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.

Reply to comment by __System__ 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
