Reply to comment by Gayiaj in A complex cytoskeleton, previously only observed in eukaryotic cells, is now found in a new species of archaea from the Asgard group, supporting the theory that eukaryotes evolved from Asgard archaea by vtj
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?
