A confused mess, part 1

I follow Uncommon Descent to keep up with what the cdesign proponentsists are up to, even though I’ve been banned from commentingUncommon Descent pushes out about three times as many articles as Evolution News & Views, and it’s clear that less than a third as much thought goes into each one. Worse, the articles’ authorship is rarely identified, robbing me of my second favorite sport after fly fishing, pointing out creationists’ self-contradictions. For both of these reasons, I don’t comment on their posts nearly as often. But if you read this blog at all, you must know that I can’t pass on a video that 1) claims to provide evidence against evolution and 2) has Volvox in it.

Another take on volvocine individuality

Dinah Davison & Erik Hanschen

Dinah Davison and Erik Hanschen.

A couple of weeks ago, I indulged in a little shameless self-promotion, writing about my new chapter on volvocine individuality in Biological Individuality, Integrating Scientific, Philosophical, and Historical Perspectives. Now two graduate students in the Michod lab at the University of Arizona, Erik Hanschen and Dinah Davison, have published their own take on volvocine individuality in Philosophy, Theory, and Practice in Biology (“Evolution of individuality: a case study in the volvocine green algae“). The article is open-access, and Hanschen and Davison are listed as equal contributors.

Non-model model organisms

Jim Umen, the lead organizer of the upcoming Volvox meeting, has written a section for a new paper in BMC Biology, “Non-model model organisms.” Like all of the BMC journals, BMC Biology is open access, so you can check out the original.

The article surveys organisms that, while not among the traditional model systems, have been developed as model systems for studying particular biological questions. The paper has an unusual format, with a discrete section devoted to each species, each written by one or two of the authors. Aside from Volvox, there are sections on diatoms, the ciliates Stentor and Oxytricha, the amoeba Naeglaria, fission yeast, the filamentous fungus Ashbya, the moss Physcomitrella, the cnidarian Nematostella, tardigrades, axolotls, killifish, R bodies (a bacterial toxin delivery system), and cerebral organoids (a kind of lab-grown micro-brain).

Dr. Umen presents Volvox and its relatives as a model system for understand the evolution of traits related to the evolution of multicellularity:

A few more things called “Volvox

I like to document uses of the name “Volvox” that don’t refer to the green algal genus, for example Volvox the shipVolvox the paintDJ Volvox, another DJ VolvoxVolvox the art galleryVolvox the Turkish metal band, and another Volvox band (“one of the most extraordinary bands ever to emerge from Melbourne, or in fact anywhere else”).

Postdoc Katrin Schmidt recently brought a few more to my attention; I’m really not sure if they have anything at all to do with proper Volvox:

The Volvox

Volvox the book.

Cells, colonies, and clones: individuality in the volvocine algae

Biological Individuality

As I mentioned previously, I have a chapter in the newly published book Biological Individuality, Integrating Scientific, Philosophical, and Historical Perspectives. The chapter was actually written nearly five years ago, but things move more slowly in the philosophy world than that of biology. Finally, though, both the print and electronic versions are now available; here is the electronic version of my chapter. The book currently has no reviews on Amazon, so if you want to give it a read, yours could be the first. If you’re interested in current and historical views on individuality, there is a lot of good stuff in here, including contributions by Scott Lidgard & Lynn Nyhart, Beckett Sterner, Andrew Reynolds, Snait Gissis, Olivier Rieppel, Michael Osborne, Hannah Landecker, Ingo Brigandt, James Elwick, Scott Gilbert, and Alan Love & Ingo Brigandt.

Volvox 2017: early registration extended

Volvox 2017

Discounted registration for the Volvox 2017 meeting has been extended to June 16th. This is a pretty good deal as scientific meetings go: $550 for faculty includes registration, most meals, and a shared room. Registration for postdocs and students is $100 less, and there are travel grants available. If you’ve been debating whether or not to go, it’s decision time: prices will go up $100 after the 16th.
