Besides, no Darwinist has ever tested whether the centriole is actually a functioning turbine.
As an aside, it is probably more true that his thesis is based on the assumption that the centriole is a "designed object".
Basically his theory is based on intelligent design because he posits that the centriole is a system rather then a set of partially independent parts.
Wells makes clear in the paper that his assumptions are based on the thesis that the centriole is a designed object, like a machine, and should be studied as one.
In the middle of the centrosome is a minute body called the centriole, and surrounding this is a clear spherical mass known as the centrosphere.
Case in point – Wells '"paper" on centrioles, where he describes centriole structure, then describes the structure of a rotor-driven turbine … end of story … it's a hollow argument.
However, we have no experience of anyone designing a centriole.
If the centriole looks like a designed turbine (ones that humans make), then the design inference is strong (we have direct experience of an intelligent agent having designed something like it).
The centriole looks like a turbine (that we design).
The role of the centriole is poorly understood, but it is thought to play an important but not indispensable, role in aligning and separating chromosomes during cell division.
