Or convergence. Cmon really?

There's already some genetic evidence that eukaryotic cells may descend from archea, so it makes sense they would want to find supporting evidence in the morphology of the cells. Science exists to study these questions afterall.

Really? I guess I don't agree.

With what part?

That a cytoskeleton could only evolve once.

I never stated that though. Just that this is more supporting evidence adding on to the pre-existing evidence that eukaryotic cells may descend from archea.

In convergent evolution, the structures serve the same function but came to that function through different means. Like the wings of an insect, bird and bat allow for flight but the wing structures are all different and evolved independently. In this case they did not just find a cytoskeleton, it’s actin, same as what eukaryotes have. It is the same structure and serves the same function. So these are most likely homologous structures.

Analogies provide the sensation of understanding but without prediction.
As scientists, all of you, how much are you invested in function?
