Brain scans find dogs and humans respond to voices in a similar manner

A new study, which focused on brain imaging, found that the brains of dogs and humans process emotion and voices in a similar manner.

For the study, 11 dogs and 22 humans underwent fMRI scans, and while they were being scanned, sounds were played for them. The brains of both humans and dogs responded to sounds made by their own species in similar ways.

“What makes us really excited now is that we’ve discovered these voice areas in the dog brain,” said Attila Andics, comparative ethologist, Eötvös Loránd University in Hungary, lead author of the paper. “It’s not only dogs and humans. We probably share this function with many other mammals.”

This is also interesting because of the fact that humans and dogs share a common ancestry a hundred million years ago, meaning that the brains of other mammals that humans share an ancestry with may work in a similar manner.

“It’s not a surprising finding, but it’s an important finding,” said Marc Bekoff, who is a cognitive ethologist and author as well.

    [@Darcy] You’ll be even more chagrined to KNOW that dogs and whales also share a common (much more recent than the human-dog “fork”) ancestor. Darwin’s theory actually is more than 150 years old and is an attempt to explain what we SEE. So far, it does so better than any other, testable theory.

    Humans and dogs have such an immensely long history together, it is no surprise that we communicate so similarly and well.

    @Ashraf – hahaha! Now I know why you call yourself “Boss” but, even though I haven’t had the pleasure of meeting you, I can prove you wrong: There is NO WAY you spent as much time at computer keyboards as you obviously have… not with itsy-bitsy T-Rex arms, anyway. :-b

    There are far too many gaps in the fossil record, even now more than a century after Darwin’s book and hundreds of millions spent searching, for me to blindly believe men and dogs shared a common ancestor. Darwin himself said that hundreds if not thousands of transitional species would have to exist, yet each species appears in the fossil record out of nowhere. Suddenly there and sometimes just as suddenly gone.

    Most evolutionists can name dozens of transitional species, but nobody has ever found an unbroken chain from one species to another. Pointing at major similarities between two different fossils that also have major differences doesn’t show how they changed over time.

    To this date, that part of Darwin’s theory remains unproven. The remaining parts of his work, describing adaptive change, founding several of the eco-sciences, etc, are brilliant but I think large scale evolution has far too many holes.
