T.Rex and Daffy Duck

It is hard to believe that a bat and a blue whale are of a kind. But in establishing kinship, the differences don't matter -- they're both mammals because of certain similarities. This is Jack Horner's point in my short item today about a new paper saying that birds and dinosaurs had different types of lungs. It's the similarities that establish that birds are a continuation of the dinosaur line; differences don't refute that, even if some scientists insist otherwise.

This may seem a little esoteric, but I think it provides a glimpse of a broader issue: It is not necessary to tie up every loose end in order to establish that a theory is fairly robust. Moreover, the existence of a loose end is not evidence that the theory is false. It is merely a reminder that we are not omniscient creatures.

Here's the piece:

There is compelling evidence that birds are dinosaurs. Both have hollow bones and hard-shelled eggs. Pelvis, wishbone, wrist bone, three-toed hind foot -- they're strikingly similar.

There is also evidence that dinosaurs sat on their eggs, just like birds. Specifically, birds are believed to be descendants of a type of dinosaur known as maniraptoran therapods.

But as with all orthodoxies, there is dissent. Two scientists at Oregon State University have published a paper in the Journal of Morphology arguing that dinosaurs did not have bird-like lungs.

"No known therapod dinosaur could possibly have ventilated a birdlike lung," said zoologist John Ruben, who co-authored the study with colleague Devon Quick.

They researched the skeletal-muscular structure supporting the air sacs that enable a bird to breathe. No such anatomy is known in therapod dinosaurs, Ruben said.

"It's far more like that the two groups share a common ancestor and for at least some period of time evolved in parallel," Ruben said. The birds-are-dinosaurs model is popular because "it allows people to think that somehow velociraptor sprouted feathers and flew off in the sunset and now is flying around your back yard."

But Jack Horner, curator of paleontology at the Museum of the Rockies in Montana, said the criticism is based on a misunderstanding of how we can tell species are related.

"Differences don't matter," Horner said. "It doesn't matter how many differences there are between birds and dinosaurs because there are hundreds of similarities."

There is no other animal in the fossil record more closely related to birds than therapod dinosaurs, he said, and the hypothesis is based on hundreds of characteristics.

It seems to me that this important point, that differences don't matter, can be taken beyond biology all the way to sociology.

I think the main quibble is when the two lines diverged.

I personally side with the guys who think birds and theropods split off much earlier than currently thought.

This doesn't invalidate the idea that they're the most closely related group to birds known, living or fossil.

Although that's how it often sounds after academic disputes go through the pop science wringer...

*rubbing hands with glee over the therapods because they're fun* Thanks, Joel, for the cool update regarding the lungs.

I ran into a loose end big-time just this morning, in a far-too-brief conversation with Kate Wellspring, collections manager of Amherst's Museum of Natural History. Museumn's closed today to the public, but Wellspring was working.

She said that my cousin F.B. Loomis was one of the worst notetakers of all the paleontologists in the short history of paleontology in the United States. AAARRRgghh!

She said researchers had come to Amherst to attempt to study Loomis's writings, journals, field notes and there's zip, nada. The researchers leave empty-handed. A man of action, not of words, apparently. Perhaps more of a Roy Chapman Andrews, an Indiana Jones-type figure. *laughing*

Neat Amherst website mentioning that Massachusetts was once connected to Morroco--and showing that Connecticut was pretty much equatorial at one time and the Connecticut River Valley was a tear of sorts when the land masses began to separate.

Like this passage very much about Wyoming geologist J. David Love, from John McPhee's "Rising from the Plains":

As a graduate student he had to advance his reading knowledge of German, which he did over campfires on summer field work in the mountains of Wyoming. One book mentioned an inscription above a doorway at the German Naval Officer's school in Kiel--an unlikely place for a Rocky Mountain geologist to discover what became for him a lifelong professional axiom. As he renders it in English: "Say not 'This is the truth' but 'So it seems to me to be as I now see the things I think I see.'"

Never saw it, though I was kinda interested to.

