Living systems are a lot more complex than simple computer programs. Evolutionist can not back up their claims that evolution has to produce a nested hierarchy they can only assume it.
This is fundamentally wrong and I have shown you the evidence numerous times. At this point, I'm just going to stop engaging with you, because it's pretty clear you aren't going to understand this. A nested hierarchy only makes sense in the context of vertical gene transfer and divergent populations. I'm sorry, but at this point this is mathematically proven - in order to see this sort of parsimony within separated populations, it requires either insane random chance or for those populations to have diverged in the past. You can
test this yourself using random mutations in a DNA string and cladistic algorithms. I welcome you to do that. Find situations where the cladistics algorithm
doesn't produce a natural, parsimonious nested hierarchy with divergent ancestral populations, or
does with completely unrelated strings. You just can't do it, and we know exactly why.
Why, it only took me 10 seconds to find that and a hundred others.

I'm not quite sure what this paper is saying, but it doesn't seem to be "mutations are non-random".
This one does, but it's talking about cancer, not reproduction, which offers fundamentally different challenges. We
know the mutations that lead to cancer are not entirely random; that's how we can classify certain things as carcinogenic or not!
Why would a random mutation form a nested hierarchy - it's random, we would expect to see chaos
Because this randomness is, to some extent, conserved. It's not like the whole genome fluctuates wildly with every generation. Keep in mind we're talking about
populations, not individuals, and at a population level, some mutations will be selected against and some mutations will be kept. Although even in vastly simplified models, where such things as gene conservation are not taken into account, you will still get consistent nested hierarchies, as the CDK007 video makes perfectly clear.
So at the beginning, we have one population. This population undergoes various mutations. Then, that population splits, and all of the mutations thus far are conserved by each of the two groups. Then, each of these groups undergoes various mutations. Now, consider a separate group, which started with the same genetic material but was completely distinct from the start. It undergoes random genetic mutation. Will its genetics appear similar to the other group? No. Given the random nature of the mutations themselves, similar mutations might be
selected for (assuming these groups had the same selection pressure), but you will not end up with the same pattern of similarities and differences that you would among the first group, or its divergent branches. However, those divergent branches
will show a pattern of similarities, because they both got those specific mutations from their shared ancestor.
This is a large part of why this:
when nested hierarchies are observed to occur in breeding pairs
Is not a viable model. These nested hierarchies occur far,
far above the level where your proposed mechanism would work.
You do realize the only empirical observation we have is of breed mating with breed producing new breeds (variation) within the species, do you not?
The fact that we can observe this nested hierarchy throughout all of nature, and that it concords with morphology, with individual genes, with embryology, with ERVs... All of this is empirical observation that points to one thing and one thing only: common ancestry. Yes, in the last few hundred years that we've been looking, we haven't seen massive divergences in morphology. We wouldn't expect to. But to claim that there is no empirical observation of common ancestry as a result is completely wrong and ignores the strongest and most important evidence evolution has to offer.
Now lets look at what the Brooker says: "Obviously we cannot take a time machine back 4 billion years and determine with certainty how these events occurred", This approach has led researchers to a variety of hypotheses regarding the origin of life, none of which can be verified".
Abiogenesis is a field in its infancy; actually establishing what the first lifeforms looked like is almost impossible, given that they were almost certainly microscopic soft cells that would not leave much in terms of fossils. Brooker is right; the origin of life is still largely an unknown. This does nothing to detract from the theory of evolution, which deals with life after it has started to exist.
Here is something about "catastrophic floods have periodically had a major impacts". Interesting that catastrophism finds its way into the Biology book.
Catastrophism is well-accepted at this point, as it's blatantly obvious that catastrophic events can have massive regional or global effects. Volcanic activity pulled us out of snowball earth; a meteor impact killed off the dinosaurs; Yellowstone erupting could spell the end of human civilization... However, none of this grants any credibility to the long-debunked idea that sometime in the last 10,000 years there was a global flood. The difference between things like the meteor impact that killed the dinosaurs and that global flood is that we can find strong, independently verifiable evidence of the former, while the latter
should have left a ton of evidence, but somehow didn't leave any trace of its passing whatsoever.
Then we look at the "Cambrian explosion occurred in which there was an abrupt increase". So what does catastrophism and explosions have to do with slow gradual change over time? Here we are told: "The cause of the Cambrian explosion is not understood".
The Cambrian explosion was an "abrupt increase" in
geologic terms. It lasted around 20-25 million years. That's not some sudden explosion, and there's nothing about it that requires any sort of supernatural explanation. The cause is, as stated, not understood, but again, it's hardly a critique of evolution that we don't know everything about prehistoric earth.
