Origin of Life Refresher

In case anybody is interested in reviewing the class a bit, one of my earlier topics provided a very good summary of the first few weeks of class. The article, titled, On the origins of cells: a hypothesis for the evolutionary transitions from abiotic geochemistry to chemoautotrophic prokaryotes, and from prokaryotes to nucleated cells. discusses how life came about, the key differences between prokaryotes and eukaryotes, and through those differences infers the basis of their common ancestor and its corresponding characteristics.

While the article is fairly lengthy, its laid out well into specific sections if you're interested in particular topics such as chirality. Many of the figures will be familiar as similar ones were used in lecture. Additionally, all of the theories presented (and also challenged) are well-reasoned and supported with common evidence. I encourage you to skim through it--it's extremely well written!
