A fox raised in captivity might learn to be gentle. A dog who was abused might lash out. Behavior: it’s complicated. There has been great interest in the selective breeding of … Continue reading Foxy Behavior: how a Russian fox farm uncovered the basis of canine domestication
Dogs are “man’s best friend,” but how long have they been our four-legged companions? A recent study suggests that dogs and humans may have formed close relationships as early as 6,000 years ago — a relationship that involved humans feeding the dogs, but ended with the dogs being sacrificed. Canine remains from this era have been uncovered before, but this study adds 26 more specimens … Continue reading Dogs and humans were buried together in 6,000-year-old graves
In an exciting step forward, dogs with Duchenne muscular dystrophy (DMD) were treated with the CRISPR genome editor to restore production of the missing protein responsible for the disease. After more studies to prove it is safe and effective long-term, this has the potential to move into clinical trials as a DMD therapy. “[The dogs] showed obvious signs of behavioral improvement – running, jumping – … Continue reading Dogs with muscular dystrophy receive CRISPR treatment: What does this mean for humans?
by Katherine J. Wu The pets in our households are all descendants of wild animals, many of which still run free today. But dogs, cats, and rodents are all domesticated to varying degrees, with a wide range of consequences for their behavior and genetics. To understand the nitty gritty of this, let’s get some terminology out of the way first. When we discuss domestication, we’re … Continue reading You Asked: How are pets different from wild animals?
A new study has compared the brains of dogs and cats and found cats wanting. Scientists counted the number of neurons in the cerebral cortex of brains and found that dogs have more than double the number of neurons of a cat. While this doesn’t immediately rule that dogs are the smarter species, it does suggest they have a higher capacity for learning. Continue reading Dog owners rejoice! Dogs could be smarter than cats
