If so, there may have been originally more than one ancient domestication event for dogs as there was for domestic pigs. One theory is that domestication occurred during one of the five cold Heinrich events that occurred after the arrival of humans in West Europe 37 000, 29 000, 23 000, 16 500 and 12 000 YBP. The theory is that the extreme cold during
Origin of the domestic dog which can be an indicator of travel. The archaeological record shows dog remains dating over 15,000 YBP in Western Eurasia, over 12,500 YBP in Eastern Eurasia, but none older than 8,000 YBP in Central Asia. The study proposed that dogs may have been domesticated separately in both Eastern and Western Eurasia from two genetically distinct and now extinct wolf populations. East Eurasian dogs then made their way with migrating people to Western Europe between 14,000-6,400 YBP where they partially replaced the dogs of Europe. Two domestication events in Western Eurasia and Eastern Eurasia has recently been found for the domestic
