@Leadfoot,
Nor am I convinced thst DKS is a 'sufficient basis for the life process' in that it counters the second law of thermodynamics. Both quantum effects, and field effects may contribute to the issue. But nothing can 'prove' ID, in the sense that nothing, even in science (which ID blatantly is not) proves anything ! All science can give is a network of working hypotheses and concepts aimed at prediction and control of human concerns, forever subject to revision as what we call 'knowledge' evolves. Indeed ID can be considered a hindrance to epistemological progress as it is no more than a dressed up version of 'the 'Tree of Knowledge' story whose 'moral' has theistic rather than practical significance.

@izzythepush,
Could it be they were classified wrong. A great Dane and a Chihuahua might be considered different species if those were the only two dogs you had to compare. They are cats bears and horses.

BIOLOGY
a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. The species is the principal natural taxonomic unit, ranking below a genus and denoted by a Latin binomial, e.g., Homo sapiens.
By that definition, they are one species.
Quote:
Species
From Wikipedia, the free encyclopedia
For other uses, see Species (disambiguation).

The hierarchy of biological classification's eight major taxonomic ranks. A genus contains one or more species. Intermediate minor rankings are not shown.
In biology, a species (abbreviated sp., with the plural form species abbreviated spp.) is the basic unit of biological classification and a taxonomic rank. A species is often defined as the largest group of organisms in which two individuals can produce fertile offspring, typically by sexual reproduction. While this definition is often adequate, looked at more closely it is problematic. For example, with hybridisation, in a species complex of hundreds of similar microspecies, or in a ring species, the boundaries between closely related species become unclear. Other ways of defining species include similarity of DNA, morphology, or ecological niche.

All species are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes in zoological nomenclature). For example, Boa constrictor is one of four species of the Boa genus.
In the end, it is irrelevant to the discussion on whether random mutations can provide the new information in the correct way to cause macroevolution through natural selection.

The point is that a recombination of two different genomes leads to new text. Imagine that an editor mixes by mistake two tragedies from Shakespeare: one verse from Macbeth, one verse from the Midsummer Night Dream, etc. Among much bizarre jibberish, one could perhaps find an interesting quatrain or two.
Yes but the overall result is bizarre gibberish. For the two to be comparable we would have to end up with a new more complex Shakespearean tragedy. Without intelligence intervening you end up with a story that is gibberish, and an animal with a cancerous growth that look something like a complex organ and even be passed on for generations but, it will not turn into a new organ system without intelligence. If it a computer program should be able to be written into a word processor that creates new and improved Shakespearean tragedies by randomly regrouping words, and then turning each edition in for printing and saving only the ones that sell in the market. Do you think we can write a program to do that?

Of course ID is simplistic. It's easy to replicate, and with enough intelligence, it always works. According to occam's razor it wins be default. But I will read what you suggest.

Is it science to discuss the evidence of who designed the first automobile, the first wagon, the first wheel and axle? Maybe the first wheel and axle was designed by a chimp but, I doubt it. You don't see chimps building wagons, even if one did figure out how to make ma wheel and axle he didn't hand the knowledge down to future generations. Because, there is no evidence of it. Is that an unscientific statement?

Ah, more dismissal out of hand. I was speaking in hyperbole in that final sentence but I don't suppose it would have made any difference if I'd said evidence instead of 'proof'.

ID is simply an hypothesis. Any hypothesis whether true or not can be looked at scientifically. For example, You could validly do a scientific study of astrology. Doesn't mean it's true and you might conclude it is false but it in no way invalidates the study undertaken to determine that.

Saying that ID cannot be scientifically studied is nonsense. That would be a denial of science itself.

No. The 'denial of science' is entirely yours.
Since ID is not 'falsifiable in principle' it is not 'scientific' by definition. (I thought we'd been through this before...Popper's falsifiability principle). Even if 'life' were created by a scientist in a laboratory ID-ers could claim this was merely 'life begetting life', and if 'life'was observed to apparently arise 'spontaneously' ID-ers could claim that it was 'a divine act'.
Religion in general and ID in particular no longer have anything to contribute to what are called 'scientific questions'.

It is. It would also be "science" to discuss and to investigate for similar evidence for ID. So far, Im not aware of ANY, (and I try to keep an eye peeled for current literature.

you said it. Its approximately the same way that life has progressed through time. The fossil record provides us with many examples ( aka "fossil species") of so many of these variants in a single genus that we can see adaptive pressure imposed by the environment for (eg) trilobites to conform to the changing condition of the water nd sediment load.

You seem to be fixed on one song nd dont see any other aspects of the piles of data, such as biogeographic adaption nd speciation, convergence(hint hint), "red Queen", winnowing nd EXTINCTION of the many; adaptive radition nd the "Baldwin Effect"; uses of same genes to accomplish different phenotypic expressions and thus, species diversity,(eg PAX-6),"stop triplet nucleotides" that can turn off/on proteins like SWS opsins (which control vision sensitivity and color ranges for many different species), the "tool box" of Long and short interspersed elements which allow scientists to "Track" common ancestry;gene flow and genetic drift.

