Jazz is not Blues and Blues is not Jazz.......

The two have obviously diverged but they come from the same place blues being a bit more ancient. Jazz frequently plays homage to blues as in Kind of Blue. But the intent of genres has changed so much that blues in particular is hardly recognizable. Jazz is now composed of numerous mini genres some of which are hardly recognizable as music. I can always listen to John Lee But the Art Ensemble of Chicago can get a bit tedious and I have to be in the mood and alone in the house. 

That Clarksdale clip pretty much defined the "real" Blues, and Jazz is still jazz; my ears tell me so. When I hear any of the classic Blues players from Clarksdale playing "On Green Dolphin Street" I might have a change of heart.

I notice nobody has mentioned "Ragtime", which is linked to Scott Joplin and Jelly Roll Morton who claims to have invented jazz.

It seems that what's called modern jazz has come a long way. While modern jazz borrows from many genres of music, I don't believe they are connected in a linear sort of way, like if we didn't have this we couldn't have that. Where does "Ragtime" come in;

Ragtime was a precursor of Jazz. Late 1800’s-early 1900’s.

RAGtime . Ragged rhythm : syncopation; the main defining characteristic of Jazz (the “swing”). Ragtime was not really Jazz in the strictest sense of the word since there was no improvisation to speak of . Players (Morton) would later incorporate improvisation along with other influences such as Blues and Jazz was born. No big mystery here as it is well documented.

The evolution of Jazz is linear; it builds on what came before. Same can be said of practically all art.
