The evolutionary tree (from whether dogs are derived from a single wolf lineage

Question

The evolutionary tree (from whether dogs are derived from a single wolf lineage or Vilà et al. 1997) tells us several, but it does not tell us where in the world the most recent wolf ancestors of today’s various dogs lived. Evolutionary biologists have continued to study the geographic origin of dogs. The two figures on the next two pages show more recent research on dogs

1. Did dogs derive from a single wolf lineage or from several? Explain your answer, referring to the phylogenetic trees in this document.

2. What is the geographic origin of dogs and how does the work by Freedman et al (2014) supply an answer to this question?

3. Read the Conclusions of the article linked with the second figure. Why do the authors think it is important to study dog phylogeny?

Explanation / Answer

A study in the current issue PLOS GENETICS suggest that instead ,dogs and gray wolves share a common ancestor in an extinct wolf lineage.
