A program that gets college students enthusiastic about the scientific theory of evolution

David Sloan Wilson has written some terrific articles on the topic of evolution. I recently ran across a 2005 article he wrote for PLoS Biology www.plosbiology.org titled "Evolution for Everyone: How to Increase Acceptance of, Interest in, and Knowledge about Evolution." The article explains the method by which Binghamton University has successfully infused its undergraduate curriculum with real-life applications of evolutionary theory. The EvoS program began in 2002. Here's the mission of EvoS:

The mission of EvoS is to advance the study of evolution in all its manifestations, including all aspects of humanity in addition to the biological sciences. Many organizations and websites promote the study of evolution, but EvoS is unique in two respects.

• EvoS is based on the realization that evolutionary theory will probably never be generally accepted--no matter how well supported by facts--unless its consequences for human affairs are fully addressed. Once evolution is seen as unthreatening, explanatory, and useful for solving life's problems, then it becomes not just acceptable but irresistable to the average person (see the tutorial for more).

• EvoS makes a connection between evolutionary theory and the unification of knowledge, which has always been the goal of a liberal arts education and contemporary efforts to integrate across disciplines. The same kind of unification that took place in the biological sciences during the 20th century is now taking places for the human behavioral sciences and humanities--but is not yet reflected in the structure of higher education. EvoS is the first program to diagnose this problem and comprehensively provide a solution at a campus-wide scale.

David Sloan Wilson explains that the Binghamton program makes use of 50 faculty members representing 15 departments. The program was created based on the following assumption: "Evolution can be made acceptable, interesting, and powerfully relevant to just about anyone in the space of a single semester."

Orchids are back at the Missouri Botanical Garden

Once again the orchids are on display at the Missouri Botanical Garden. I snapped some photos or these incredible beings. After all, they are our cousins. Richard Dawkins estimates that animals diverged from the plant kingdom about two billion years ago. orchid1 I've written previously about Darwin's fascination with orchids here. For today, I will simply paste in a few new photos of these incredibly beautiful plants. I've posted many more of my photos of today's show at one of my public web albums at Picasa.

Another well-deserved attack on rationality

Why do we do the things we do? Why did you propose that woman, for instance? Or why did you accept a job offer from that man? The January 29, 2009 edition of Nature (available online only to subscribers) takes a look at this question in an article by Mark Buchanan titled "Secret Signals: Are People's Interactions Driven by a Primitive, Not Linguistic Type of Communication?" Scientists have determined that there is a second channel of human communication that (often) acts in parallel with our rational thinking and verbal communication. It's difficult to pin down power and scope of this non-linguistic ability, however. Recently, computer scientist Alex Pentland has started using wearable electronic devices in order to study our ability to communicate using non-linguistic behavior. It is Pentland's aim to try to assist organizations to make better use of their personnel based upon this ubiquitous and powerful hidden communication. Many people resist the idea that many of our choices are not determined by "conscious intentions and deliberate choices." It's time to stop resisting, however. For example, our behavior is highly determined by our social context rather than our innate "character." On this topic I've often recommended an excellent book titled The Person and the Situation, by Lee Ross and Richard Nisbett. See also, this earlier DI post titled "Laughing at not funny things, and the limits of introspection."

Creationists blather their way through Darwin Day

If you visit Ken Ham's creationist site, you'll see an article titled, "Did humans really evolve from ape-like creatures?" Here's a key concern raised in this article:

Perhaps the most bitter pill to swallow for any Christian who attempts to “make peace” with Darwin is the presumed ape ancestry of man.

It's difficult to believe the ignorance displayed by this sentence. Why can't creationists understand that not only did humans evolve from other ape-like creatures (the scientific evidence is abundant and irrefutable), but that humans are apes. Check the features listed here:

The similarities can be seen throughout our bodies. For instance, humans and the African apes all lack external tails and have hands with a thumb that is sufficiently separate from the other fingers to allow them to be opposable for precision grips. Humans are also sexually dimorphic--males are 5-10% larger on average and have greater upper body muscular development. Like chimpanzees and bonobos, we are omnivorous. We kill other animals for food in addition to eating a wide variety of plants. Internally, our bodies are even more similar to the great apes. We have essentially the same arrangement of internal organs and bones. We share several important blood types. We also get many of the same diseases.

What if there were animals that were genetically close to modern humans, but startlingly different?

What if there were animals that looked very much like modern human animals and almost identical genetically, yet they differed from us in notable ways? Would their discovery shock and horrify people? Quite likely. Wouldn't it also make many people start thinking deeply about the fact that modern humans themselves are animals? You'd hope so. Wouldn't this discovery make us intensely curious about our own origins? Remains to be seen. What follows is a true story. The evidence is overwhelming that large numbers of Neanderthals roamed Eurasia for 200,000 years. The evidence is also clear that Neanderthals differed from the modern humans in genetically small but socially and physiologically significant ways. This incredible story can be found in the October 2008 edition of National Geographic, in an article entitled "Last of the Neanderthals." This article is a must read article for anybody who wants to peer into the not-so-distant past in order to learn about his or her bipedal cousins. The article is filled with incredibly lifelike modeling of the Neanderthals. It is also filled with detailed information about Neanderthal physiology, as well as clues to Neanderthal lifestyle.
