Outside of Shema and the Amidah, can someone explain the chronology of what sections of the Siddur service as we currently have them were added? E.g. was Psukei Dezimra added first? Blessings before / after Shema? Which ones?
Also, which tefillah was developed first - weekday Shacharit, mincha, etc.?
As a "bonus" to your answer, I'd greatly appreciate if you can find an online or book source that lists the "chronology" of the prayers that were added to the Siddur.
