What does Behe mean by a structure that is irreducible complex?
One of Behe’s arguments in regards to evolution being an idea of the past and something that needs to be discarded or thrown out, he bring up the concept of irreducible complexity. This idea presents thought that there are organisms that have a series of interacting parts that are so complex that if one part is not present then it is impossible for the organism to function. Therefore making the claim that the organism was creating all at once as a singular piece and that in turn it could not have evolved to state in which it is now. (Bull puckie if you ask me)
Is the mammalian ear irreducibly complex? Why?
The mammalian ear is not a irreducibly complex design because for some time now scientist have been explaining through the use of the fossil record, that the two bones that form the lower jaw of reptiles have evolved within us to serve as a functional part of our inner ear. It is because of this that we can see the functions or features can evolve and changes to meet the needs of these species that share them. This truly is natural selection at its finest.
Behe claims that the eukaryotic cilium as an irreducibly complex structure, arguing that the 9+2 pattern of microtubules is essential for the cilium to beat. Test this hypothesis scientifically.
In order to test this has hypothesis we would have to prove that without the 9+2 cell pattern, the cilium would not beat or function. Then we would not to prove the there are less complex cell pattern that produce the same result like the 9+1 or the 9+0 miller made mention of in the reading, By doing this we would have grounds that Behe’s argument had a great deal of holes.
Explain how blood clotting evolved.
Blood clotting evolved from the different components found in blood and tissue, it is from these components that you can find soluble proteins that when put together have a primitive blood clotting reaction that could dated back to the early invertebrates. This ability shows that this reaction was working within our ancestors and now is working within us. Doolittle (Haha nice name) then goes on to present the idea that it is because of gene duplications that we see this reaction still today. Because of how useful blood clotting is in our survival, natural selection has kept this reaction and also refined it so that is would work more effectively with in each species.
