No worries. Forum being a nuisance is not your faultNaraoia I apologise, but your post still did not load.
Evolutionary biology degree, enduring love affair with fossils and evo-devoYou appear to be educated,
To be precise, I know several different definitions of macroevolution.Surely you know what macroevolution is, yet you have posed the question to me.
Adaptation =/= microevolution. Microevolution is simply evolutionary change within a species. It could be adaptive, or it could be neutral. (I guess it could also be maladaptive, say deleterious alleles getting fixed in a population bottleneck)What evolutionists have observed is adaptation, or microevolution.
New species names are given for various things, new adaptations being only one of the possibilities. Sometimes, they are proposed simply because genetic evidence indicates that two or more populations haven't interbred in a long time. (Giraffes come to mind.)These new adaptations are given a new species name.
Some certainly do, but whether macro = lots of micro is actually a debated issue. There are several respected figures who don't take that assumption for granted at all. Here's a book chapter discussing the question, and here's a recent paper.Scientists ASSUME that many microevolutions will turn some creature into a cat and a dog, two different kinds.
Excuse me? One of the central ideas of cladistics is that taxa should only be grouped together based on shared derived traits. There is no such thing as a "derived" trait without evolution.You also request a definition of kind. A kind is akin to a family group. You will be aware of the use of cladistics these days which basically is a creationists idea.
Careful with the discontinuity line. Cause it doesnt work. (Also, hardly a week passes without a research paper that finds a form of this or that oh-so-sophisticated human ability in other animals. Our good old superiority complex doesnt seem like a very scientific stance these days.)Kind is defined by using discontinuity and baramins. Discontinuity demonstrates that humans have sophisticated speech and higher reasoning ability. Therefore those creatures without these traits are discontinuous with mankind.
It does not. First, there is nothing in evolutionary theory to require a single common ancestor. (I think that was a subject of a recent debate over Douglas Theobalds Nature paper: do bacteria and the rest of life actually represent independent origins, and can we determine if they do?)Under the evolutionary scenario there will be a consistent pattern of similarity forming a nested hierarchical structure stretching as far back as the phylogeny can be resolved (and ultimately as far back as the Last Universal Common Ancestor). Under the creationist scenario, on the other hand, the pattern of similarity would only be expected to stretch back as far as the point of the independent creation of kinds. There is no reason to expect there to be any consistent phylogenetic resolution beyond this point.
Thus we have a specific creationist prediction that can be tested - that molecular comparison studies will only obtain a consistent phylogenetic tree as far back as the point of creation, beyond which there will be no further resolvable pattern. As this directly contradicts the evolutionary prediction this provides a definitive means of determining which of the two scenarios is correct.
Im not sure how the existence of HGT refutes evidence for common descent where levels of HGT are low. Unless you want to argue that the created kinds are on the level of kingdoms or above (e.g. animals dont engage in all that much HGT, except with viruses), this isnt going to help you.We now know that LUCA is dead, with HGT. So there goes one irrefuteable evidence for evolution and common descent.
The old you werent there argument? Come on, you can do better than that. And while molecular phylogenetics may not be able to touch non-avian dinosaurs, we do know where Neandertals and mammoths belong. Surprisingly enough, pretty much where their bare bones put them.You also have no DNA from creatures millions of years old, so even evolutionists can only guess where extinct and debated species belong, especially given that most of them are single bones or fragments.
For the same reason I requested a definition of macroevolution. Seriously.You request a definition of major change..seriously!!!
I cant dispute that, and I recall that a large part of the Podarcis phenomenon was phenotypic plasticity. The problem is that (1) there are things you can only get from genetic innovation (most obviously, new genes...), and (2) there are novelties that are known beyond reasonable doubt to result from genetic innovation (nylonases, insect abdomens)Major may be seen in the development of a cecal valve in lizards due to a change in diet. This was a somatic change but quite remarkable and major. Hence major phenotype change is not tied to Mendellian inheritance.
Lizards Undergo Rapid Evolution After Introduction To A New Home
I wasnt defending Darwin, I was criticising your (mis)use of Darwinian.You may defend Darwin as much as you wish Evos and creationists alike generally know he was simplistic and got alot of things wrong.
Now what did I do to deserve that?Do you? or would you like it spelled out as well.
Which was a while ago, wasnt it?Who said Mendellian inheritance was the only way to evolve? Oh just EVERYBODY untill HGT and endogenisation was found..........
What the heck does this have to do with the fact that bar-headed geeses adaptation to high altitudes involved GENETIC changes?As for your goose link. Modern bird footprints were dated to 212myo that evos have had to make up all sorts of non plausible scenarios about to justify, like bird-like dinos with modern bird feet.
