What do these creatures have in common? One possibility–beautiful brains.
Whenever I yank meat from a lobster or crack a crab claw, one thought always pops into my head: these look like giant spiders. It doesn’t stop me from eating them (
Don’t believe me? There’s plenty of proof in the new, 800-plus page book, Arthropod Brains: Evolution, Functional Elegance, and Historical Significance by Nicholas James Strausfeld (Harvard University Press, 2012). The book looks at the structure of arthropod brains, their similarity to mammalian brains, and tells the stories of the scientists who worked (and are still working) to figure it all out.
Strausfeld, a professor and Director of the Center for Insect Science
at the University of Arizona, spans centuries telling the history of arthropod neuroanatomical discovery, beginning with the insect studies of the 17th century microscopist Robert Hooke. Hundreds of images, including drawings from the notebooks of the French naturalist Dujardin and Santiago Ramón y Cajal, described as the “founder of the neuron doctrine,” accompany the text. But for me, the highlights of the book are those beautiful slices of brain. Here’s a sampling of images, in the slideshow above.
