Our understanding of how domestication adjustments the neurobiology of a species could also be flawed, outcomes from a 60-year experiment to breed tame foxes recommend. The findings may even have implications for human evolution, declare researchers.

Normally, domesticated animals have smaller brains than their wild counterparts, however foxes raised in a Russian fox farm experiment in Novosibirsk haven’t adopted that development.
