I read somewhere that this breed of goat is the origin of the word "scapegoat". Does anybody know if that is true?
I highly doubt it. The earliest references to scapegoat I know of are in the Torah, the five "Mosaic" books in the Judaic/Christian Canon, written around 2000 BC (some scholars think the 6th century). The scapegoat would be a goat loaded with the symbolic sins of the community and sent into the wilderness to die.