All reference to the second law of thermodynamics in regard to the earth within the solar system are idiotic on the face of it. That axiom--that total entropy can only increase over time for an isolated system, meaning a system which neither energy nor matter can enter or leave--is meaningless with regard to life on this planet. This is not a closed system. It is very likely that precious little new matter will be added to this planet--the Chicxulub event may have been the last major hit on the planet; but new energy enters the system every day from our star. The god-botherers love to trot that one out, it's a shame to see a supposedly intelligent, well-educated individual bring it out. Until Sol grows old, billions of years from now, and expands to irrevocably scorch the Earth, we are in an energetic system to which energy is added every second.

Yes, we have. Your assertion is just a denial. If I have to spell it out for you, ID will be falsified as soon as a reproducible example of abiogenesis comes out of the lab. Until then, ID is just as plausible an hypothesis as 'natural' abiogenesis.

Oh wait, are you saying that could never happen?

@Leadfoot,
ID has already been falsified. The bible claims this earth is 7,000 years old. Science shows us that this planet is 4.5 billion years old.

Your creator doesn't exist (no evidence), so how can your creator create anything? A creator who can't be proven to have created this planet is absurd. It goes nowhere.

This is evidence that natural selection works. Natural selection does not create new information for the DNA to work with. Random mutations do.

per and multiple books that random mutations are the only driver for new information for natural selection to use, I just agree with one the best. We need to concentrate on how random mutations can provide such complex information by random generation of new information. Wiki says,

the Red Queen effect, is an evolutionary hypothesis which proposes that organisms must constantly adapt, evolve, and proliferate not merely to gain reproductive advantage, but also simply to survive while pitted against ever-evolving opposing organisms in an ever-changing environment. The hypothesis intends to explain two different phenomena: the constant extinction rates as observed in the paleontological record caused by co-evolution between competing species,[1] and the advantage of sexual reproduction (as opposed to asexual reproduction) at the level of individuals.[2]


The red queen effect has nothing to do with generating new information for the DNA, it is just a more detailed description of natural selection.

"Baldwin Effect"; uses of same genes to accomplish different phenotypic expressions and thus, species diversity


Wiki says
Quote:
Selected offspring would tend to have an increased capacity for learning new skills rather than being confined to genetically coded, relatively fixed abilities. In effect, it places emphasis on the fact that the sustained behavior of a species or group can shape the evolution of that species. The "Baldwin effect" is better understood in evolutionary developmental biology literature as a scenario in which a character or trait change occurring in an organism as a result of its interaction with its environment becomes gradually assimilated into its developmental genetic or epigenetic repertoire (Simpson, 1953; Newman, 2002). In the words of Daniel Dennett,[2]


The Baldwin effect argues that learned behavior can be passed on genetically and guide evolution. Learned behavior is intelligence. Baldwin assumed that this intelligence gradually assimilated into its developmental genetic or epigenetic repertoire. That by definition is intelligence introducing new information into the DNA code, or an argument for ID. (but is not an argument for a God of the bible, but a more organic intelligence in nature) This still only guides random mutations, and is hardly the answer for how in the heck did random mutations provide the complex information so consistently.

Quote:
Paired box protein Pax-6, also known as aniridia type II protein (AN2) or oculorhombin, is a protein that in humans is encoded by the PAX6 gene.[5] Pax6 is a transcription factor present during embryonic development.

In molecular biology, a transcription factor (TF) (or sequence-specific DNA-binding factor) is a protein that controls the rate of transcription of genetic information from DNA to messenger RNA, by binding to a specific DNA sequence.[1][2] Their function is to regulate - turn on and off - genes in order to make sure that they are expressed in the right cell at the right time and in the right amount throughout the life of the cell and the organism. Groups of TF's function in a coordinated fashion to direct cell division, cell growth, and cell death throughout life; cell migration and organization (body plan) during embryonic development; and intermittently in response to signals from outside the cell, such as a hormone. There are up to 2600 TFs in the human genome.

TFs work alone or with other proteins in a complex, by promoting (as an activator), or blocking (as a repressor) the recruitment of RNA polymerase (the enzyme that performs the transcription of genetic information from DNA to RNA) to specific genes.[3][4][5]


PAX 6 is an amazing protien, that makes sure the right type of cell is growing in the right place at the right time in an embryo. We kind of understand what it does and kind of understand how it works.

