They sequenced a 368 base pair fragment from the mitochrondrial genome and then compared it to sequences from ancient dogs, as well as to sequences from modern dogs, wolves, and coyotes.
Phases consist of multiple iterations — distinct sequences of activities with a base-lined plan and valuation criteria resulting in a release of artifacts (internal or external).
