Are the Purépecha of South American origin ?

by xskramx2

ive heard the purepecha are decedents of a chichimec tribe, but why didn't the speak nahuatl?..does that prove a south american origin?

how come there mythology and culture differs from the rest of Meso america?

Are the current inhabitants of michoacán descendants of the purepecha ?