Well, of course a T. Rex and a canary have different lung systems and mechanisms. One has chest muscles and systems for flying and for long endurance at altitude. The other is for processing the odd brontosaurus roadkill as a giant all-you-can-eat buffet. Sorta like the Golden Skillet but without trays and sneeze guards.

To me, the precise taxonomical relationship of dinosaurs and birds is less important than whether or not the underlying theory advances scientific knowledge. For there have been many provocative theories proposed in science that fail to stand up to rigorous examination, yet have still been worthwhile. Consider the so-called “Gaia Hypothesis” that, in its most extreme form, views the planet as some sort of living entity. Now while this theory has lost a lot of its luster over the years, it has led to a greater appreciation for feedback loops and many other unsuspected linkages whose existence might not have been as seriously investigated if it hadn’t been for this theory.

I mean, would scientists have so closely compared avian and dinosaur lungs if these scientists weren’t actively trying to prove, or disprove, the notion that T. Rex and Daffy are, indeed, kissing cousins?

Besides, of course, biology is messy. There are always lots of variations and retrograde evolutions and similar things. Anything having to do with life tends to resist the same kind of hard conclusions that characterize many aspects of the physical sciences. Which is why I have always felt that the so-called "life sciences" are actually, by far, the most difficult to understand.

Howdy. Joel said more than he knew with this: "It is not necessary to tie up every loose end in order to establish that a theory is fairly robust. Moreover, the existence of a loose end is not evidence that the theory is false."

In a nutshell, that is the basis of our criminal justice jury trial system. Almost every trial has loose ends and some of them wave pretty vigorously. That doesn't mean a defendant didn't commit the crime beyond a reasonable doubt. People who think a criminal jury trial will get to "the truth" are always disappointed. The truth may be out there, but its ambiguities are alive and well in the courtroom - just as in the scientific lab.


I hope that Jack Horner in his corner office gets plum pie for his bonus.

Thanks, Mudge. You got it all. I thought he spoke a mouthful, and more.

Ivansmom, I believe too much is on the line for "truth" to ever come out in a courtroom. That's for television.

Wilbrod, I read that statement as simply indicating that at that frequency the wavelength is, in fact, longer than a certain length. I don't think they were challenging the fundamental relationship which is, indeed inversely proportional.

There is an interesting subtlety, though.

Frequency X Wavelength = Wave speed in that medium.

Further, wave speed is usually proportional to density. Therefore, the wavelength of a sound wave at a given frequency will change depending on the density of the material through which it travels. (Same deal for light waves and seismic waves.)

This is why the ideal ear size of an ocean critter can be different (and typically smaller) than a land critter.

Physics is, like, everywhere.

Many little bits and pieces:

(1) Jack Horner has been a leading light in dinosaur paleontology, at least to the extent that the non-specialist hears about it, for something like 30 years. I'd guess that he's about 15 years younger than Bob Bakker. Bakker came in with the introduction of paleo-engineering as an analytic discipline. Horner is more of a paleo-histologist, concerned with things like the interior structure of bones and analogs to to modern critters -- working from the assumption that certain structural adaptations are forced by lifestyle, physics, and chemistry, more than an artifact of evolutionary history (although evolutionary history controls which adaptations are possible).

(2) I gotta say -- if you don't take the notes, you may be having fun, but you're not doing good science. I hope that Dr. Loomis kept the critical notes, and that the scholars are disappointed only because they lack the off-topic notes that would better illuminate the man's personality.

(3) I met someone on Saturday who painted a landscape near Mianus. She pronounces it "my annis." Kind of disappointing, really. http://www.kesrahoffman.com/

(4) Hertz = Hz is a measure of frequency. Higher frequency implies shorter wavelength. Frequency times wavelength = speed of propagation in a medium. All just as RD said, I am just confirming the information.

