery to you. I stopped being flabbergasted by field-specific terminology when I took a medical terminology class as a freshman in college. Didn't address all 'technobabble' but made it easier for me to parse new words. You should take such a class.
Here is a creationist 'technical' paper - so much technobabble - who are they trying to fool?
Snake Hybridization: A Case for Intrabaraminic Diversity
by Glen Fankhauser, M.S., and Kenneth B. Cumming, Ph.D.
Abstract
Snakes have rarely been examined as examples of intrabaraminic variation due to the relative obscurity of knowledge regarding the subject of these secretive animals as well as the relative newness of the breeding of snakes. North American species of snakes of the genera Lampropeltis, Pituophis, and Elaphe, while classified in separate genera may actually be more closely related than evolutionary biology predicts.
This study examined intergeneric and interspecific hybridization of several species of colubrid snakes through the use of both natural breeding methods and scent disguise to fool the different species to interbreed. Eleven different species of three different genera were used in this experiment. Results of the crosses were as expected to resemble midpoints of color and pattern between the parental species. Banding patterns appeared to be dominant over blotches and stripes. The most interesting finding was that the amelanistic varieties of the California kingsnake, L.g.californiae, and the corn snake, E.g.guttata are apparently allelic forms of amelanism regardless of the fact that these snakes are members of different genera. When the two genera were crossed this albinism appeared in the F1 generation. All types of the hybrids produced were viable and fertile. As such, they are most likely examples of intrabaraminic diversity of created “kinds” rather than evolutionary speciation. This paper adds viability, homologous genes, and pigment variations to the list of character space criteria for recognizing baramins.
Oh my gosh, the technobabble for the purpose of obfuscation!!! IntrabaraWHOOO???
Close scrutiny and analysis of the FACTS of our genetics makes concluding common descent more problematic than ever. The facts do not align with perceptions.
Expand please. Show your work.
Here is a repost of #99, which was likely lost in the flurry of heckling and indignation, that this topic seems to attract.
"Here is a graphic that shows the structure of the chromosome.
I think perhaps the main problem is in understanding the complexity & inflexibility of the genetic structure.
"Inflexibility"? What do you mean by that?
Any 2 humans differ by about 160 million bases.
is that not flexibility?
You cannot just take chromosomes from one organism, & plug them into another, or fuse them, or split them, to 'create' a new organism, with different genetic makeup. That is scientifically impossible, yet it is the central assertion of the ToE.
Again, I have never heard this, read this, or been taught this.
You will need to explain what you mean and provide references to have this assertion taken seriously.
Here, for example, we see a HUGE amount of synteny bewteen human and chimp genomes (
synteny being, in effect, the degree to which organisms share genome architecture).
The genes WITHIN the chromosomes are completely different, & do not correlate.
This is false. It is at odds with what is actually seen in human/chimp comparisons. See above.
Similarity does not imply descendancy.
It did when it was seen in mtGenomes in your Canidae post - why the double standards?
Here is a primer on molecular phylogenetics - odd that in your 4 decades of study you never came across what such studies actually entail.
As I've already mentioned, shared, unique mutations are more informative than just plain old % similarity.
That is where the science of genetics has given us a more complete understanding of living things."
If there is interest, we could examine the complexities of dna, and the building blocks of life.
Sure - I cannot wait to see your treatment of the "complexities" of DNA. I am sure the content of this post is a good indication of the level of up to date sophistication we can anticipate.
I might suggest that among the reasons your initial posting of this did not garner much response is the amount of misinformation it it made it seem to much of a burden.