Terms like we cannot determine with any certainty, none can be verified, may have formed, may have originated, may have evolved, the cause is not understood. I do not think biology is so sure of what they believe. I see no indication at all of a 99% agreement. Just the opposite actually.
What you're missing is that none of the things we're unsure about are particularly crucial to the theory. It's like not knowing the exact mass of the meteor that struck the dinosaurs - does that somehow pose a problem for Newtonian mechanics? No, of course not. The precise origin of life has nothing to do with the theory of evolution. The cause of the cambrian explosion is tangentially linked, and may offer us some insight, but the fact that we don't know exactly why there was such an increase in complex multicellular life is not significant to the core of the theory.
It's this core - descent with modification, genetic mutation, and universal common ancestry - which has such complete agreement. The exact formation of the taxa, the precise evolutionary history of every lifeform on earth, the exact mechanisms of genetic change, the taxonomy of long-extinct relics known only by a few skeletons... these are all things we can examine with evolution's help, but the fact that we don't know everything is not a contraindication to those core ideas, as every single piece of evidence we have ever uncovered fits the theory.
"a precise definition of species is not always possible". Yet evolutionists love to gourd Christians over what their definition of a kind is. Yet they do not seem to have any real definition of their own.
This is because the concept of "species" is necessarily fuzzy. The line between species A and species B in the same genus is generally not a line; it is a continuum, and understanding speciation merely in terms of "can they interbreed" is a flawed way of looking at it - sure, a lion and a tiger
can interbreed, and even produce halfway fertile offspring, but in the wild, they almost never will - they are geographically separated, and don't
want to interbreed. Given more time and geologic separation, this ability to create viable offspring may disappear entirely, but drawing a hard line at that point will be exceedingly difficult.
The concept of a "species" is to an extent necessary to discretize nature. However, what we're inherently doing is placing hard lines within a continuum, and that's always going to be problematic. However, there are numerous criteria we can look for when trying to judge whether or not something is a species. "Kind" isn't even well-defined, but even if it were, it leaves no room for correction or nuance, and certainly not for the rainbow spectrum of life we see.
There is no real alternative to evolutionary biology in the education system, so of course
they would agree. They have been deeply conditioned into the ideology of science itself, thats
what the education system is designed to do.
The "ideology" of science? Science is not an ideology. It's an
epistemology. It is a way of knowing things. Furthermore, it is the only consistently reliable way of knowing things that I am aware of. The application of science has moved us from a group of nomadic hunter-gatherers on the savanna to essentially the dominant lifeform on the planet. The reason we teach science is because of how universally and demonstrably
useful it is.
The first and greatest assumption that science by default accepts, is that there is no
interference in the natural world by God. Science is forced to hold this assumption,
otherwise, if a God did interfere in nature, then any study and measurement of nature
would be at best be an unreliable exercise.
I agree - if there was a supernatural element, we could never rely on anything to be consistently true. You know what's funny about that? We
can rely on things to be consistently true. Gravity never spontaneously stops working for a while. Humans never give birth to dogs. There's never an organism with saltwater taffy where its chromosomes should be. So basically, the fact that science works is a very strong indication that there is no significant supernatural interference in nature.
Okay, okay, leaving the humor behind, science works from the basis of methodological naturalism. That is, it makes the very basic assertion, "If there
is a supernatural cause for something, we have no way of investigating that cause", and draws from that conclusion that it should only examine
natural causes. This cannot be ignored. If we allow for the supernatural, we're just stuck. We have no idea if that aspirin actually worked, or if it was just god fiddling about, and maybe tomorrow it will cause blood to shoot out of your ears. So while science accepts that it is
possible that the supernatural exists, it goes forward under the (entirely justified) assertion that only natural causes can be examined.
Indeed, if it didn't, it probably wouldn't work as well as it did. Supernatural explanations for what we observe in nature consistently
fail. They, without a single exception, are either proven wrong (Lightning is gods being angry, this drought is because of god, this plague is demons and we need to pray, epilepsy is demon possession) or are left in the position where they cannot possibly provide any evidence for their assertion (god as the prime mover, etc.).
The second assumption that science must hold onto at all cost. Is that all events in the
distant past occurred at the same rate, and over the same time period, exactly the same
as these events occur in the present era. If these events in the past took place in a shorter,
or longer time frame, then the time frames for dating would be erroneous.
...What? Science makes no such assumption. Just for example, it's often claimed that science "assumes" that C14 rates were the same in the past... But it doesn't. In fact, we
know that C14 rates were different in the past, and we calibrate our dating methods to account for that. Don't take this personally, but you seem to have a very,
very weak grasp on what science is and what the method says. Before you go about criticizing the methods that have built this modern civilization, without which you would not be able to disparage it to the whole world at near light-speed, maybe you should learn a thing or two about it.