Yes, Tim, you may be right on your #2. The field notes for paleontologists such as Barnum Brown for his endeavors for NYC's American Museum of Natural History list only the finds and pertinent discovery information, and read like ledgers. It was others such as Arthur Lakes who painted the watercolors of the digs and who made extensive notes which later proved to be valuable. Marsh hired both the worker bees and the painter bees and not always did the two types of men in the field mix very well...but in the end both men made significant contributions.

Read that sentence again, RD.

It's about giving the context for the lay reader, if you'll see it.

I think "smaller than" would be appropriate, since it would imply that shorter wavelengths scatter more easily, which is true.

How it reads right now, the reader has no information on what Hz means at all, and may think that larger waves actually tend to block easier.

It's not a misfact; it's just sloppy writing.

I am in the camp that questions the facile equation "birds are dinosaurs". I am not inclined to question that birds are descended from therapod dinosaurs -- to the extent that I have been handed the evidences and inferences (as received knowledge), the case seems pretty solid. My disagreement is with the notion that birds can be fully classified merely by identifying their ancestral group. By that notion, 'mammal' and 'dinosaur' both are bogus classifications and we must all be identified as reptiles; or, go back farther and declare that we are nought but colonial eukaryotes. At some ill-defined point, I think enough differences pile up that one can declare the emergence of a new species or a new genus or a new order.

Nature did a very interesting experiment 65 million years ago -- it applied extreme stressors to the environment and, among the dominant animal order of the day, the only survivors were what are often called 'the avian dinosaurs.' That seems like a rather specific selection criterion: only those dinosaurs survived that flew, or whose ancestors had flown. None of those dinosaur groups survived whose ancestry included no flying members. My inclination is to consider this selection criterion as indicating some sufficiently large physiological difference between birds and their ancestry that they can be described as a new order. Given that both flyers and non-flyers survived (um, I'm pretty sure some flightless birds survived -- I know that some had evolved by then), it's probably not just the trivial fact of being a flyer at the time of the extinction event. Plus, of course, pterosaurs did not survive (although my memory is that they already were on the way out -- possibly because birds were better at occupying the niche). Bats were not yet present -- or at least, I have never heard of any evidence for airborne mammals at that time. Anyway, I'm willing to allow for a substantially different mode of respiration in birds compared to dinosaurs, if only because the efficiency of avian respiration could constitute one of those subtle but pervasive physiological differences that explains why birds survived when the 'other' dinosaurs did not.

So there.

Bats are so tiny that their skeletons don't survive well (same for birds' fragile skeletons).

However, bats are one of the oldest classes of mammals; 52 million years old and counting.

http://evolution.suite101.com/article.cfm/fossil_bat_flew_while_deaf

http://www.ucmp.berkeley.edu/mammal/eutheria/chirofr.html

There is a hot debate precisely when bats branched off, because it was before any of the modern classes developed-- either from a proto-insectivore/chiroptera clade, or from a larger proto-clade including carnivores, artiodactyls, perissodactyls, and cetaceans.

(Clades are artifical groups formed by cladistics-- analysis of primitive traits. This may or may not concide with actual genetic analysis or fossil record data.)

Of course it's pronounced that way, Tim. How have YOU been saying it all this time?

Posted by: yellojkt | June 15, 2009 4:09 PM | Report abuse

You raise a very interesting question, SciTim. If, 65 million years ago, a comet explosion wiped out all the dinosaurs and most other lifeforms, how come birds (avian dinosaurs, or whatever) survived? One would think that a planet suddenly covered in smoke and ash and debris and whatnot would wipe out flying creatures even more selectively than anything else. And generally speaking, aren't birds relatively fragile creatures compared to other animals? (Viz., canaries being used in coal mines because they are even more sensitive to gases or whatever, than humans.)

Also, do we not know that alligators and similar creatures are some 220 million years old, and therefore survived the comet extinction 65 million years ago? And we note they are egg-laying reptiles, yes? So do we know that water-born reptiles tended to survive, while land-based dinosaurs did not? Allighators can survive at relatively low oxygen levels (surely as existed during the Big Boom and after). Do birds do well in low oxygen (one immediately thinks of high altitude)?

