Topic 2 [article]: Lokiarchaeum. Read about Lokiarcheum in the article by Yong (2)* and/or the article by Zimmer (3)*. Both articles describe recently discovered evidence about a previously unknown organism. Then, address the following questions:

• (a) Lokiarchaeum may be a “transitional form” between archaea and eukarya. What evidence suggests this?
• (b) Describe one way that this relates to this week’s lesson.

The following articles are the basis for this week’s discussion on the Cell, Lokiarchaeum, and rRNA
