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).
阶段由若干迭代组成——依照基本计划和评价标准的不同序列的活动会致使工件的发布(内部或外部的)。

Influence of neighboring base composition on nucleotide substitution bias was observed in the sequence of nuclear pseudogenes and chloroplast non-coding and coding sequences.
