It is interesting that while the ribosome is the cell's protein assembly plant, the ribosome itself is made of many proteins. How did evolution create this protein factory? The blind process would have needed proteins to build the factory, but from where could it get proteins if the protein factory was not yet built. Evolutionists aren't yet sure just how this occurred.
Another problem is that the ribosome is complex, and new research is revealing it to be even more complex than previously thought. As one researcher explained:
Scientists used to think that the ribosome made a simple two-stage ratcheting motion by rotating back and forth as it interacts with mRNA and tRNA. What we captured were images of the ribosome in intermediate stages between the rotations, showing that there are at least four steps in this ratcheting mechanism.
We suspect that the ribosome changes its conformation in so many steps to allow it to interact with relatively big tRNAs while keeping the two segments of the ribosome from flying apart. It's much more complicated than the simple ratcheting mechanism in a socket wrench.
If evolution weren't a fact one might wonder if it really is the essential, unifying idea upon which all of biology depends.
