Likelihood mapping analysis off all 142 canid sequences clustered into four groups.

<p>Upper panel shows the distribution pattern of all quartets and the lower panel depicts the fraction of each occupied region. Quartets situated in the centre part of the triangle support a star-shaped sequence evolution whereas quartets in the three corners support resolved topologies, respectively. A) Likelihood mapping pattern when clustering the sequences into Altai dog, dogs, wolves and coyotes. B) Likelihood mapping pattern when sequences were clustered as follows: Altai dog, dogs, wolves and prehistoric New World canids taken from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0057754#pone.0057754-Leonard1" target="_blank">[23]</a>–<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0057754#pone.0057754-Leonard2" target="_blank">[24]</a>.
