I’m joining Larry Moran in applying the thumbscrews to John Logsdon, who has just started a new blog. He’s got to do more than just one short tease of a post!
The Lynn Margulis blog tour has moved on to Memoirs of a Skepchick—if you weren’t satisfied with her answers here, you can try again.
You really should take a closer look at this map of publication links between scientific disciplines. Here’s the description:
This map was constructed by sorting roughly 800,000 published papers into 776 different scientific paradigms (shown as pale circular nodes) based on how often the papers were cited together by authors of other papers. Links (curved black lines) were made between the paradigms that shared papers, then treated as rubber bands, holding similar paradigms nearer one another when a physical simulation forced every paradigm to repel every other; thus the layout derives directly from the data. Larger paradigms have more papers; node proximity and darker links indicate how many papers are shared between two paradigms. Flowing labels list common words unique to each paradigm, large labels general areas of scientific inquiry.
There’s an amazingly detailed version of the map available at Seed, and it visualizes an important point: all of the sciences are interconnected, sometimes very indirectly, but the contacts are there. When some clueless ideologue (like Michael Egnor, who is up to the same old tricks again) tries to split off a major subset and pretend it is irrelevant, he has to ignore the breadth of science.
The latest Nature reveals a new primitive mammal fossil collected in the Mesozoic strata of the Yan mountains of China. It’s small and unprepossessing, but it has at least two noteworthy novelties, and first among them is that it represents another step in the transition from the reptilian to the mammalian jaw and ear.
What do you know…just last week, I posted an article dismissing a creationist’s misconceptions about pharyngeal organization and development, in which he asks about the evidence for similarities between agnathan and gnathostome jaws, and what comes along but a new paper on the molecular evidence for the origin of the jaw, which describes gene expression in the lamprey pharynx. How timely! And as a plus, it contains several very clear summary diagrams to show how all the bits and pieces and molecules relate to one another.
The short summary is that there is a suite of genes (the Hox and Dlx genes, which define a cartesian coordinate system for the branchial arch elements, Fgf8/Dlx1 genes that establish proximal jaw elements, and Bmp4/Msx1 genes that demarcate more distal elements) that are found in both lampreys and vertebrates in similar patterns and roles, and that vertebrate upper and lower jaws are homologous to the upper and lower “lips” of the lamprey oral supporting apparatus.
The chat with Lynn Margulis is over; thanks to Dr Margulis and all who participated. I’ve included the transcript below the fold.
Lynn Margulis has sent the opening statement for her blog tour below. You should feel free to respond to it, raise other questions of any relevant sort, or say whatever you want in the comments; she’ll be along later today to respond to those that interest her. I will be policing the comments, so trolls, please don’t bother; serious comments only, and keep in mind that she’s only going to respond to a limited subset, so make ’em good.
In addition, she’ll be available later today in the Pharyngula chat room (channel #pharyngula on irc.zirc.org; if you don’t have an IRC client, that link will let you use your browser to join in) from 12:00-1:30pm ET. Dive in there for a more interactive give-and-take with Dr Margulis.
What a pleasure to write openly for Pharyngula even though, in principle, I am leery, even with this blog, of any internet participation. The haste and style online by its very breezy nature generates misinterpretation and misunderstanding. Nothing online written about me is entirely accurate, except perhaps my address at the University of Massachusetts.
Although misunderstanding permeates all human communication, the internet amplifies these tendencies. Sound bite-hype is far more useful to those who assert religious truths and would banish authentic science from the public sphere than to the scholar or scientist. Science itself, and even more so, science writing, ever cautious, ever tentative and ever questioning is permeated with boring hesitancies and stuttering qualifications. Most readers simply ignore it since they find it incomprehensible. The more accurate the scientific description, the more daunting the language to any outsider. The more clear the expression of a scientific idea is, the more specialized the terminology. The clearest scientific ideas are mathematical equations opaque to all but the specialist.
So, when reporters and popular writers attempt to communicate real science the plagues of distortion, misunderstanding and misrepresentation are inevitable. Any statement outside the immediate purview of the detailed science tends to be “translated” into common language. To express new ideas that challenge the paradigm in which the scientist works new language is required. If the language is too new neither the scientist nor the science popularizer is understood. Especially when one’s work is heterodox to the prevailing trend -it is easy to be dismissed as a “crank” or “on the fringe.” Or, even more likely, to be ignored. The convenient fiction, created by marketers and politicians, that “consensus” plays a major role in original science, helps to generate confusion in the lay public about the vast difference between established scientific fact and ideologically-driven nonsense.
