gregladen | February 23, 2008Regarding the topic of design and in particular design, as a term in evolutionary biology, see "The "design" mistake" at Evolving Thoughts.
gregladen | February 23, 2008PZ Myers notes that Ken Miller is making a case for the term design in evolutionary biology. Miller simply claims that "design" comes from the usual, expected evolutionary processes (Natural Selection, etc.). PZ is not buying this bill of goods, and neither am I. One way to address this question might be to ask: "What would Darwin do?"
Darwin uses the word quite often in The Voyage (a text I'm closely examining these days) but with only one exception that I found (my search was not perfect) this is typically in connection with cultural things .... the design of a road, for instance. One…
gregladen | February 22, 2008In 1833, Darwin spent a fair amount of time on the East Coast of South America, including in the Pampas, where he had access to abundant fossil material. Here I'd like to examine his writings about some of the megafauna, including Toxodon, Mastodon, and horses, and his further considerations of biogeography and evolution.
In the vicinity of Rio Tercero...
Hearing ... of the remains of one of the old giants, which a man told me he had seen on the banks of the Parana, I procured a canoe, and proceeded to the place. Two groups of immense bones projected in bold relief from the perpendicular…

Google is funding work to ensure the Windows version of Adobe Systems' Photoshop and other Creative Suite software can run on Linux computers.
For the project, Google is funding programmers at CodeWeavers, a company whose open-source Wine software lets Windows software run on Linux. Wine is a compatibility layer that intercepts a program's Windows commands and converts them to instructions for the Linux kernel and its graphics subsystem.

gregladen | February 21, 2008The current edition of this fairly new web carnival is here. It's interesting.
gregladen | February 21, 2008"We were tossing around ideas about the size of the Galaxy, and thought we had better check the standard numbers that everyone uses. It took us just a few hours to calculate this for ourselves. We thought we had to be wrong, so we checked and rechecked and couldn't find any mistakes."
A team of Australian astrophysicists pulled some readily available data off the internet, ran it through a spreadsheet model, and re-estimated the thickness of the 100,000 light year wide Milky Way Galaxy. The previously widely used estimate was that the Galaxy was 6,000 light years thick, but this new estimate…
gregladen | February 21, 2008Plan B is, of course, inserting Christian Creationism into the Social Studies curriculum. This is disconcerting. Many otherwise perfectly rational and intelligent people think this is a good idea. It is not.
This sort of proposal is becoming more common now (this week) in editorials and other opinion outlets, with the defeat of the Wedge Strategy to water down the science standards in Florida. (This rebound effect occurs every time creationists are defeated.)
So, why is this not a good idea?
Social studies is a broad field of investigation that has many important goals. Like modern…
gregladen | February 21, 2008"The Wedge Strategy" refers to a document (the Wedge Document) developed by the Discovery Institute in 1998 and leaked by Tim Rhodes in 1999. It outlines a strategy to insinuate a specific subset of Christian Fundamentalism into the public education system. Although Wedge Proponents have denied this, the Wedge Strategy is still very much in use (more or less), so it is important for people interested in protecting our system of education from religious freaks to know about it. You can download a copy of it here (large PDF, 0.5 megabytes).

Thinking like an economist (about Parent-Offspring Conflict)
Published in 1974, this paper is arguably Bob Trivers 2nd most influential paper behind the paper describing reciprocal altruism... Because very few people read long blog posts, and the idea is to introduce these ideas to people that might not already be familiar, I'l go ahead and list the main points/finding, and then go into some brief discussion about ...

gregladen | February 20, 2008Everyone knows about Darwin's Finches, of the Galapagos Islands. But of course, Darwin made observations of birds throughout his travels on The Beagle. Here, I present a number of passages from The Voyage that include some of these observations.
Struthio Rhea
I will now give an account of ... the Struthio Rhea, or South American ostrich. This bird is well known to abound over the plains of Northern Patagonia, and the united provinces of La Plata. It has not crossed the Cordillera; but I have seen it within the first range of mountains on the Uspallata plain.... The ordinary habits of the…
gregladen | February 20, 2008A good trick in child psychology is to come to a "compromise" in which the child, not knowing any better, gets what they think they wanted but it really turns out to be cod liver oil after all. Florida creationists got their cod liver oil when the Florida School Board voted, with a worrisome 4-3 count, to accept the proposed science standards that actually use the word "evolution."
The word "evolution," however, is qualified as a "scientific theory." That's the compromise part. Creationists, like young children, can get certain concepts very wrong, and this is one of them. We often hear…
gregladen | February 20, 2008Despite having only a couple of beers, I'm a little fuzzy this morning, but I do want to give a short update last night's Cafe Scientifique at the Bryant Lake Bowl (sponsored by the Bell Museum of Natural History).
First, thanks to everyone for coming, and I'm truly sorry for those of you (Mike, Rob, Betsy, Chris, and countless others) who could not make it it. It was nice to have a sold-out 'performance' but not nice that people schlepped all the way to LynnLake in sub zero weather! But, in the end, you probably had more fun drinking and bowling than sitting listening to me.
