Re: Natural selection
Really? So what would the pattern look like if it wasn't random mutations and natural selection which caused the divergences of species?
Well the pattern wouldn't look like a hierarchal nested tree that's for sure (unless the 'creator' was a blithering idiot that limited his own inventions).
When steering locks were invented by Toyota, they didn't just stay on Toyota's. When antilock braking systems were invented in 1929 in the aircraft industry they didn't stay just on aircraft. A good 'intelligent designer' will apply inventions across an entire product range if it is good.
Contrast that with the cephalopods versus mammalian eye. The cephalopods have eyes with the optic nerve connections entering from the back of the eye (optimal configuration), whereas mammalian eyes carry a mutation(s) that forces the optic nerve fibres to penetrate the retina and attach to the photosensitive cells from the front - in the way of the light which the receptor cells are trying to gather. This significantly reduces the light available to a mammalian eye through a simple engineering 'fuck up' (alias mutation).
It is very difficult to see why an omniscient creator would engineer that sort of balls-up deliberately into his creations - to give them sub-optimal systems - If a human engineer did that he's lose his engineering licence - and rightly so.
So - to repeat - the pattern of species based on a hierarchal development system is EXACTLY as predicted by the ToE and utterly not what should be predicted by an intelligent creator.
Simples really!

Re: Novel protein coding gene in an Antarctic fish
There's two SAS genes, and two antifreeze genes. Scientists noticed that some sections in the SAS genes look like some sections in the antifreeze genes. These are the facts. From then on these researchers interpret the facts according to evolutionary theory, without any backup evidence for their conclusions.
Their conclusion would be more believable if they proved that the organisms with the antifreeze genes came exclusively from a population that only had the SAS genes, unfortunately its only an assumption on their part that the antifreeze genes came from the SAS genes, based merely on similarity of sequences.

Scientists assume that what looks like paralogs are paralogs. They assume that the known process of gene duplication is responsible for pairs of genes that look exactly as if they are the results of that process. They assume that what looks like a frog is a frog, produced by the processes known to produce frogs.
Now, would you like to demonstrate the existence of another process that produces apparent paralogs
or apparent frogs?

Merely. Would you like to describe another known process other than duplication by which genes which appear to be duplicates can appear in the genome of a species. A known process.
And having done that, as it's your claim that all apparent parologs in genomes aren't paralogs, how are you going to set about showing that this is true?

Re: Natural selection
Really? So what would the pattern look like if it wasn't random mutations and natural selection which caused the divergences of species?
We would not see fewer non-synonymous mutations than synonymous mutations in genes. We would not see a nested hierarchy. We would not see the accumulation of mutations in junk DNA consistent with neutral drift. We would not see a correlation between ERV LTR divergence and phylogeny. In the pocket mouse example, we would not see less sequence divergence in the dark fur allele compared to the light fur allele. In those same pocket mice, we would not see different mutations in genetically isolated populations. Those are just a few off of the top of my head. I can list more if you like.
If a theory says that a mutation is random, and then if that mutation causes some of survival advantage the random mutation will slowly become the norm in a population, and then later that mutation will progress further through another random mutation-then what you would expect to see is functions in the organism which are controlled by 80 different genes? Did all 80 genes get mutated, and all 80 caused some type of slight survival advantage?
No two mutations are alike. For example, just one mutation is responsible for the change in foot morphology amongst the Vadoma people:
Atlas Obscura | Curious and Wondrous Travel Destinations
At the same time, a single substitution may have no impact whatsoever on morphology. It's not as simple as 1 mutation equals a set amount of change. Doesn't work that way.
And what if a function needs 7 different mutations before it even displays any difference in its functioning-why would the first six mutations be preserved in the populations before the seventh came about?
That would be the Texas Sharpshooter Fallacy.
Texas sharpshooter fallacy - Wikipedia
Evolution does not have a goal that it is striving towards, or a target it is aiming for. For every one function that requires 7 mutations there are billions that did not evolve.
I asked you what species of animal do you think the pocket mouse evolved from, which didn't have the function of producing melanin? You think it evolved from a creature which didn't have this function before? See its new and novel? Why are you so naive?
The dark mice evolved from light mice which required a gain of function. This gain in function was produced by random mutations followed by natural selection.
Why are you in denial?
This is again another one of your reading comprehension problems. They didn't come out differently at all.
Yes, they did. Their genomes were different due to random mutations producing divergence between genetically isolated populations.
Different mutations same results-not different results!
Different mutations, different results. Same phenotype.
Edited by Taq, : switch synonymous and non-synonymous. always get those backwards.

