Question

Are Bacteria or Archea ancestor of eukaryotes?

Answer 1

Technically speaking I’m pretty sure neither is true, but if this is a multiple choice or fill in the blank, then bacteria would likely be your best bet. All three domains came from the same common ancestor, later later the common ancestor that would create bacteria and the common ancestor that created both arches and eukarya diverged. Eukarya and archea are sister phyla, so according to the current tree of life they can’t be ancestors of eachother.

Answer 2

These findings inspired the hypothesis that the archaeal ancestor of eukaryotes was an unusually complex form with an elaborate intracellular organization. ... To begin with, a typical eukaryotic cell has a three to four orders of magnitude larger volume than most bacteria and archaea [3–5]
