Here we analyze 105 whole mitochondrial genomes from the main clade of gray wolves within an approximate Bayesian computation framework to test for the number of times wolves colonized North America from Eurasia, and date colonization(s). We find that the mitogenomes of all living wolves in North America, including Mexican wolves, derive from a single colonization event from Eurasia that expanded its range into southern North America before the Cordillerian and Laurentide ice sheets fused in the Last Glacial Maximum, approximately 23KYA. This is more recent than expected based on the fossil record, suggesting that there were earlier colonizations that left no descendents.
