@blloydb,
Quote: Cladograms are part of the classification system used in evolutionary biology.
Borne out of evidence. Its like saying that a list of car models is put out by the manufacturer to sell cars. Well yeah,
A cladogram is a detailed biological/paleontological analysis in which affinities by structure and genetics(as possible ) , are constructed wrt the first appearance of a morphological feature in the fossil record. The theory is that a cladogram may not demonstrate the earliest appearance of a species , but it is certainly the latest. When all these forms so nicely fall into place by their emplacement, they form evidence that a species was derived in shape and time(unless you, like gungasnake believes that all science is merely a cabal of conspiracists whove gotten together to hide the truth). If you believe that way, you have to step back and objectively ask, "HOW AN HELL DID THESE ANIMALS FALL SO NICELY INTO PLACE WRT TIME?" If not by derivation from a central root stock that was a common set of ancestors
Nobody ever said that cladograms are proof. They merely suggest strongly that speciies have derived from common ancestors. Also, noone says that the fossil record is linear. However, when we UASE the information in the field to make predictions, WE HAVE NEVER BEEN WRONG IN THESE PREDICTIONS. Let some Creationist tell me how you find oil by wandering around Oklahoma and poking holes in the ground
Quote: Ok so life started as a base of a tree and branched off in different directions. ... It's that development I'm talking about - Darwin said it happened through natural selection, no intelligence or blue print involved, ... What I am asking for is proof. It seems you are unable to give corroborative evidence because the events happened so long ago. That's fine, but that means the assertion remains a theory, a supposition - even if it is an integral part, a building block, of evolutionary biology.
You are asking for proof for something that science has been laying out for about 150 years. There is no "proof" just strong evidence. Evidence is never sought without a mission. This is only good economics of how exploration sciences work. WHen Shubin and Daeschler wanted to see whether any intermediate fossils between bony fish and amphibian "fish" existed, they began looking by using a method of "falsification". They stated that, if intermediate fish/"opods" would exist in the ecord, they should be found in the rocks of the lower Devonian. SO they put their funding where their mouths were and spent 3 years searching the lower Devonian sections of SCotland/Greenland /and Nunivuit . They found such an intermediate fossil that filled in the "missing links between fish and amphibians". To a reasonable open minded layperson it would appear compelling "evidence" that the list of intermediate fossils was being added to. To a Creationist, it merely created two more "GAps".However , no matter what you accept as evidence or not, no evidence has been phonied up by scientists.\
Recently a fossil bird was found in China and was proposed to be a link between Eocene "mega" birds and later ratites. It turned out to be a phony . The phony was discovered by careful study by the NYMuseum oif NAt History. Now Creation "scientists" have been perpetrating fossil frauds for years, even Piltdown man is actuallyt a cover-up for "special Creation" thinking by Tielhard de Chardin and several others.
Additionaly, Several phony fossils of men and dinosaurs living together have been perped on the public by Creationsts. Also, the Cretaceous "human tracks" of the PAluxy River texas were found to be phonied up. However, No matter how much forensic evidence is produced to show that these are true fakes, the Creationists insist on using them as their own"proof". Now if you want science to engage in the same skullduggery as the Creationists, youd be waiting a long time. The rules of QA and QC require better practices be followed by science.
No matter , "proof" is different from evidence. Proof is for a math theorem, evidence supports a theory . Remember, the only way to prove a theory (like nat selection) is to Not Disprove it.
Also, thinking of the process of evolution as a tree is not really correct. In evolution, there is no trunk, only an initial filament. No base of a tree exists since any series of branches are no less (or more) important than any other. Genetic variability of species within a clade clearly show this. (Id really read a couple books by a guy who teaches at U Wisconsin, Sean Carroll-
DNA to Diversity, a later one
Making of the Fittest and most recently
Endless Forms Most Beautiful, these three , available in any University Library, discuss much of the overwhelming evidence that exists in extracting the sources for evolutionary journeys of species. He takes actual living examples , like forms of cave fish that are modified from species of free living fish in the same geographic areas as the caves, or "Ice Fish" which are evolved forms of sticklebacks that have developed an "antifreeze" system by exchanging this property for hemoglobin in their blood, as well as several morphological changes. These are but 2 examples of many tens of others he presents and your attempted arguments against evolution can be seen to be groundless.
Quote: So I take from this that species retain a lot of genes that then become dormant, and this is one of the causes of differentiation between species. How is it decided what is expressed or isn't expressed? Arbitrary? Random? Intelligence? No real proof really, just a supposition that its good ole natural selection (which has never been explained really). It remains some ethereal omniscient characteristic, kinda god like in a godless theory.
The "genius" of incremental change is that its not random at all. Once a (say adaptive)modification is made and a genic compliment (chosen from the variability built into the species makeup) is made, the genic structure for further modification is already there. IT DOESNT HAVE TO START FROM GROUND ZERO FOR EVERY SUCCESSIVE MODIFICATION> Now, you may ask what did the first genic compliment look like, I HAVE NO IDEA, noone does. All we can do is play a shaky mathematical game that compute s previous mutations and specified information therein. (Its actually a similar basis that the new computer evolution sym uses). Incremental variation only needs to be performed one step at a time with TIME as the big retort.
Im afraid that the proof you wish is not there. However, mountains of evidence is. If you merely dismiss the evidence and ignore its existence without exploring how compelling it is, this is not what wed want to see in a budding scientist. Its ok to have doubts and even strong feelings against. However, its up to you to want to honestly explore the range of evidence that supports AND refdutes any point. I can summarize probably 20 or so refutations of Creationism without breaking a sweat or looking anything up. I cannot, in all honesty discover ANY piece of evidence that supports evolution to be wanting. Gonna go back and watch the parade .
