nutshell

In 1996, Lehigh University professor of biochemistry, Michael Behe, published his first book Darwin’s Black Box, which famously advanced the concept of irreducible complexity (IC) to prominent status in the conversation of design in biology. In his book, Professor Behe described irreducible complexity as: A single system which is composed of several interacting parts that contribute to the basic function, and where the removal of any one of the parts causes the system to effectively cease functioning.

In illustrating his point, Behe used the idea of a simple mousetrap — with its base and spring and holding bar — as an example of an IC system, where the removal of any of these parts would render the mousetrap incapable of its intended purpose of trapping a mouse. Further, he provided examples of biological IC systems; each one dependent on several distinct parts in order to accomplish its task. Behe’s point in all this was that ALL the parts of the mouse trap are simultaneously necessary in order for a mousetrap to trap mice. And in a biological sense, if critical functions require several parts, then those functions would not occur until the various parts became available.  Read More

There must be an error on the Comlexity Cafe website as to when M. Behe published his first book. I always thought it was 1997 but it can't be 1985. M. Denton must've published his book closer to this date that inspired Behe to do research and write the book later on... much later... I think...J-Mac

I noticed that Dr Liddle had spent some time on UD recently, perhaps she'll stop by and argue that there is nothing semiotic in the cell.Upright BiPed

The 'Go to Top' thing is a mystery to me. I do not see it on any of three computers using four different browsers - or my phone. I'll research it.Upright BiPed

Great article and great website. I love the name "Complexity Cafe" and the art. The "go to top" button is slightly annoying but that can be fixed. Here's something I wrote in the Lee Spetner's thread regarding the design of the human eye. I think it's relevant here because the irreducible complexity of the eye is especially striking. Minor corrections added.
A close look at the retina reveals something that no stochastic BS can explain. The photoreceptors in the retina are grouped in a center-surround or radial design. Pairs of receptors in a group are then wired with retinal ganglion cells in such a way as to detect the movement of light in a very specific direction across the detector formation. The timing of the firing of the cells is extremely precise. The signals created by the retina are then encoded (using rank-order encoding) and sent via the optic nerve to the visual cortex for decoding and processing. Cortical timing mechanisms decode about 1 million signals from the optic nerve into over 200 million new signals representing different events of different primary colors and amplitudes. But this is not all. Amazingly, the design of the retina is such that one cannot see anything unless the eye is moving. We lose our ability to see if our eyes are immobilized with muscle paralyzing drugs. This is the reason that there is special circuit in the cerebellum that continually moves the eyes in tiny jerky motions called microsaccades. This happens even when we fixate our eyes on a dot. We would not be able to see without the saccades. The point is that one cannot design a retina without also designing the decoding/processing visual cortex and the cerebellar saccadic eye system. This is another example of Behe’s irreducible complexity. My advice to all is simple. All Darwinists are either stupid or lying through their teeth. Don’t believe anything that comes out of their mouths. Don’t let the jackasses do your thinking for you. Do your own thinking.
PS. The semiotic theme is unmistakable.Mapou

It's a potentially a nice site, except for the genius web designer who came up with a brilliant idea to splash a big ugly black rectangle "Go to top" right in the middle of the main text column. Did s/he ever hear of Home key on the keyboard which does that just fine without blotting the text. I can't comment much on the articles there since I couldn't watch that page for more than 30 seconds.nightlight