Scientists seek evidence. Eclipses could not be predicted, calendars could not be distributed, tide tables could not be published, airplanes could not be built to fly, food plants not grown, bridges nor buildings built, in the absence of precise knowledge of celestial mechanics, gravity, air flow, soil nutrients, flowering plant sexuality, metal compression and tensional strengths, etc. Scientific facts, scientists know, lie in the details. Explanatory power, falsifiable prediction, reproducible experimental results underlie all scientific theory. Within the detailed framework there are no “scientific controversies”. Theories explain, hypotheses make precise predictions either verifiable or not, results are either reproducible or they aren’t. The most serious communication problem is that specialized knowledge, an arcane literature and years of specialized training are required for participation in any science and all science by its very nature is severely limited to its objects of study. No botanist can participate meaningfully in nuclear physics nor can physicists analyse genetic data. Science communicators, even the very best, and there many (e,g, those who write for Science News, Nature, Science and the New York Times Tuesday pages, National Public Radio and the like) can not comprehensibly describe anything without bias and oversimplification, ever. No writing, if it is to be widely understood, can be without bias. I believe that no meaningful distinction or description of anything, science included, can be made without an historical, including natural-historical, context. Yet most scientists live in the “now”; they tend to lack a long view and any knowledge outside the limits of their own specialized field. Sometimes their “field” is more a budget constraint or a whim of a dead scholar than a natural science. Some “fields”, clearly are not natural science, like the field called “cancer”. This implies that science writing too unavoidably displays bias, prejudice, nationalism, profound ignorance, incompleteness and other manifestations of “slanted truths”.
Scientists too often know little about the cultural and historical context of their ideas. Neo-Darwinians biologists, for example, really believe that “evolution” is a subfield of biology, especially zoology. Hence they ignore the non-zoological components of evolutionary science (e.g., all of historical geology including especially paleontology; environmental science, ecology, atmospheric chemistry, microbiology, etc.) They rarely acknowledge that their theoretical frames derive from an Anglophone-capitalist model, and inevitably carry the prejudices, assumptions and philosophical orientations of our milieu. Because most people interested in evolution live in an Anglophone-capitalist culture, assumptions of neo-Darwinians are unstated. Concepts such as the validity of “cost-benefit” and “competition vs. co-operation” terminology or the superiority of mathematical analysis are uncritically assumed. Many unstated assumptions are made because of the bias of the “evolutionary biologists”, the majority of whom have animal biology/zoological training who share our cultural orientation. There is, in fact, paltry evidence for the neo-Darwinian “thought-style”. The staunch neo-Darwinist claims have become less and less valid as information from other fields (e.g., molecular biology and the fossil record) has increased. It is not unusual, especially in the science of evolution, that theories contradictory to the neo-Darwinian “thought-style” are ignored or rejected, not on the basis of their claims, or proof of those claims, but on the, often unconscious, grounds that they do not agree with our biases. Read Ludwik Fleck.
So here we have an opportunity for open discussion – to listen to nature, to perceive the nature of nature, to reveal scientifically-documented facts beyond prejudices. We attempt, with civil dialogue based on sound science, to achieve, in good faith, an understanding of each other and the world. Science is limited, what is known for sure is miniscule in contrast to the great unknown, but the deliberate faith-based distortion of what really is known is despicable. We will avoid the cant, rant and desperate attempt to distort so common on both sides in the so-called “religion-vs science” debate. Whiteheadian philosophers, many Unitarian and Buddhist scholars, all true scientists agree with David Bohm’s sentiment that “science is the search for truth” whether or not we like that truth. And Emily Dickinson’s sentiment, from her poem “Tell all the Truth but tell it Slant ” is even more compelling:
As Lightning to the Children eased
With explanation kind
The Truth must dazzle gradually
Or every man be blind–Lynn Margulis,

I was reminded of one of the more comical, but persistent misconceptions by creationists in a thread on Internet Infidels, on The Coelacanth. Try doing a google search for “coelacanth creation” and be amazed at the volume of ignorance pumped out on this subject. I’ve also run across a more recent example of the misrepresentation of the coelacanth that I’ll mention later … this poor fish has a long history of abuse by creationists, though, so here’s a brief rundown of wacky creationist interpretations.
Here’s an interesting opportunity: Lynn Margulis, the controversial scientist, is going on a ‘blog tour’ to promote her new imprint of science books called Sciencewriters Books. What does that mean? She’s going to hang out for a little while on a few blogs and chat and answer questions. If you’ve wanted to have a conversation with the author of the endosymbiont theory and critic of neo-Darwinian theory, here’s your chance.
The tour will kick off on Monday, 12 March, at Pharyngula. She’ll be sending me a short article that I’ll post that morning, and we’ll collect comments and questions. Later that afternoon or evening, she’ll browse through those comments and answer the ones she finds interesting.
In addition, she’ll be available in the Pharyngula chat room (channel #pharyngula on irc.zirc.org; if you don’t have an IRC client, that link will let you use your browser to join in) from 12:00-1:30pm ET.
So mark it on your calendars: an online conversation with Lynn Margulis, next Monday, 12 March, at Pharyngula.
Vox Day asks a question: what is my definition of science? It’s a bit weird coming from him — he is not usually that lucid or civil — but OK, I’ll take it seriously.
Unfortunately, “science” is one of those hugely polymorphic terms that carries a tremendous amount of baggage, and any one definition is going to be inadequate. This is one of those subjects where a smart philosopher (Janet? John?) could go on at amazing length, and even then, everyone will argue with their summaries. I’ll just charge in, though, and give a couple of shorter definitions off the top of my head.
