Study Shows That Crows Are Much Smarter Than We Ever Imagined

Anyone who has ever had a run-in with a crow knows that they are quite intelligent. But a new study released in Science proves that they may be even smarter than we think. According to researchers, crows and other corvids possess primary consciousness—something that, until now, only humans and some primates were thought to have.

Crows have already proven themselves to be great problem solvers and can get quite creative, but this new discovery could change the way we think about the evolution of animals. So what exactly is primary consciousness? Also known as sensory consciousness, it’s a term that refers to the ability to put together memories and observed events to cultivate an awareness of the present and immediate past. For instance, as a child, we may have put our hand near a flame and gotten burned. Remembering this painful feeling taught us not to repeat the same action the next time the opportunity presented itself.

How did the researchers measure the cognitive abilities of crows? They worked with two carrion crows and trained them to signal whether or not they saw a coloured marker on a screen by moving their heads. Unequivocally throughout the tests, the crows showed that they could reliably signal whether or not the colored markers appeared. At some moments during the test, the markers were so faint that they were barely perceptible. In these cases, sometimes the crows still signalled the marker and in others, they did not. That’s where their subjective perception came into play — via My Modern Met

Rarest dog breed in the world is still alive (and singing) in the wild

The New Guinea singing dog is one of the oldest and rarest dog breeds in the world. It’s believed only 200 to 300 specimens are alive today, all of which are found in conservation centers. None have been seen in the wild since the 1970s. But a new genetic study found that another rare dog breed, the Highland Wild Dog, is essentially the same breed as the New Guinea singing dog, showing that this population isn’t actually extinct in the wild — via ZME Science

Urban foxes may be self-domesticating in our midst

In a famous ongoing experiment started in 1960, scientists turned foxes into tame, doglike canines by breeding only the least aggressive ones generation after generation. The creatures developed stubby snouts, floppy ears, and even began to bark. Now, it appears that some rural red foxes in the United Kingdom are doing this on their own. When the animals moved from the forest to city habitats, they began to evolve doglike traits, new research reveals, potentially setting themselves on the path to domestication — via Science