There was a sharp increase in the earth's oxygen level 50 million years ago, which scientists think led to the rise of mammals.

Posted by: curmudgeon6 | June 15, 2009 4:20 PM | Report abuse

Mosasaurs, plesiosaurs, and ichthyosaurs all died out with the K/T boundary, while crocodilians survived. As far as the mosasaurs are concerned, the displays at the National Museum of Natural History tend to promote ecosystem collapse as eliminating the food supply.

Birds breathe very efficiently. I suspect canaries are chemically more fragile than miners only because they are tiny and therefore need to process a lot of oxygen to maintain body temperature.

Fragility for fossilization is different from mechanical fragility. Sharks fossilize very poorly, but few would argue that they are terribly fragile creatures.

ScienceKid#1 considers that we may have more success in breeding monitor lizards into mosasaur-like animals than breeding large predatory flightless birds into pseudo-tyrannosaurs. It fails to test any useful hypotheses about large-animal predation vs. scavenging, but it would be pretty cool. And scary.

Also, a sharp decrease in the levels of carbon dioxide, Mudge. This helps trigger respiration rates-- think of how dizzy you get when you hyperventilate-- that's because the carbon dioxide levels in your blood drop drastically.

Studies with carbon dioxide levels indicate that higher levels of CO2 in the atmosphere would trigger the growth of larger, but less nutritious plants, forcing herbivores to be large enough to eat a ton of fiber to get the digestion necessary. A low metabolism would be helpful too (voila, huge dino herbivores).

The problem is that huge species just go extinct very easily, as they have a lower effective population size.

We're all arguing why dinosaurs went extinct, but we forget the palezoic mammals were really huge too, and they went extinct like that, too.

Elephants are the one remaining megafauna genus, and they've evolved a lot since those days-- and they, too, face extinction from smaller mammals that kill 'em and take their food and change their habitats.
Unlike their mammoth cousins they also have adapted to hot weather by use of bigger ears, trunks, lack of fur, etc-- and great memories.

Maybe it was the same for the dinos, just minus the technology of humans.

Between temperature and atmosphere changes, increasing numbers of small animals passing on diseases and eating their eggs, etc, it wouldn't take much to crash population numbers.

The best argument for classifying birds as distinct from dinosaurs, in my opinion, rests on their brain size.
http://www.scientificblogging.com/news_releases/big_brains_faster_evolution

Crocodilians have a relatively more advanced brain than other reptiles, and have true cerebral cortexes.

Crocodilians might have survived because they had the wits to duck danger.

May I brag to my imaginary friends?

After almost two years away from the gym (lack of gumption, among other things), I put on the gear and went. All I did was 10 minutes on the treadmill at 2.5 mph, but it was a nice start. The lower back didn't act up and the knees were reasonable (I wear neoprine knee braces when I'm doing this). I didn't do any weight training, because I have to get evaluated by the house PT first and then get a trainer to work up a program. I expect all this to happen in the next couple of weeks.

So, I'm feeling pretty good (well, to tell you the truth, I'm feeling a wee bit smug and *very* proud of myself). I so want to get the semblance of a strong body back, and this is the way to do it.

Doing a drive-by, since I'm in the field right now...

To go all technical, Horner is talking about the difference between synapomorphies and apomorphies. Synapomorphies (or shared, derived characters) are novel features found in two different species. These tend to indicate that the two species share a common ancestor; that's why they share the feature). Some characters appear to be synapomorphies but really aren't; instead they evolved convergently. Systematists, paleontologists, etc. get the big bucks (!) for figuring out which is which.

Apomorphies, on the other hand, are novel features that are unique to a single group (they aren't shared with anyone else). These don't generally indicate anything about relationships, instead, they're the features that are used to define a particular taxon. An apomorphy of modern birds is the fusion of the bones of the hand; another may be the unique lung. But as Horner said, these essentially tell us what make something a bird, not what it evolved from.