That many would be about... Alan Feduccia, John Ruben and Larry Martin. I may have missed a few, but they are a drop in the ocean. And Ive seen the second of those... erm... quoted to say things about a paper of his that werent exactly true in a press release (said paper is absolutely shredded by Darren Naish here). As for the tracks: I dont know what to say about their birdness, since I dont know much about dinosaur/bird feet. I'll pass on this one. (Where are the vertebrate palaeontologists when I need them?)I know, I know, homology and homoplasy explains it all, do you think? However really, what these bird footprints demonstrate is that your researchers have little clue what they are on about in relation to birds. These days many researchers are challenging the dino to bird thing anyway.
I never understood this. The BANDits dont dispute that birds are a product of evolution, they just disagree about who their ancestors were and when they arose (and most people in the field dont think they have much of a case). In fact, theres a hypothesis that Archie and other maniraptorans descended from birds, not the other way round (Naish also discusses this at length). How does an alternative evolutionary hypothesis suddenly become an argument against evolution?So there goes evolutionary phylogeny and nested hierarchies because modern birds were here heaps before archaeopteryx.
So now they were only created 300, not 360 million years after fish?According to a creationists interpretation of the data and fossil evidence, these bird footprints are modern bird footprints that place birds closer than ever to the biblical account of being created after fish. They were thriving 212mya.
Phil Senter disagrees. Using creationist methods, no less.There is no intermediate between a bird and another kind, such as a dinosaur. This is a creationist prediction that is being continually verified with increasing data.
Sorry? Did you just say that science should not evolve in response to data?This is science rather than the ever changing face of evolutionary thinking that evolves in response to data rather than the data continually confirming prior thinking.
(1) OK, then, tell me about the function of Alu elements. Or heck, the two hundred thousand or what human endogenous retroviruses that arent active and did not give us syncytin... (2) How is a lack of junk DNA incompatible with evolution? There are various ways to falsify the ToE, but this is not one of them as far as I'm aware.Another creationist prediction is that there will be no junk DNA. Even before the discovery of function for non coding dna, creationists never back flipped by saying 'oh well maybe God did make some junk stuff after all'. No, we have stuck to our prediction and we continue to be vindicated as time goes on.
and genetic drift and HGT and developmental bias and... Friendly advice: dont ever equate evolution with natural selection if you want to sound like you understand it.Do not forget that evolution, ie natural selection,
What vital function do dead retroviruses provide?... has now been seen to act on new stuff, like supposed virus-LIKE remnants and ghosts that comprise 8% of the genome, horizontally transferred, endogenized and also providing vital function.
Good to see youre up to date on evolutionary theory...Now you have epigentic inheritance that demonstrates that mutations and natural selection is not all there is to it. In fact I feel the veracity of any of your genomic research has fallen through the floor. The simplistic assumption that genes offer up a smorgasboard of traits that natural selction acts upon is now questionable!
This is why people in the phylogenetics business always always always consider multiple characters, avoid superficial similarities (e.g. "insects and birds have wings") and try to exclude ones that are known to be prone to convergence. E.g. we know from thousands of years of animal breeding experience that things like the length of limbs evolve easily in response to selection. It would be pretty stupid to use "long legs" as a character to unite greyhounds and horses to the exclusion of dachshunds. Similarly, it's not wise to use simple amino acid repeats to group together two proteins, because we know that short tandem repeats evolve easily by slippage during DNA replication.Naraoia
Creatures such as the marsupial mouse and the eutherian mouse look very similar, but they differ a great deal in their genetics and biochemistry.
It appears to me that evolutionists choose the traits, either genetic or morphological, apply that choice and then offer this up as evidence for evolution.
Anyone can CHOOSE their criteria, apply it, and get the results they want.
What you talked about here is actually a different problem from the previous one. All non-human primates fall outside the group of mankind anyway. These traits you list only change where you draw various boxes on the same family tree. E.g. if your criterion for being "human" is sophisticated language, then maybe only one species is "human". If it's "habitual or obligate bipedalism", then australopiths are also human. However, summing over many characters, we still have, say, Neandertals as our closest relatives, H. erectus a little farther, and australopiths still farther away. The only thing that changes is what you call each branch.If I choose the creation of the variations of FOXP2 gene as a criterion, then only the creatures with the human version of the foxp2 gene will lob into the same hierarchy. If I choose sophisticated language likewise I can group mankind together. If I choose leg to hip joints likewise, erectus falls outside the group of mankind. If I choose the difference between a fur coat and the shorter hair on the human boby as a criterion, likewise all non human primates fall outside the group of mankind. It is arbitrary and a matter of the criteria one chooses to use. The criteria is a choice and is unfalsifiable, both for evolutionists and creationists alike.
we know from thousands of years of animal breeding experience that things like the length of limbs evolve easily in response to selection.
