Stephen Jay Gould
gregladen | May 16, 2017Every single regular reader of this blog has read or intends to read Stephen Jay Gould's The Panda's Thumb: More Reflections in Natural History. I just noticed that the Kindle version of it is available for $1.99, and I assume this is temporary. I already had the book on dead-tree matter, but I picked this up because ebooks are searchable! You will want one two.
Every single regular reader of this blog SHOULD want to read, or should have already read, Mary Doria Russell's excellent binary set including The Sparrow: A Novel and Children of God. (The Sparrow is first, COG second.)
Right now…
gregladen | April 8, 2015Much is being made of Brontosaurus. Brontosaurus is a genus name for a large dinosaur, known to watchers of “Land Before Time” as “Long-Necks.” That generic name dates to the 19th century, but in the early 20th century it was eliminated as a proper Linnaean term and replaced with Apatosaurus. This made us sad. Most people discover dinosaurs and learn all about a select handful of the iconic ones, including Brontosaurus, then later learn that Brontosaurs is a bogus name. And become sad.
But perhaps this sadness is all for naught, because a very recent study seems to require the resurrection…

A red panda (Ailurus fulgens, left, photographed at the Bronx Zoo) and a giant panda (Ailuropoda melanoleuca, right, photographed at the National Zoo).
As the paleontologist Stephen Jay Gould observed in one of his most famous essays, the thumbs of giant pandas (Ailuropoda melanoleuca) are nothing at all like the large digits on our own hands. Their accessory "thumbs", visible on the surface as a differentiated part of the pad on the "palm" of the hand, are modified sesamoid bones derived from the wrist. They are jury-rigged bits of anatomy which cast nature as an "excellent tinkerer, not…
gregladen | December 22, 2009This post started out as a comment that would have gone here (but would have done just as well here). But it became sufficiently long and possibly interesting that I figured it would make a good, if somewhat rough, blog post.
The presumption being examined here is that humans are divisible into different groups (races would be one term for those groups) that are genetically distinct from one another in a way that causes those groups to have group level differences in average intelligence, as measured by IQ. More exactly, this post is about the sequence of arguments that are usually made when…

A month ago Larry Moran made reference to Fern Elsdon Baker's new book, The Selfish Genius: How Richard Dawkins Rewrote Darwin's Legacy. Moran was a bit disappointed by the previews, his pet hobby-horse being the revolutionary impact of the neutral theory of molecular evolution, while Elsdon-Baker seems rather fixated on the potential of Neo-Lamarckism, especially epigenetics. Well, I've read the book, and Larry Moran would probably be disappointed, though she mentions Stephen Jay Gould and pluralism a bit, there's really very little engagement with the 20th century debates in evolutionary…
emjohnson | July 14, 2009On this day 76 years ago (July 14, 1933) a sterilization law was passed in Nazi Germany, known as Gesetz zur Verhütung erbkranken Nachwuchses (Law for the Prevention of Genetically Diseased Offspring). Any German was a target if they were found to be suffering from a range of perceived hereditary ailments, such as congenital mental deficiency, schizophrenia, manic-depressive insanity, epilepsy, Huntington's chorea, blindness, deafness, any severe hereditary deformity or even severe alcoholism. Official pronouncements insisted that these individuals were a drain on the German people, both…