Re: Natural selection
Nested hierarchies means random mutations and natural selection?
A nested hierarchy is what we observe random mutations and natural selecton producing. Therefore, if life in the past evolved through random mutations and natural selection then life should fall into a nested hierarchuy, and it does.
What animal alive today is most closely related to humans?
The chimp and bonobo are the two species most closely related to humans.

Hi, Dash.

Look at human hair as an example. There aren't just a couple defined "colors" of hair: it's a gradient of shades. That's what you expect from polygenic traits: each individual mutation would have a subtle effect on the phenotype, so you can have any number of subtle shifts in color.
Bolder-dash writes:

The effect that a mutation will have on functionality depends on the exact nature of the mutation, so how can you know that it will take 7 mutations to change the phenotype? This implies that there are 7 genes that have the exact same function, which is unlikely. It's more likely that they would vary slightly, and each would have a subtle effect on phenotype.
Bolder-dash writes:

In Taq's example, the novel function is production of a new type of melanin.
Here's another, similar example: chicken eggshell pigments. Chicken eggshell color is a polygenic trait, like human hair, and traditionally varies from white (no pigment) to various shades of brown. But, there is an unusual breed from South America, the Araucana, that lays blue-shelled eggs.
This lay review of chicken eggshell color explains a lot of the details. Basically, blue eggs result from blue pigments produced in the "shell gland" (a gland in a uterus where the shell is synthesized). They are secreted as the shell is forming, so the entire shell is saturated in blue pigments. In contrast, brown pigments are only laid on the surface. So, the function of pigment secretion mechanism is different.
The blue-egg allele is a mutation to the oocyan gene (apparently, there are two point mutations, an A-to-T, and a T-to-A), which alters one step in the process by which eggshell pigments are synthesized. This alteration results in a blue pigment that is quite different from the typical brown pigments. The blue pigment is also secreted differently.
Interestingly enough, when you cross-breed blue-egg layers and brown-egg layers, you get a green-egg layer, which produces both kinds of pigments (blue saturating the shell, and brown layered on top). So, blue eggshell pigmentation is a new function that's added to the previous function, not an alteration that takes the place of the original function.

Well, I can see why you'd think that. But, the problem is that "increased complexity" (however you define it) isn't a mechanism: it's a phenotype. There's no reason to think every class of phenotype has to have a different mechanism. For example, unequal crossing-over is a type of mutation that can cause both gene deletions (decreased complexity) and gene duplications (increased complexity). So, we don't need two separate mechanisms.
The word complexity is a simple word (lol that's ironic). I don't see why its meaning should be limited to phenotypes in any manner. But pleeease do not start a sideline conversation on the meaning on the word.
Can you explain exactly what you think is happening here? Because, I think you've been duped by an offhand comment about the human nervous system (or its genetic components) being found in a coral. This is not what they found.
A "homolog" is a gene that two groups of organisms have in common. Homologs are not identical to one another: they are just similar enough in sequence and (sometimes) in function to be considered related in an evolutionary worldview. So, it's not like two unrelated airplanes both having Rolls-Royce Merlin engines: it's like two unrelated airplanes both having piston engines.
These researchers sequenced a bunch of genes (or, actually, sections of genes), and found that corals have more homologs with humans than with insects or nematodes. It doesn't say that corals have human genes or that humans have coral genes: it says that insects and nematodes are more different from other animals than other animals are from each other.
I'm happy with your piston engine analogy. The word "homolog" is a word used under evolutionary assumptions, under the assumption of baramins the similarities would be design similarities. I do not see any actual evidence that favors the homolog assumption above the baramin assumption.
Okay, now I need some clarification. I thought "increased complexity" and "additional coding genes" were the same thing, in your argument. This statement suggests that they are not always. Was I wrong?
You are wrong I was forced to use the word complexity in a manner that was measurable in another thread, and am happy to continue to apply it to only coding genes in this thread too if you wish, but the word has a much greater meaning.

All evolution needs is (a). How life got started is irrelevant to how life evolved once it was here. In the same way, what you learned in high school chemistry class will not change if we find that a deity magically poofed the universe into being.

Isn't it strange how the faithful use faith as a derogatory term. Funny that.

Apologies Bolder-dash, I'm often distracted by the side-issues but will attempt to ignore the other topics of the flood, abiogenesis, population movements etc I'm also on this thread regarding the origin of novelty, focussing on novel genes. Unfortunately evolutionists fail to see their circular reasoning even when you point it out, but that's really all they got, circular reasoning.

Well we both agree that life just appeared. We both agree on the processes of evolution.
So what are we discussing then if we are both in agreement?
The essence of my debate is whether genomes are evolved from baramins 6500 years ago, or evolved from a single common ancestor about 600 million years ago. Except for BlueJays nested hierarchy/fossil argument, I haven't seen much evidence for the evolutionist position.
