  • Darwin in the arts

    Tue, 2009-06-23 17:16 -- John Hawks

    The Fitzwilliam Museum, Cambridge UK, is putting on an exhibition titled, "Endless Forms: Darwin, Natural Science and the Visual Arts."

    The exhibition is accompanied by a well-produced webiste, which includes descriptions of the collection, some material for educators (including visit information for the UK), and a virtual exhibition. Some of the text may be stretching Darwin's direct influence on the arts -- a naturalistic eye goes back farther than Audubon, for example, but several sections are interesting. Here's an excerpt from "Darwin and the Impressionists":

    Edgar Degas, too, is known to have engaged directly with Darwinian theory, especially through reading Expression of the Emotions in Man and Animals soon after it was published in French in 1874. His images of dancers, singers, and criminals in the decades that followed stressed a kinship with animals in their features and gestures, and hinted at the possibility of human degeneration to an animal condition.

    I think it's an open question how much Darwinism really affected popular culture. Several of the artists represented (e.g., Robert Farren) were already representing ancient creatures well before the publication of the Origin. Artists seem to have reacted to a greater understanding of nature, and science drew on that art as well as upon itself.

    UPDATE (2009/06/23): I should mention that the BBC has a slideshow based on the exhibition. It doesn't have as much material, but it does have nice big versions of some of the included artwork. Plus, kinda depressing classical music.

    Eyes of a hominid

    I regard this one as unfinished, but I very much like the way the eyes have turned out, so I cropped it. Watercolors and gouache on an Academie pad.

    KNM-ER 406 and KNM-ER 3733, oblique view

    More little sketches. This is a famous pair. Richard Leakey and Alan Walker used KNM-ER 3733 (Homo erectus) and KNM-ER 406 (Australopithecus boisei) to illustrate the coexistence of at least two hominid species around Lake Turkana in the Early Pleistocene.

  • Profile: Paleo artist Viktor Deak

    Sun, 2009-06-14 14:30 -- John Hawks

    On the occasion of the Lucy exhibit going to New York, Donald McNeil, Jr., profiles artist and reconstructor Viktor Deak. Deak's 78-foot mural of human evolution is part of the exhibit.

    The article gives a nice short picture of Deak, what it takes to be trained as a paleo artist (hint: lots of anatomy), and his working environment. Deak's website has photos of a lot of his work. I especially like the way McNeil's article describes the artist-scientist interaction:

    Picasso never had to explain that his mistresses weren’t actually cubic, but Mr. Deak has taken grief over as little as a flexed knee. One academic critic who saw his Lucy mural publicly boasted that he himself “had the good fortune to examine Lucy when she was in Donald C. Johanson’s lab in Cleveland, and I can assure you that the anatomy of the lower back, hips, feet and knee and ankle joints all provide clear evidence that those early hominids stood just as erect as we do.”

    Mr. Deak replied on the same Web site that he knew perfectly well that Lucy could stand up, but he had depicted her crouching because she was pulling away from a predator — the viewer. She was, he explained, protecting the baby in her arms and about to run off.

    I just think that's classic. The scientist (and you know you can guess who) wants an iconography. The specimen is its features, and the artistic representation should lay those features out for the viewer. It's like having all the stigmata in the right places on a crucifix -- the wounds tell the story. The artist, on the other hand, wants to express the individual beyond the features, a story to be conveyed by posture and gesture. It's a conflict -- with many stories to tell, only a few can make it into a museum display.

    A girl from India, via Flickr. Watercolors and watercolor pencils on pastel paper. It was a work in progress, and then stopped progressing, so I've moved on to other things.

  • Photoshop web colors

    Fri, 2009-06-05 19:55 -- John Hawks

    This is off the usual topics, but I mentioned once how poorly colors were coming out when I save sketchbook pieces as JPG. They look great in Photoshop, but saving as JPG mysteriously dulls all the colors. For the Termineander, I overcorrected the colors and got acceptable results.

    But I wanted to point to a post on Viget Inspire, The Mysterious “Save For Web” Color Shift. As with all things art, many people have noticed the problem ahead of me. The simplest solution is to set draft view to "Monitor RGB" (the lowest common denominator for the web) and forget the wonderful saturated colors that Photoshop managed to automatically get out of your scans. Sigh.

    You might guess: I'm working on illustrating the lactase persistence story.

  • Extinct marsupial lion in Australian rock art

    Tue, 2009-05-26 08:53 -- John Hawks

    Speaking of super-predators from the past, Natural History Magazine has a short article describing Australian rock art that may depict the extinct marsupial lion, Thylacoleo carnifex:

    Kim Akerman, an independent anthropologist based in Tasmania, says the painting unmistakably depicts a marsupial lion.

    It shows the requisite catlike muzzle, large forelimbs, and heavily clawed front paws. And it portrays the animal with a striped back, a tufted tail, and pointed ears.

    The image is described in a brief and readable report in the March issue of Antiquity.

    The Termineander

    The Termineander

    I took this on at the suggestion of a reader.

    Yes, it's a Geico caveman morphed into the ultimate robot assassin from the future. Well, you were wondering how they got all those cranial wounds, weren't you?

    Yes, by drawing a robot in colored pencils, I have become the ultimate high school art geek.

    No, I don't suppose "Neandernator" works quite as well.

Denisova

From a finger bone of an ancient human came the record of a completely unexpected population. My lab is working on the science of the Denisova genome.

The advent of agriculture caused natural selection to speed up greatly in humans. We're uncovering some of the ways that populations have rapidly changed during the last 10,000 years.
