A column in The Roanoke Time 10/6/02 on dog history (with some inconsistent
information re dog paleo-ancestry -- e.g., coyote genes have been identified
in Native American dog remains and Native Americans had dogs before
Europeans, as the Aztec example shows).
Interesting perhaps is the early reception of dogs claimed for Arabia:
"The first domesticated dogs appear to have originated in Central and North
Africa. About 10,000 years ago, the nomadic Berber tribesmen started to
supply other tribes along the Nile, in Cush and Egypt with hunting dogs
similar in appearance to the greyhound and Saluki. As the Egyptian
civilization expanded, the people traded with Arabia, receiving gold and gems
in exchange for grain and dogs."

(BUT NOTE: DNA evidence would suggest that like the horse -- but unlike the
cow, sheep, pig and goat -- the dog was domesticated in a wide variety of
locations, rather than descending from one or two discreet lines.)
