Please read the following article from the NY Times, “Under the Sea, A Missing Link in the Evolution of Complex Cells” and then answer the following questions in your own words:
1) The article begins by discussing the types of cells that biologists have thus far discovered. Compare and contrast the types of cells and basic characteristics of Eukaryotes, Archea, and Bacteria, called the three domains of life that represent the three types of cells currently recognized by biologists.
2) Why is the newly discovered cells described in the article so different from the currently recognized cells? Why do the authors refer to these cells as “transitional forms” or “a missing link” in the evolution of more complex cells like our own?
3) What is one of the roadblocks to studying these newly discovered types of cells?
