There is an absolute gem of a post over at the Seforim Blog by Dr. Marc Shapiro. It discusses the newly released writings of Rav Kook concerning evolution and the historicity (or ahistoricity) of the early parts of the Torah, and the views of various Rishonim on such topics as the scientific accuracy of various prophecies, the lifespans in the Torah, and the general idea of the Torah communicating theological messages that are cloaked in then-contemporary beliefs. Make sure to read the footnotes too!