How ironic that Darwinists ignored Mendelian inheritance for forty years. The real science languished on the shelf while Darwin enjoyed the scientific spotlight. Hybridization is not evolution You are still making that same mistake.
I am someone who prefers the empirical evidence over speculative nonsense. Evolution is a chameleon able to change its strips as its suits. As soon as real objections are put forth there is always some magic thrown in to push the debate down the road. Real problems like the origin of life have never been explained by evolutionist. Oh yes Evolution once tried to explain the origin of life.

I'm sorry, but what the heck are you talking about? Do you know what hybridisation or evolution is, in the first place?we know from thousands of years of animal breeding experience that things like the length of limbs evolve easily in response to selection.
How ironic that Darwinists ignored Mendelian inheritance for forty years. The real science languished on the shelf while Darwin enjoyed the scientific spotlight. Hybridization is not evolution You are still making that same mistake.
Translate: as soon as ignorant objections are raised, the people who actually understand evolution always dig out something you never thought of that completely demolishes the objection.I am someone who prefers the empirical evidence over speculative nonsense. Evolution is a chameleon able to change its strips as its suits. As soon as real objections are put forth there is always some magic thrown in to push the debate down the road.
Life could have originated by spontaneous generation for all it matters to evolutionary theory. The fact remains that imperfect replicators inevitably evolve, and all life is related.Real problems like the origin of life have never been explained by evolutionist. Oh yes Evolution once tried to explain the origin of life.
Huh?? What fact am I suppose to recognise? That after a good long while, someone finally realised that genetics and evolution get along just fine?That is what is wrong with the new synthesis; evolution did grok the entire theory of Mendelian genetics and claimed it as its own. Of course if you recognized that fact it might put a bit of tarnish on that golden statue of Darwin maybe it is not real gold.
"The synthesis, produced between 1936 and 1947, reflects the current consensus.
Yeah, I thought I said the same thing. What is the problem again?The previous development ofpopulation genetics, between 1918 and 1932, was a stimulus, as it showed that Mendelian genetics was consistent with natural selection and gradual evolution. The synthesis is still, to a large extent, the current paradigm in evolutionary biology."
From the Wiki.
Aaaaaand your point is? Are you somehow under the impression that I... worship Charles Darwin?Mendelian genetics was not accepted science for over forty years; Mendel died without any recognition and was only posthumously recognized as the founder of modern genetics. Evolution dogma had a great deal to do with that besides ignoring Edward Blyths contribution to Natural Selection (before Darwin).
Interruptions are fine. Irrelevant interruptions can get a bit annoying.Sorry I did not mean to interrupt
Whatever does that mean?Spontaneous generation please take that up to your own shame.
I didn't spell it wrong, I spelled it British. Welcome to the world beyond the USA.By the way I think you spelled humoured wrong humored
Um... at school?Wow where did you learn English in Hungary?
Usage notes
That was not the word I used, though I said I humoured someone (verb), not that something was humourous (adjective that even I wouldn't spell like that).§ Nowadays, this spelling is much less common than humorous, even in regions where the spelling humour is overwhelmingly preferred.
I wouldn't have to play obtuse if you didn't respond to me with cryptic remarks that sound a lot like insults.Naraoia

Trying this again...
I think we see a lot of debates about evolution in here, but not many threads scrutinizing creation in the same way.
I'd like to try something here. This thread is going to be a one on one, which means the first creationist (using the standard definition, if you don't know what I'm talking about, don't worry about it) who pops in here to state their case will be the one that I talk to. Everyone else can talk in non-participant commentaries, I don't want this thread getting cluttered.
Here is the conversation. You as the creationist state a case for creationism and/or intelligent design, I will argue against it. Both of us will stay away from talking about evolution as much as possible. For the purposes of this conversation, if your argument for creation is a criticism of evolution, it will not be considered valid, likewise if my argument against creation is an argument for evolution, it will not be considered valid. I want to keep evolution out of this as much as possible. I don't know how successful this will be, but I just want to try something new.
For the record, while it certainly isn't prohibited, I will not be very receptive to evidence given from holy texts, please keep that in mind.
So again, if you are not a creationist or come in after one has already posted, kindly defer to non-participent commentaries, otherwise fire away, I'm listening.
I say it is fruitless to debate evolutionists as they often are unable to differentiate the evidence/data from the scenario or interpretation of the evidence...so there is no point even trying.
I would love to see you attack them successfully first (What is "PIW", anyway?)Naraoia...
Take it up in an argument for the affirmative
(PIW) and (RNA world view) are ridiculous. I would just love to see you defend them successfully.. Take it up as a challenge.
