It has been theorized that humans underwent some behavioural changes when the Eurasian wolf was domesticated, a "reverse" domestication (of man by wolf) or "convergent evolution". Supposedly, human-wolf cooperation created evolutionary pressure to organize , cooperate, and structure ourselves in big groups, things that wolves naturally do, but primates cannot. Of course the other effect was to turn the majestic grey wolf into a chihuahua.

This domestication happened in Eurasia between roughly 41,000 - 23,000 years before present (YBP). However, in another section of that Wikipedia article, it states that (from Origins and genetic legacy of prehistoric dogs):
Does anyone else see an inconsistency here? Is 7,000 years enough time for those wolf-like behaviours to develop in man? Or did convergent evolution only happen over the longer 20,000 year period, and only in those humans who formed a cooperative society with canines?
In other words, are there maybe exactly two subspecies of human: (1) those who passed through Eurasia, encountered and domesticated the Eurasian wolf, and underwent behavioural changes, and (2) those who did not?

The life of chimpanzees, especially their sociality, as revealed by the pioneering work of Jane GOODALL and others (GOODALL 1986;DE WAAL 1997) appears as a frightful caricature ofhuman egoism. Even in their maternal behavior, warmth and affection are apparently reduced to nursing and an occasional comforting hug; cooperation among group members is limited to occasional hunting episodes, or the persecution of a competitor, always aimed for one’s own advantage and executed with MACHIAVELLIAN shrewdness.

In 2020, the sequencing of ancient dog genomes indicates that the lineage of modern dogs in sub-Sahara Africa shares a single origin from the Levant, where an ancestral specimen was dated to 7,000 YBP.
