Are we humans simply remodelled apes? Chimps with a tweak? Is the difference between our genomes so minuscule it justifies the argument that our cognition and behaviour must also differ from chimps by barely a whisker? If “chimps are us” should we grant them human rights? Or is this one of the biggest fallacies in the study of evolution? NOT A CHIMP argues that these similarities have been grossly over-exaggerated - we should keep chimps at arm’s length. Are humans cognitively unique after all?

Genetic study confirms: First dogs came from East Asia
In NOT A CHIMP I discuss the evidence that humans have self-domesticated. One animal model of the process is dogs. The suggestion is that, rather than humans cultivating wild wolves and domesticating them, the wolves did it themselves through a long process of commensalism around early human encampments. But where on the globe did that process begin and what type of wolf best represents the dog ancestor? There is a long-running battle, based on genetics and archaeology, between researchers who believe the Middle East was the cradle of dog domestication and those who prefer East Asia. Here, Peter Savolainen, from Sweden, presents strong genetic evidence that all dogs emanated from an area of wolf domestication in what they call the ASY region - Asia south of the Yangtze - in southern China. The article discusses no dates and does not debate the commensalism versus purposeful selection argument for how dogs acquired their domesticated traits.