Role in evolution[edit]
Further information: Evolutionary developmental biology
Gene duplications have played a crucial role in the evolution of species. This applies particularly to transcription factors. Once they occur as duplicates, accumulated mutations encoding for one copy can take place without negatively affecting the regulation of downstream targets. However, changes of the DNA binding specificities of the single-copy LEAFY transcription factor, which occurs in most land plants, have recently been elucidated.
(LEAFY (abbreviated LFY) is a plant gene that causes groups of undifferentiated cells called meristems to develop into flowers instead of leaves with associated shoots.)[1] In that respect, a single-copy transcription factor can undergo a change of specificity through a promiscuous intermediate without losing function. Similar mechanisms have been proposed in the context of all alternative phylogenetic hypotheses, and the role of transcription factors in the evolution of all species.[74][75]
Basically this where the rubber meets the road. These transcription factors is probably where the new information is entering the DNA, for evolution. These proteins guide the cell growth of vast number of cell types, that reproduce very complex organisms, and do it new near perfection. They are carrying an extremely complex code that reacts differently in different situations, and maybe even in different environments. I don't know if we can tell if new information is being introduced by the arrangement of these proteins randomly or, was encoded in the DNA at a much earlier and more primitive era in expectation of planned future environmental conditions. In the end Nei is right. These protiens have nothing to do with natural selection, and a random process is necessary to introduce new information that created these protiens at the beginning stages of evolution or is introducing the new information into them as evolution progresses. I believe that is asking random processes to provide more complexity than can be reasonably done. Anyone stating or implying that the genetic code is being guided or reacting to the environment through natural selection which leads to macroevolution, is implying there is a built in intelligence in nature, and is refusing to identify it as ID because of philosophical biases. How the information is transferred across these proteins is the next frontier of biogentics. https://www.academia.edu/7363559/Quantum_biology

I suggest you do quite a bit more study about this gene protein alone.With an understanding beyond a Wiki clip you will learn its involvement in differentiation among various higher taxa eyes(like compund eyes of a fruit fly, the compound eye of a horseshoe crab. Also its one of a series of "toolkit proteins" which are responsible for physiology and form The toolkit proteins (others to follow) are devoted to making the form of various tissues and organs and appendages of an organisms phenotype. These proteins actually control (or indirectly affect) where and when that genes are used in the body.
Pax-6, has many other jobs in building the body and body parts. PAX-6 is also involved in nasal structure in ll mammals .
Your concern about mutations alone, needs to be tempered with realizing that a single mutation in,say, the opsin protein effects the spectrum of light thats detected by the rods or cones of the organisms eye. Therefore, ONE MUTATION can lead the way to adaptive radiation between the descendants of a "Common ancestor" of daughter species that will be adapted to day or night life. The opsin mutations provide a dogs breakfst of different phenotypes with those opsin configurations and perhaps a few will survive. This isTransposable genes AND natural selection . Also, post transposition of the PAX-6 opsin, the same protein will direct other mutations via a number of chemical foldings, linkages, transpositions, editing, or omission via inserting a stop codon into the gene
Darwin said (bout the making of complexity , or speciation)
"When we regard every production of nature as one that HAD A HISTORY; when we contemplate every complex structure and instinct as the summing up of many of these contrivances, each usable to the possessor... ho far more interesting will the study of natural-history become".

His use of "contrivance was not a tip of the hat to ID, but a smackass at William Paley who first coined the term when he considered life as the same as wrist watch found in th scrub plains of Scotlnd in 1802.

@brianjakub,
Nei is certainly entitled to his opinions but its fairly obvious that (even by the neutral "theorists") selection occurs at all levels, cellular to organismal and is accomplished as a physiological "tropism" by mostly external agents.
Ascribing "ID" to given chemical reactions is kinda lame thinking on ID's behalf. I know they are merely trying to insert a deity in the mix but they seem to deny that Oxidation/Reduction is intelligence-free to make it happen, further dont ALL surface reactions happen blindly in nature whether its just mere adsorption, hydrolysis, linkages or a whole bag of reactions. Why do they need some overseer?? (I really think the MAGIC occurred over 10 billion years ago when , after the Big Bang, which only created Hydrogen and helium, how the heavy elements got produced)

Youre still obviously flopping around looking for a landing .I can see youve not read any of the Sean Carroll book that I suggested to you several months back (Making of the Fittest). Otherwise youd have seen my clip of my early ridiculing of the Biochemistry of ID. I think I also told Leadfoot and I believe he actually caught up with it.
Evolution , on the whole, is an interaction of mutation (not redesign from scratch), natural selection, and Time. ID "hypothesists" scramble about by trying to dispute and deny one of these components. The overall evidence, like Dr Behes writings and testimony on "Irreducible Complexity" stand in evidence totally against His writings. (Still, he is a featured scholar and a board member of the Discovery Institute the USA center of science denial on evolution by nat selection).

@Leadfoot,
You don't get it do you !
Natural abiogenesis IS likely to be 'understood' given advances in systems chemistry and quantum theory etc, and synthetic abiogenesis IS a subsequent possibility. But even in that event, theists will argue that the 'creativity' involved was 'in the gift of the deity for his own purposes'. After all, we already have some theists acknowleging evolution as part of ' His purpose' ! You underestimate both the nature of epistemological progress and the reaction of vested interest theists in countering it.

The ultimate fallback position for hard line theists is the question 'why is there something rather than nothing ?' But even that question is open to potential philosophical deconstruction.

But you won't 'get it' will you ? Too much at stake! It's much easier to play 'no it ain't/tis so' games with the current human concepts of 'science' and 'abiogenesis' isn't it ? Wink
