(Horner explicitly renounced the pure scavenger theory in, among other places, an October 2009 interview on the outstanding Skeptics Guide to the Universe podcast)."<br /><br />My problem w/"the pure scavenger" hypothesis was that Horner continued to push it even after it had been falsified. Specifically, he said that there's "none whatsoever" (in reference to "evidence for hunting": http://dsc.discovery.com/guides/dinosaur/trex/feature/feature-05.html ) despite the existence of Carpenter 1998 ( http://www.mendeley.com/research/evidence-of-predatory-behavior-by-carnivorous-dinosaurs/ ).Hadiazhttps://www.blogger.com/profile/10805346627826158173noreply@blogger.comtag:blogger.com,1999:blog-140938929136406282.post-12777679098112018782012-01-22T21:35:02.948-05:002012-01-22T21:35:02.948-05:00"Proving a negative"
Falisification, afa..."Proving a negative"<br />Falisification, afaik, has nothing to do with not being able to prove a negative. Popper realized that Positivism Logical Empiricism was going nowhere and that inductively 'confirming' a position wasn't what science was really about. Therefore he promoted falisificationism and versimilitude (which Stephen Colbert calls "truthiness", in a way).<br /><br />"Honer's hypothesis regarding T. rex, now having been falsified"<br />But it hasn't been falsified. We have some counters to what we expect, but the thesis can be protected by modifications to our auxiliary assumptions. Its not 'simple' one-shot falsification that Popper and his student Lakatos were after. The Scavenger thesis requires, in light of evidence like tooth marks, changes in auxiliary assumptions about T. rex, which is acceptable. The question is, what do those modifications do to the whole Scavneger research program? Do they just try to brush away counter-evidence after counter-evidence, and thus the program degenerates, or do they lead to new, successful interpretations of collected observations, which would be quite positive.<br /><br />"so obviously CAPABLE of using logic and sound reasoning as The Newt"<br />What you have here is a demonstration that he is quite good a /rhetoric/. This is what nearly all politics used to be based on, in fact I dare say Gingrich considers himself a new Cato or some such, a skillful rhetorician who comes to power through debate.<br />I guess that would make Obama a Gracchi, Santorum a Phyrrus, Perry a (wanna-be) Pompey, and some would paint Ron Paul as a Cataline.<br />Woo Hoo, Ancient Romans and Dinosaurs in the same comment for the Win!Schenckhttps://www.blogger.com/profile/10802843636373254323noreply@blogger.comtag:blogger.com,1999:blog-140938929136406282.post-23297330434102767362012-01-22T19:26:28.549-05:002012-01-22T19:26:28.549-05:00I read on Facebook that it was Holtz who supplied ...I read on Facebook that it was Holtz who supplied Gingrich with the relevant info, so that explains something.Albertonykushttps://www.blogger.com/profile/00345306530772709064noreply@blogger.comtag:blogger.com,1999:blog-140938929136406282.post-58374577287120104322012-01-22T18:21:24.140-05:002012-01-22T18:21:24.140-05:00One thing to keep in mind: very often, *negatives*...One thing to keep in mind: very often, *negatives* can be expressed as positives.

I have never...Mickey give below most of my answer. <br />I have never assumed such bizarre estreme positions as "only scavenger" vs "killer-machine" like those who have seen as such these controversies. I don't want to reduce the paleontology to a physic-mimic Popperian world where falsification is the only discriminant between scientific hypothesis and unscientific ones. Is falsification the good method for paleontology? Popper himself said evolution cannot be falsified? That means evolution is not scientific? No, it means evolution is both a physic (Popperian) and storic (not-Popperian) science. Paleontology probably follows the same topic.<br />If the "falsification" model suggested for the ecology of Tyrannosaurus is the normal way paleontologists analyze fossil ecology, we should see its application more broadly in the field. Why it does not happen? Is Horner the only intelligent paleontologist around? He is a smart man (I've had the honor to meet him) but I don't think the rest of the paleontological community is blind in front of the way to look at dinosaur ecology.Andrea Cauhttps://www.blogger.com/profile/10855060597677361866noreply@blogger.comtag:blogger.com,1999:blog-140938929136406282.post-53165476015781200072012-01-22T11:50:25.556-05:002012-01-22T11:50:25.556-05:00To go along with this, I'd say that Honer'...To go along with this, I'd say that Honer's hypothesis regarding T. rex, now having been falsified, would by extension falsify the null hypothesis for all large theropods, due to the fact that Horner identified so many unique supposedly "obligate scavenger" characters that are now known to be present in an active predator. If T. rex was Horner's best example of a scavenging theropod, and we know it also took live prey, then all other known theropods, which are less well adapted to any hypothetical scavenging lifestyle, should also be assumed active predators. I'm not arguing we should not allow for parsimony, only that the initial assumption needs to be backed up with evidence, and then parsimony can be built from there, sort of like phylogenetic bracketing.Matt Martyniukhttps://www.blogger.com/profile/04220900229537564466noreply@blogger.comtag:blogger.com,1999:blog-140938929136406282.post-4736542490969704992012-01-22T11:34:16.443-05:002012-01-22T11:34:16.443-05:00I agree with Andrea.

Also, the idea you can't 'prove' a negative in science is flawed, as Richard Carrier explains here- http://www.infidels.org/library/modern/richard_carrier/theory.html . Indeed, paleontology is full of unprovable beliefs that are nonetheless justified until sufficient counterevidence is provided, and "all large terrestrial carnivores don't depend primarily on scavenging" is one of them. The alternative is throwing out entire fields like phylogenetics because they're based on assumptions that haven't been demonstrated to be true in every case.<br /><br />And here I thought the most substantive thing I'd be saying in reply was some joke about me agreeing with Newt. ;)Mickey Mortimerhttps://www.blogger.com/profile/08831823442911513851noreply@blogger.comtag:blogger.com,1999:blog-140938929136406282.post-33509499774050303842012-01-22T09:45:56.690-05:002012-01-22T09:45:56.690-05:00I don't think that's the right way to look...I don't think that's the right way to look at it. We shouldn't assume each individual carnivore is an obligate scavenger until that hypothesis is disproved, but we should also not assume the opposite. No assumptions of any kind should be making their way into the scientific literature if it's going to alter the results.Matt Martyniukhttps://www.blogger.com/profile/04220900229537564466noreply@blogger.comtag:blogger.com,1999:blog-140938929136406282.post-79123041690010013502012-01-22T09:33:20.449-05:002012-01-22T09:33:20.449-05:00Interesting episode.

Is paleontology a phylosopy or a science?<br />Creationists and BANDists often cite falsificationism as a weapon against what they are unable to fight with the evidence.<br />And I hope we all stop talking about that hypothesis as like it was one of the most important problem in paleontology (as it seems looking at how often it's mentioned in every media). Why nobody discuss the hypothesis that Carnotaurus was only scavenger? Or Giganotosaurus, or Spinosaurus, or Dilophosaurus, or Smilodon, or Anomalocaris, or Homo neandertalensis? <br />If that hypothesis is more scientific than its opponent just because it's can be falsified, why do paleontologists don't use it for every animal?Andrea Cauhttps://www.blogger.com/profile/10855060597677361866noreply@blogger.com