As for the Cretaceous extinction, a lot of the points raised earlier in the boodle are the same points that the folks that work on this extinction are looking at. In particular:

Why all pterosaurs but not all birds?

Why theropods/flightless birds (there were flightless birds, but apparently none survived the extinction).

Why all the marine reptiles except turtles?

Why all large animals, regardless of their taxonomic group?

Why mosasaurs, but not monitor lizards (close relatives)?

Why were calcareous phytoplankton apparently hit harder than silicious phytoplankton?

Why did flowering plants mostly do well, but not a lot of other plants?

Why were ammonoid cephalopods completely wiped out, but not closely related nautiloid cephalopods?

These questions probably don't all have the same answer.

Turns out, extinctions are complicated. No one seriously questions anymore whether or not an impact occurred at the end of the Cretaceous or that it was a major factor in the extinction. But, as with most things, the initial simple explanation turns out to only be the beginning of a much more complicated story--it's the thing that hopefully gets us looking in the right direction, and asking the right questions.

I think of the French/Belgian paleontologist Dollo who studied the fossils of Bernissart in Belgium for decades and devised the term ethological paleontology, from which are derived paleobiology--how an organism relates to its environment, fields more akin to zoology and botany, and biostratigraphy, akin to geology.

If the environment changes rapidly (possibly culminating in mass extinctions), survival would depend on what changes (air, water, land, chemical) and to what degree. Also availabity and abundance or scarcity of food stuffs: flora, fauna and proteins. Carnivores vs. herbivores. Couple that with each organisms structure and ability to adapt and survive by bettering the competition by outwitting them and/or surviving the competition by brawn, a better set of choppers, ability to outrun, longer forearms with a better claw. Also locomotion--whether land, water or air or a combination such as the amphibians, defense mechanisms. Advantages obtained through genetic adaptations.

ScienceKid#1 really appreciates Hopeful_Monster's commentary and is busy schooling me right now. When I was kid, I was a dino-geek; but I have never even come close to the ScienceKid's mastery of cladistics synapomorphies (a word I have only just learned) and apomorphies (another word I have only just learned).

Frostbitten, we went from freaking cold spring to hot summer in the space of a day. No one has the air conditioners up and running and boy do we need them. In short, more hot dry stuff coming your way. And if by chance the air is humid, well, you have my moisture. Could you send it back by mail? I'll pay the shipping.

Thanks Mudge for the cloud picture. I think I have seen that sort of clouds once before.
I would have been about 14, and we were picking tomatoes, potatoes and whatever else was out in the garden. I remember it not so much for the clouds but for my youngest sister, who at 4, thought the sky looked scary. We teased her horrendously and the only reason I remember the day and the clouds is because it was the day she got her little girl nickname.

Two family favorite jokes which I can remember:

From the Boy (certainly Him), age 4: "Why did the cookie go to the hospital?" "Because he was feeling crumby."

From the Boy and Ivansdad, about age 3 (referencing a Star Wars character which guarded Jabba the Hut): "Knock knock." "Who's there?" "Pig." "Pig who?" "Pig with an axe."

My own personal favorite, I think from Lewis Carroll but am not sure:

"Why is an orange like a vest?" "It has no sleeves."

I used to ask the Boy, "Why is a raven like a writing desk?" and when he said "I don't know, why?" I'd laugh and laugh.

That's all I've got.

Mudge, we took Ivansdad to the book store and the electronics store (and the women's shoe store, but that was really a side trip) this past weekend. Everywhere, we asked, "Is there a Father's Day present for you here?" We cannot buy electronics of any kind for Ivansdad unless he is present and approves, since he knows more about them than we do (for those counting, the Boy is next in the knowledge line and I am last). We have all kinds of gadgets and doohickeys and acquired a lawn tractor last year, and he seldom wears ties, so we're stumped.

