Crows hold secrets about aliens?

The scientific community has just obtained long-standing evidence of doubt that birds belong to the corvid family, including crows and magpie, very intelligent. This discovery may reveal the brain activity of non-mammalian organisms, including alien life forms.

>>>The truth about people being the smartest

According to Nature Communications, two biological neurologists from the University of Tübingen (Germany) have discovered how the brain of the crow produces intelligent action when making similar, strategic decisions. like humans, although there is no common ancestor.

Researcher Lena Veit explained that many functions in birds are completely different from humans, due to their long evolutionary history that separates us from these direct descendants of dinosaurs. Crows and primates possess different brains, but the cells that govern the decision-making process are very similar. It is a testament to a general principle that reappears throughout the length of evolutionary history.

"Just like the solid aerodynamic conclusions drawn from the comparison of different structural wings of birds and bats, here, we can draw conclusions about the mechanism of action. The brain by understanding the similarities and functional differences of the brain regions involved in bird and mammal brains, " said Professor Andreas Nieder, co-author of the study.

The team discovered that, unlike most other birds, crows are extremely intelligent. They are even behavioral biologists called "feathered primates , " because they can be made and used (such as dropping peanuts on the way to car crunch, help split peanuts), capable of remembering a large number of places to eat (such as changing migration routes, avoiding going through places where individuals in the herd were killed or killed) and up plan on herd behavior based on the expression of other members in the herd.

This level of superior intelligence surprised the researchers, because the bird's brain is fundamentally different from mammals, including primates.

In an experiment to test brain physiology for the crows' intelligent behavior, the team trained crows to perform memory tests on computers. These birds are shown a picture and must remember it. Not long after that, they had to pick one of the two photos (one identical and one completely different from the original image) that appeared on the touch screen with the selected cell.

Sometimes the test law is to choose the same image, sometimes choose a different picture. However, the crows are able to complete both tasks smoothly, showing a high concentration and mental activity, which only exists in a few animals, including humans.

When observing neurological activity in the brain region of nidopallium caudolaterale associated with the highest level of awareness in birds, the researchers found that a group of neurons that respond to crows must choose the same picture, while another group of neurons always responds when they make a request to choose a different picture.

Through observing neuronal activity as above, researchers can often predict exactly what crows are meeting the requirements even before they make a choice.
