Clovis points

Even though Clovis points, spear points with longitudinal grooves chipped onto their faces, have been found all over North America, they are named for the New Mexico site where they were first discovered in 1932.

(E) While Clovis points are spear points whose faces have longitudinal grooves chipped into them, they have been found all over North America, and named for the New Mexico site where they have been first discovered in 1932

The purpose of while is to express a CONTRAST. In E, whose faces have grooves and they have been found are not contrasting ideas, so while is being misused.

To be more clear on this,is there any difference between while/even though/although in GMAT?
I believe that each one is used to show a Contrast; Hence, all are replaceble.
