Anthropology as a dog side-effect skill

Social Cognition in Dogs, or How did Fido get so smart?. This you know: Domesticated dogs seem to have an uncanny ability to understand human communicative gestures. If you point to something the dog zeroes in on the object or location you’re pointing to (whether it’s a toy, or food, or to get his in-need-of-a-bath…

Tiny dogs are freaks of evolution

Sometimes scientists report on research which clarifies what we already know. ‘Survival of the Cutest’ Proves Darwin Right: The study, published in The American Naturalist on January 20, 2010, compared the skull shapes of domestic dogs with those of different species across the order Carnivora, to which dogs belong along with cats, bears, weasels, civets…

Dogs adapting to urban ecologies

A friend pointed me to this fascinating article about stray dogs in Moscow: … It has become a symbol for the 35,000 stray dogs that roam Russia’s capital – about 84 dogs per square mile. You see them everywhere. They lie around in the courtyards of apartment complexes, wander near markets and kiosks, and sleep…

Dog selection

Tracking footprints of artificial selection in the dog genome: The size, shape, and behavior of the modern domesticated dog has been sculpted by artificial selection for at least 14,000 years. The genetic substrates of selective breeding, however, remain largely unknown. Here, we describe a genome-wide scan for selection in 275 dogs from 10 phenotypically diverse…

The dog as pig

There’s been some buzz over a recent paper, mtDNA Data Indicates a Single Origin for Dogs South of Yangtze River, less than 16,300 Years Ago, from Numerous Wolves. This is tracing the maternal lineage, and suggests that that lineage is most diverse in southern China (just as human lineages tend to exhibit the most diversity…

The dog as rat

Speaking of Richard Dawkins, he’s back to science, in this case an excerpt from his new book, The Greatest Show on Earth: The Evidence for Evolution: The evolution of the dog, then, if Coppinger is right, was not just a matter of artificial selection, but a complicated mixture of natural selection (which predominated in the…

We know that dogs can read human faces, it turns out that babies can infer the meaning of different dog barks: New research shows babies have a handle on the meaning of different dog barks – despite little or no previous exposure to dogs. Infants just 6 months old can match the sounds of an…

Genetic closeness != behavioral closeness

Sheril’s post, Chimpanzees Are NOT Pets!, is good. She notes: 1 Chimpanzees are wild animals. Animals that make good PETS like dogs and cats, have been domesticated for [thousands] of years. There has been selection on them against aggression, which is why a dog, unlike a wolf, will not automatically tear you to pieces. Anyone…
