«Archaea resemble bacterial cells in size and shape but their cell cycle events — such as division and DNA replication — are a hybrid between eukaryotes and bacteria.»

These findings suggest that prions predate the evolutionary split between eukaryotes and bacteria about 2.3 billion years ago.

As Thattai and his colleagues Buzz Baum and Gautam Dey of University College London explain in their paper, that uncertainty has stemmed in large part from the lack of known intermediates that bridge the gap in size and complexity between prokaryotic precursors and eukaryotes.

But no detectable intermediates between ancient, single - celled life and early eukaryotes exist, making it nearly impossible to reconstruct the order of evolutionary events.

Although scientists generally agree that eukaryotes can trace their ancestry to a merger between archaea and bacteria, there's been considerable disagreement about what the first eukaryote and its immediate ancestors must have looked like.
