Researchers Found "Dog is Smarter than Cat"

Dogs turned out to be smarter than cats because of their friendly character turned out to help the development of the brain so that its size became larger.

As reported by the Telegraph, the research results are expected to end the debate among pet lovers.

The experts at Oxford University suggests, for millions of years of dog intelligence has evolved so that are in levels higher than the cat.

During this assumes that there are cats smarter than dogs because it does not need much attention. However, researchers have found that cats brain are smaller because they are animals that are less social.

Scientists for the first time succeeded in mapping the evolutionary history of various groups of mammalian brain in a period of more than 60 million years. The study also identifies large variations in changes in the brain.

They found no link between brain size animal with his whole body as well as the level of social activity.

This study analyzed the available data on brain and body size of over 500 species of mammals living and fossil.

Monkey brain during this period grew the greatest followed by horses, dolphins, camels and dogs.

The study found that the group of mammals with a relatively large brains tend to live in stable social groups.

Brain solitary mammals such as cats, deer and rhinos, grew much more slowly during this period.

The study was published in the Proceedings of the National Academy of Sciences.

Dr Susanne Shultz, who led the research said: "The dog was always regarded as a more social animal, while the cat wanted to be alone. Interactions have probably beneficial for the brain, as well as in other species, such as ourselves."

"We're more social than monkeys and apes, and this joint has the ability to help humans dominated the planet."

These studies overturn the old belief that brain size has increased in all mammals. Only groups of highly social species that has increased rapidly than solitary species.
