Chaser, Border Collie Knows 1022 Words

"In the age-old war between cats and dogs, canines might just have struck the killer blow. A border collie called Chaser has been taught the names of 1022 items - more than any other animal. She can also categorise them according to function and shape, something children learn to do around the age of 3.

Dogs have been bred to have such a large variety of differences in behavior the various breeds that they will make great sources of DNA sequences to use to identify genetic variants that cause their cognitive characteristics. Given that the breeds differ considerably intelligence comparing breeds (or even different dogs in the same breed) could turn out to be useful in identifying genetic variants that cause intelligence and behavioral differences.



Where does this lead? Breeding for even smarter dogs which can understand even more complex forms of human language. Dog DNA sequencing to discover genes that influence intelligence might turn up some intelligence-boosting genetic variants than even Chaser has. Identification of all these variants would give breeders a goal to shoot for: get as many of the variants as possible into the same litter of dogs.


Identification of intelligence-boosting genetic variants in other species could lead to genetic engineering to put some of those variants into dogs. Is a 70+ IQ dog within reach in, say, 20 or 30 years? Seems like it."
