A university professor said she was asked to resign for introducing elite students to flaws in Darwinian thought, and she now says academic freedom at her school is just a charade.
During a recent honors forum at Mississippi University for Women (MUW), Dr. Nancy Bryson gave a presentation titled "Critical Thinking on Evolution" -- which covered alternate views to evolution such as intelligent design. Bryson said that following the presentation, a senior professor of biology told her she was unqualified and not a professional biologist, and said her presentation was "religion masquerading as science."
The next day, Vice President of Academic Affairs, Dr. Vagn Hansen asked Bryson to resign from her position as head of the school's Division of Science and Mathematics.
"The academy is all about free thought and academic freedom. He hadn't even heard my talk," Bryson told American Family Radio News. "[W]ithout knowing anything about my talk, he makes that decision. I think it's just really an outrage."
Bryson believes she was punished for challenging evolutionary thought and said she hopes her dismissal will smooth the way for more campus debate on the theory of evolution. University counsel Perry Sansing said MUW will not comment on why Bryson was asked to resign because it is a personnel matter.
"The best reaction," Bryson says, "and the most encouraging reaction I have received has been from the students." She added that the students who have heard the talk, "They have been so enthusiastically supportive of me."
Bryson has contacted the American Family Association Center for Law and Policy and is considering taking legal action against the school.
Some of them--many of the theropods--were experimenting with warm-bloodedness so that they could hunt at night and pursue (rather than just stalk) prey. You can't draw a sharp line and say "These are true reptiles and these aren't." For some scientists, the answer is to move the clade Aves, formerly a class of its own, under Reptilia. That is, birds are thus considered warm-blooded reptiles. Here's a tree putting them under the coelurosaurs.
BP, this kind of readjustment happens because the Linnaean system of categories was originally developed 250 years ago based one man's view of the then-known forms which life had taken. There is no reason to think that every "bin" he created then would be bordered with an uncrossable, inviolable barrier or that his bins themselves were magically "correct." The bin assignments, and the number and nature of the bins, are arbitrary. That said, however, the very nature of the enterprise will tend to make the classifications correspond to the branchings of a real historical tree of life as understood by evolution and ignored or misunderstood by people who think the bins are "created kinds."
As you go back in time (or down in the sediments) the bin boundaries "blur" as forms start getting harder to tell from the forms in other bins. Looking back in time reverses divergence.
What are you gonna do when they don't?
Dinos did not have turbinates, and therefore, were cold blooded.
Both sides, take your pick.
Yes indeed. I have this problem that when someone shows results without stating methods, I am entirely unable to determine by extrasensory perception what they did. Most scientists have the same deficiency. That's why we put 'methods' sections in papers. I can see that, having a direct line to God, you must find it hard to empathize.
Exactly. Creationist calls for physical evidence ("Where o where is the missing link?") which you already have lawyered away as meaningless are a simple rude waste of everyone's time. You demand the broomstick of the Wicked Witch of the West, with the implication that you would acknowledge such a thing as proof. You won't, and anyone who has watched the Creationist Dumbshow before knows it.
Or maybe you're just cold-blooded.
Nope. The point was for you to do your own research because nobody can understand it for you. If you prefer to believe otherwise, you'll just end up like Anti-Pope GoreMMM, skull-full-of-mush, lacking-Data-man, or weasel-wording-AC.
OK. The evolutionary model (see p. 2158 of the Ciona reference) shows urochordates diverged first from cephalochordates and vertebrates; cephalochordates and vertebrates diverged from each other shortly thereafter. So, to first order, you would expect about the same distance between Ciona and Branchiostoma as between Ciona and Danio.
This is the analysis of ADH3 sequences from the paper of Canestro et. al. that I cited previously
Pair compared time of divergence (fossil evidence) ADH3 'evolutionary distance' primates/rodents 65-100 MY 0.06 Reptiles/mammals 288?310 0.12 Fish/tetrapods 400 0.23 Hagfish/gnathostomes 555 0.30 Cephalochordates/vertebrates - 0.37As I understand it, the 'evolutionary distance' is largely a function of the number of amino acid substitution rate. They then estimate from the correlation line that the Cephalochordates and vertebrates diverged around 690 MY ago. They didn't analyze the Ciona ADH3 (probably didn't have it when they wrote the paper), and so I can't tell you how it would fit in. Note, however, that quoting numbers generated by a canned program without a full understanding of the methods they've used, and the limitations of the results, is notoriously dangerous. As a chemist who does a lot of computation, I'm perpetually wary of it. I would strongly recommend looking at the data by hand, aligning the sequences, and then counting substitutions before drawing conclusions from BLAST; if you get about the same number it does, you're on safe ground. I started to do that last night with the Ciona/Branchistoma data with a consensus alignment of all ADH genes, and I got between 249 and 252 Ciona/Branchiostoma identities over a 340 amino acid consensus aligned seqeunce, and 264 and 192 identities between Ciona and two Danio genes.
Remember, standard theories claim that there was a massive increase in the genome around the beginning of the vertebrate line, and that one Ciona ADH3 gene gave rise to several ADH vertebrate genes. So, of the two I tested; one was a little more similar to Ciona, and one was a lot less similar. When you pick an ADH3 gene from a vertebrate, you're picking the protein from a family of daughter proteins that is most like the protein in Ciona. So, understandably, there is a little selection bias. The vertebrate ADH1s are also daughters of the Ciona ADH3 gene, and they're a lot less similar. ADHs are also an atypical family of enzymes; they have an enormous variability of substrates between different species.
One solution might be to pick a more conserved protein. I started with cytochrome b5 last night; it's short, has both highly conserved and variable regions, and is found in most every organism, and as far as I can recall retains the same function in almost all organisms. Unfortunately I have two papers to give at an ACS meeting in ten days time, and I don't have the time at the moment to explore this further. However, I promise I will return to it in early April.
Plus, I hear tinfoil is almost impossible to come by in Liaoning province.
Why is that discussing the origins of life with you and your fellow travelers here, is like discussing politics with a Liberal?

Really?
Can I guess that English is not your mother tongue?

The only yelling, fussing, and whining is from you and your fellow seminar posters - in fact, it seems to be all that you do. And even three-year-olds quickly learn that it's unproductive.
