So you assert. In the previous post i address the false equivalency of this argument. There is a MAJOR difference between simple variability, & the assertion that major leaps can be made between distinct genetic types. Appealing to time has no scientific validity, as no mechanism has been defined or observed that can make this even possible, whether you have millions of years, or minutes.The only differences between micro evolution and macro evolution are the amount of time it takes for one versus the other to occur, and the fact that neither are scientific terms, being inventions of creationists, not evolutionary scientists. Moreover, evolution doesn't strictly explain how species adapt to their environment. Evolution is a scientific explanation for the origin of species. It is the process by which different types of living organisms are thought to have developed and diversified from earlier forms during the history of the earth. That process knows no boundaries in time, even though time is a vital part of the process.
So I assert? So the scientific community asserts. All of it. Evolutionary scientists do not make distinctions between microevolution and macroevolution because there are none other than the time it takes for one to occur over the other. The evolution of species is what you call "microevolution" whereas the evolution of new genera or above is what has been labeled macroevolution. It is a false dichotomy. In reality, they are one and the same. They occur via the exact same evolutionary processes (i.e., natural selection working on the genomes of life forms passed on from parent populations to offspring populations). The only difference is the length of time it takes for one to occur over the other. The only reason creationists attempt to make this distinction is because they know full well they cannot make a valid scientific argument against the origin of species, and because they object to the facts of the ancient age of the Earth; and since it takes so much longer for new genera to emerge than for species to emerge, they cannot accept anything that runs counter to their young world beliefs. So they reject their own pre-defined label of macroevolution. It is the ultimate straw man argument and has no scientific merit simply because there is no evidence to support it.
If you ignore all the evidence to the contrary, I can see how you would come to that conclusion. You are trying to restate the watchmaker analogy, an argument that was refuted over 80 years ago. There is such a mechanism that explains how life evolved; and that mechanism it is natural selection. But evolution has no arrow, nothing that requires one species to be more complex than the one that precedes it. One look at the fossil record will show you that some species become LESS complex than their ancestors, while others become more complex. It all depends on to what the species is adapting. If a species is adapted to life both on land and in the water, and the water dries up in the region as it becomes more arid, and continues to become more and more arid, the adaptations for life in water will, over time, become non-functional, or disappear altogether. Genetically, however, the genes for adaptation to life in the water will still be there in its genome, but have become non-functional. If the region becomes a wetlands once again in another era, those genes could reactivate, and allow for a new species that is once again adapted to life in water. We see this in frogs as well as other species.
usfan said:So you assert. Natural selection only explains variation. It does not contain any mechanism to allow the vertical jumps to more complexity, as is proposed. We know a lot more about genetics than we did in the 1800s, & it is not so simple to create 'The Island of Dr Moreau'.
So the entire scientific community asserts. Natural selection explains ALL of the diversity of life. It not only explains how species can become more complex, it also explains how species become less complex. Yes, we do know a lot more about genetics than we did in the 1800s. Which is why no one (but you, that is) is arguing from the point of view of 19th century literature.
usfan said:There is also no evidence of less complexity. Species can devolve into less variability, with fewer traits at their disposal for adaptation, but they do not change genomes or move down the evolutionary scale. A horse remains a horse. It does not become a monkey or a fish.
Indeed, because if a horse could become a monkey, that would refute evolution. You've managed to present two straw man arguments in one post. That indicates a rare talent for bullshit. The ancestors of whales possessed rear limbs because they were land living quadrupeds that, over time, evolved into semi-aquatic species, that eventually evolved into fully aquatic species, evolving not only new species, but new genera and new families as well. During this transition (which, by the way, is very well documented in the fossil record), hind limbs and pelvic region are reduced in size and functionality until we get to the fully aquatic species, which have but residual limbs, all internal, completely non-functional because they don't need them anymore. This is not an example of so-called devolution, since there is no such concept in evolutionary science. It is an example of natural selection acting on genes via epigenetic switches to modify body parts. In this case, the limb bones were redundant, and not only unneeded, but were actually impeding the new species ability to swim after pray. we see the consequences of these changes not only in the gross anatomy of all of the transitional species leading up to the whale, we see it in the genome of whales themselves.
Now, before you attempt to counter this evidence, you must know that I have worked on whales, and have a broad knowledge of their biology. Here is one specimen (in the background) that I studied in minute detail and am expert on this specimen:

usfan said:You only assert that there are 'genes for adaptation'. That is another argument with the 'looks like' qualifier. If there is a gene for a particular trait, it will be in the dna. If some dna 'looks like' something from another dna, that is coincidental, & can not be shown to be causal.
I made no such assertion. Genes do a lot of things. The most important thing from the stand point of evolution is that they can be turned on or off via other genes that apparently do nothing else but regulate the functionality of dna. These epigenes are a vital part of the evolution of species.
usfan said:One of the major rules of the scientific method is this:
'Correlation does not imply causation'.
If you make a claim of causation, you need evidence. Merely noting similarity in looks, or making assumptions about any correlation is not valid science.
And if that was what I was doing here, you might have a point. Since everything I have presented is backed by thousands of scientific papers written by thousands of scientists wrt countless field observations, experiments, and laboratory results, and since you have presented no evidence whatsoever to support any of your claims, I'd say that you are the one violating that principle.
usfan said:Claiming that there are all these genes that only need to be 'activated' is sci fi. There is no observable evidence that this is even possible, yet you assert it.
Welcome to the real world, pal.

usfan said:The assertion that animals create genetic material to adapt is fantasy. They do not. If an animal does not have the variability within it existing genetic code, it dies & goes extinct. THAT is what we observe, not the random creation of new adaptation traits.
We are what we eat. In this case, we are what the genome of the flora and fauna that live within us contain, genetically. Ever here of exogenous retroviruses? Horizontal gene transfer? These are all real, well documented phenomenon. But they are not what I was talking about. Read the article at the link above.
The correlation is always made, & i included the point. But if you want to leave it out, along with any implications from it, that is fine with me. Some people are more invested in abiogenesis, & insist on including it. I was mostly trying to cover my bases, & keep my ducks in a row.The biological theory of evolution does not, nor was it intended to explain the origin of life. It is only intended to explain the origin of species. If you want to discuss the origin of life, I suggest you start a new thread, because this one is about evolution.
What correlation, where? Perhaps you should pick another type of bird to keep in a row. I highly recommend Darwin's finches.