I offered to get him a rabbit of his very own. This did not go over as well as I had hoped. Of course I would never acquire a second rabbit. I believe at this point Beatrice believes she is the only rabbit in the world, making her supreme Queen of the obviously superior species, and we are put here to serve her. It would be cruel to disabuse her of this notion.

I love ScienceKid#1's song!

Telling synapomorphies from apomorphies is usually very difficult, and sometimes impossible. The standard, cladistic way is by parsimony analysis; who is most similar? So, for example, for Species A, B, and C suppose the following is true:

A and B share character 1
A and C share characters 2, 3, 4, 5, and 6

The most likely scenario is that A and C are most closely related to each other, because they have 5 characters in common while A and B only have 1, and A and C have none. So how do A and B come to share that character? Very likely it's a convergence.

(Note: there is a possible alternative in this example. Character 1 could be a primitive character found in the common ancestor of A, B, and C. In that case, the character is lost in C but retained in A and B, making "loss of character 1" an apomorphy of A. In fact, in this particular example, the alternative is the "more parsimonius" explanation, because it requires fewer "evolutionary events".)

Besides looking at the distribution of the character in question across taxa, there are often subtle differences in convergent characters that are otherwise very similar. Perhaps the structure is formed from a different set of bones in each, or perhaps the characters have a different underlying genetic basis (in living critters), or maybe there is a set of fossils for each lineage showing directly how each species evolved the similar feature independently.

I first heard of cladistics in a presentation by one Gareth Nelson in 1973. I figured his stuff about phylogenies of fish made sense--for fish--but would never work with the muddled evidence and abundant polyplody and hybridization (resulting in "reticulate evolution") typical of plants.

Turned out the guy (and a jerk name V.R.Ferris who chain-smoked on a stage clearly labelled "No Smoking") had more going for him than I thought.

I think graduating from High School is actually a much bigger deal for students than most parents. The big deal for us will be when he leaves for college.

What I want to know is whether the debate between Ostrom and Feduccia over feathered dinosaurs was ever conclusively settled? Feduccia predicted "the theropod [What's the correct spelling, therapod or theropod?] origin of birds will be the greatest embarrasment of paleonotology in the 20th century."

When all else fails, conversation-wise, talk of the weather. We've been in extreme bake mode for at least a week. In the last couple of day the paper reports that we've had the driest 21 months--EVER. The daily temperatures are in a run of 100s, the nights, about 80 degrees. We've had only half of our annual rainfall total. Tender leaves hang like limp green swatches fo fabric from limbs. It's sane to venture out only in the early morning or late at night.

We hit stage two water restrictions yesterday. All fountains in the city have been shut off for a while now. Local TV weather people predict that if we don't conserve water this week, we'll hit stage three water restrictions by next week--and it'll be only July 1.

I have a proposal. No visitors or travelers should come to San Antonio. Shut down the airport and highways into town. Please stay home. Don't come here for business, don't bring any sports teams here. Don't shower in our town. Don't flush toilets. Don't drink our coffee. Don't create dirty dishes or sheets or towels. Please stay away in droves.

Reviewing Hopeful_Monster's postings of last night, I infer that the correct spelling is 'theropod.' This spelling is endorsed by Wikipedia (Font of All Knowledge™) and by plain old Googling of the word.

ScienceKid#1 keeps close watch on science news related to dinosaurs (including Science News, available for subscription) and has alerted me to several finds of theropods with feather impressions, particularly a number of dinosaur discoveries in China over the past decade or so. I don't recall the status of feathers in non-theropods. Looks like the birds-from-theropods line of reasoning is not refuted.

Googling "theropod feather" reveals a bunch of informative sites, at the top of which list is a Wikipedia page on feathered dinosaurs. The Wikipedia page mentions several non-theropods with possible feathers or proto-feathers. I am not prepared to research the topic extensively at this time.

Apparently, "daffy" is akin to "daff" which comes from "doff" from "don off" (as in a hat, similar to "do on" i.e., "don") which arose from Old German "tuan." I make this to be, tenuously, "off his head."

