Canaan, Grandson of Noah

A new solution to why Canaan (not Ham) was cursed.

Does the Supplementary Hypothesis explain the existence of a fourth son that found his way back into Pirkei de-Rabbi Eliezer and the Quran?

Including a close look at how the description of the Canaanite lineage was constructed (Gen 10:15-18)

Noah learns of the sin of his youngest son, (Ham), and yet curses Canaan (his grandson); is Canaan Noah's youngest son? Contrasting traditional and critical approaches.
