It would behoove you to actually research transitional forms... if you did so you would realize there is more than idle speculation that stands behind the 'fad'... But if you want a quick little video to explain it to you... you should watch: http://youtube.com/watch?v=Qfoje7jVJpU It isn't so much idle speculation that I suggest, but more at presumptive interpretation, which should be conceded by true scientists. To me, it is understandable to assume the modern classifications seem reasonable. We seek to have a simple way to classify all of life which has such similarity in many respects; but justifying the classifications should be done with the appropriate levels of skepticism, which I never see in Nature articles or NOVA-type episodes. Granted I have read/seen very few of these overall, as I am not in the sciences; but the ones I have, seem conclusive and I can't tell how vetted are the assumptions in these pieces. I believe they are treated with appropriate levels of skepticism, although it doesn't always gets communicated after its processed and filtered by pop-science media for mass consumption on shows like NOVA, or general science articles in magazines and newspapers. quote:
BTW, it was Ken's presentation I saw somewhere that made the transitional argument between whales and dogs with 3 transitions (which he stated as sufficient evidence). Well whales didnt evolve into dogs or vice versa... without looking it up, I believe they are considered closely related with land animals like Hippo's.. I also think there are some organisms in the lineage that are somewhat reminiscent of canines, but not anything like we would think of today. Any chance you could locate this talk? I'm pretty sure the lineage of whales and other cetaceans has been pretty well established, with much more than 3 transitional forms. quote:
I watched your video; even pausing to read what I could in the opposing statements. It supported part of its argument by showing how much work paleontologists have done over the years. Throwing a myriad of fossil evidence at the theories out there does not prove our classification system. I am aware of the major arguments back and forth among the two groups regarding where the 'goal posts' should be to justify predictability of the theory. I am also aware of the fact that fossil evidence should be scarce compared to the vast amount of dead flora/fauna that has conceivably existed. But the video to me supports how both sides have different interpretations on this same evidence; the point of the video was to say that creationists only bring up facile arguments or move the predictability goalpost denying there is a lot of evidence collected. That may be, but despite their flaws at argument, I remain skeptical of the conclusiveness of the fossil record and the resulting classification system. I would disagree... the classification system (phylogenetic tree) is in no way arbitrary, or as ad hoc as the creationists would love for us to believe. The video does illustrate perfectly how evolution combined with the fossil record and the phylogenetic tree helps scientists make accurate predictions. It really illustrates the robustness of the system. Sure, we don't have all the info and sometimes also make wrong predictions, but nothing has seriously called the integrity of the classification system into question. It may have some errors, but it's a very sound system. Each side certainly has its own interpretations, and even science has got to be wrong on many points. The creationists are wrong on nearly all points, however.