I even support their inclusion in the august halls of my government. This is akin to my trust in doctors to cure forms of drug-resistant staph which would not exist if not for those doctors.

Yoo-hoooooooo!

Anybody here?

I am here, and freshly showered. But with nothing terribly insightful to say about theropods, I fear. Or even Theraflu.

Awww, you'll make the lawyers blush, Jumper!

I'm here, too. Didn't go to work today, got an orthopedist appointment at 1:15.

I'm here, but only half-way. (I'm trying to run numbers. Most of them want to jog, or worse, do that mall-shuffle thing.) I ain't know nothing bout birthin no dinosaurs, and I try to steer clear of lawyer jokes (other than to try not to let my inner giggles show on my face).

I kept wondering if a new kit hadn't been called, but was reluctant to chime in from my work laptop.

@Jumper: The trust you describe also holds for tech people being able to fix problems of their own making. . . Not that I've ever deleted my own account or anything.

Listening to Chris Isaac right now, it's been too long!

Who's up for lunch? I have plenty of grilled salmon left from last night.

We are all getting ready for the graduation extravaganza. I keep thinking about my own high school graduation, which was held in the grandstands of the Western Washington State Fairgrounds. It was a spectacular day. I remember my grandfather sitting in the stands and waving madly at another kid who kinda looked like me. His eyesight wasn't what it once was.

Pomp and Circumstance was played, as per specifications, and many a hat, and a few gowns, were tossed. Afterwards, we all marched into the cavernous empty spaces beneath the grandstand, and the crowd erupted into joyful tears. Nothing, I mean nothing, in my life has ever recaptured that explosion of emotion.

I hope my son experiences that as well.

That would be Chris Isaak. It really has been too long.

I've never seen Son of G smiling like he was during his HS graduation.

Of course, the severe case of senioritis that had set in had made the event not seem like such a sure thing after all, so there was much appreciation on his part (and mine!).

I hope your son enjoys the day, RD, and can tolerate the tears and reminiscences that are bound to be experienced.

Ah, the joys of watching kids walk across the stage. When there are almost 700 of them, it's quite the production. (That was the experience of one of my best buddies on Sunday afternoon.)

High school graduation, I walked across the stage. Undergraduate graduation, we were grouped by colleges and stood up, were declared graduated, and sat down. Masters graduation, I went to the beach instead.

Congratulations to your son, RD_Padouk, and his parents, too.

Did anyone mention that today is Bloomsday? I don't know what a suitable tribute to Ulysses might be. Perhaps eating a lamb kidney?

Hope everyone is having a good day.

Perhaps a few grafs from an obit about Ostrom hold the answer?

http://www.independent.co.uk/news/obituaries/professor-john-ostrom-499554.html

Discovery of the Chinese feathered dinosaurs [mid-1990s] capped Ostrom's career, validating his theories that dinosaurs were active, dynamic animals, and that birds had evolved from small, predatory dinosaurs. Although the Chinese fossils were younger than Archaeopteryx, they showed that small dinosaurs must have evolved feathers long before flight.

Ostrom never became a public figure as did the colourful Bakker. But among dinosaur palaeontologists he was treasured as a father figure and mentor as well as a gifted scientist. He responded graciously to questions from children and journalists. In a posting on the dinosaur mailing list, Taormina Lepore, now a student working on dinosaur footprints Ostrom studied three decades ago, said his replies to her letters when she was nine and 12 had inspired her love of palaeontology.

Tom Holtz, a dinosaur palaeontologist at the University of Maryland who studied under Ostrom, said, "Through his work, and the research he inspired, we now recognise dinosaurs as one of the most successful lineages in the history of the planet, and one which still is present today in the form of birds."

Greetings and Felicitations to Young Padouk! Well done, Scion of RD_P!!! Huzzah! (and so on) :-)

It's somewhat annoying how a doctor's appointment can mess up one's normal Boodling routine... No jogging for me for awhile, the 'ol Achilles tendonitis has raised its ugly head.
