Dew-claws in wolves as evidence of admixed ancestry with dogs
Vestigial first toes (dewclaws) on the hind legs are common in large dog (Canis lupus familiaris) breeds but are absent in wild canids, including wolves (Canis lupus). Based on observational criteria, dewclaws in wolves have been generally regarded as a clue of hybridization with dogs, although this...
