The New World wolves did not show any gene flow with the boxer, dingo or Chinese indigenous dogs but there was indication of gene flow between the Mexican wolf and the African basenji. [13] All species within the genus Canis, the wolf-like canids, are phylogenetically closely related with 78 chromosomes and can potentially interbreed. [100]

A California gray wolf, dubbed OR 85, in 2023. The wolf was fitted with a satellite collar to help the California Department of Fish and Wildlife track the state's burgeoning wolf population.
In 2023, a genomic study indicates that eastern wolves have evolved separately from grey wolves for the past 67,000 years and had experienced admixture with coyotes 37,000 years ago. The Great Lakes wolves were the result of admixture between eastern wolves and grey wolves 8,000 years ago.
Today, the last wild populations, totaling about two dozen animals, are clinging to existence on two federal wildlife refuges in eastern North Carolina. Takeaways from AP’s reporting on efforts ...
