This is a multi-part message in MIME format. --Boundary_(ID_U1ZqNzsvsUS89aUclndMwQ) Content-type: text/plain; charset="iso-8859-1" Content-transfer-encoding: quoted-printable My disagreements with "Qilongia" Now, really, why don't you use his name? Another censored critic against "Qilongia" is a brilliant paleoartist = and student of dinosaurology, who maintains an excellent website re: = archosaurs at <www.dinohunter.info>), who is, for similar reasons, also = not a part of the forum in question. Yes, he is a brilliant paleoartist. Yes, he is a good scientist. In = spite of this he has, AFAIK, unsubscribed from the DML after having been = timed out a few times because he interpreted very much as personal = attacks, got enraged and flamed back even though nobody had flamed forth = -- an unfortunate circumstance which made some discussions pretty = tiring. I think Therizinosaurus to be barely diagnosable as a theropod based = on the original hypodigm, and can be reasonably interpreted as a nomen = dubium, Why? And why "as a theropod"? Those meter-long claws are unlike anything = else on Earth =3D diagnostic. it being only later specimens of other taxa allowing a clearer picture = of "therizinosaurs" to emerge. Yes, of the whole group, of the relationships of Therizinosaurus = cheloniformis. But being incertae sedis is not the same as being a nomen = dubium. What do I miss? While I am at it, back to the topic: I think that, under PhyloCode, = there should be a clade Therizinosaurus but no species cheloniformis M A = /\ E E B , 1954, because we still don't have anything near a = population-sized sample of it; every paleontologist will be able to = think of similar examples. As Schiller said: Mit Dummheit kamepfen die Goetter sebst selbst = vergebens.=20 For those here who are scientists but not scholars: "Even the gods = themselves fight with stupidity to no avail." (Original without typos = and without the ae, oe, ue transcription for =E4, =F6, =FC: Mit Dummheit = k=E4mpfen die G=F6tter selbst vergebens.) However, I fail to see = stupidity in this discussion... Geodynamic perfection in an organismic sandbox Pardon? reducing discussions of phylogenetic systematics to the level of a = "reality show". Well, then consider yourself lucky you've apparently never seen a = "reality show"! :-) Also please keep in mind that most subscribers to = the DML are neither scientists nor scholars (let alone both*), so = they'll inevitably ask questions that have been answered inside the = ivory tower decades ago. * As I understand it, a scholar is a learned person (all the same in = German: Gelehrte/r) who knows the literature but does not necessarily do = science, e. g. a theologian can be a scholar but not a scientist as = there are no testable hypotheses in theology. But since the term has = become rare early last century, maybe this usage is different from other = people's. Unfortunately, "Qilongia" conflates interpretations of processes = re: hybridization and speciation as avenues of speciation, and do not = merit re-analysis. What does not merit re-analysis? And why didn't you simply post your = corrections to the DML? we say that combined characters (synapomorphies, etc.), within an = individual, are the basis of "species fitness", viz. species selection. Assuming species selection exists. Er... but what does that have to do = with the statement "a hybrid can't be a species" (made by a complete = layman), with which this discussion began? (In the event that "Qilongia" has access to libraries with journals, Unlikely. I mean, not "with journals", but "with a large number of = interesting journals". I could lament for hours on the pretty big = geosciences library of Vienna University. Allow me to use this outline (borrowed from the above writers; > = here meaning affect): emergent species-level traits > species-level = fitness (E.

All of this hinges = on how, when completed in greater degree, the PhyloCode interprets = "species". But, probably, not the other way around, so I think we can treat the = latter problem in isolation from the former. Which is relatively futile = before a certain important paper will be published. Setting aside the "therizinosaurs", we can consider dinosaur species, = e.g., as "uninomials", and relationships among species are taxonomic = "addresses" (to borrow from the important 1999 by Phil Cantino & team). = The Linnaean system, of course, is no longer viable in phylogenetic = discourse. We can say, thus, that Tyrannosaurus + rex indicates a least = inclusive clade (the "genus"), of which rex species is an uninomial = part. In short, do you favor method M or something similar? :-) It will be the course of development, of course, that the = "therizinosaurs" will be thoroughly redefined, th Yes? --Boundary_(ID_U1ZqNzsvsUS89aUclndMwQ) Content-type: text/html; charset="iso-8859-1" Content-transfer-encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META content=3D"text/html; charset=3Diso-8859-1" = http-equiv=3DContent-Type> <META content=3D"MSHTML 5.00.2920.0" name=3DGENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=3D#ffffff> <BLOCKQUOTE=20 style=3D"BORDER-LEFT: #000000 2px solid; MARGIN-LEFT: 5px; MARGIN-RIGHT: = 0px; PADDING-LEFT: 5px; PADDING-RIGHT: 0px"> <DIV><FONT face=3Darial,helvetica><FONT face=3D"Times New Roman" = lang=3D0 size=3D3=20 FAMILY=3D"SERIF"><B> My disagreements = with=20 "Qilongia"</B></FONT></FONT></DIV></BLOCKQUOTE> <DIV><FONT face=3DArial lang=3D0 size=3D2 FAMILY=3D"SERIF">Now, really, = why don't you=20 use his name?</FONT></DIV> <BLOCKQUOTE=20 style=3D"BORDER-LEFT: #000000 2px solid; MARGIN-LEFT: 5px; MARGIN-RIGHT: = 0px; PADDING-LEFT: 5px; PADDING-RIGHT: 0px"> <DIV><FONT face=3Darial,helvetica><FONT face=3D"Times New Roman" = lang=3D0 size=3D3=20 FAMILY=3D"SERIF"><B>Another censored critic against "Qilongia" is a = brilliant=20 paleoartist and student of dinosaurology, who maintains an excellent = website=20 re: archosaurs at <www.dinohunter.info>), who is, for = similar=20 reasons, also not a part of the forum in=20 question.</B></FONT></FONT></DIV></BLOCKQUOTE> <DIV><FONT face=3DArial lang=3D0 size=3D2 FAMILY=3D"SERIF">Yes, he is a = brilliant=20 paleoartist.
