Study says brain size of animals does matter

New York: Animal brain size estimates its problem-solving ability, says a study.

Species with large brains were more successful than species with relatively small brains, the study revealed.

“The results of this study provides important support for the claim that brain size reflects an animal’s problem-solving abilities and enhances our understanding of why larger brains evolved in some species,” said Sarah-Benson-Amram, assistant professor at the University of Wyoming in the US.

Species that are more social or live in big social groups are not necessarily better problem-solvers than those that live alone, highlighted the study.

The study represented a step forward in understanding the evolution of problem-solving in mammalian carnivores, researchers revealed in the study published in the Proceedings of the National Academy of Sciences.

Researchers tested 140 zoo animals from 39 mammalian carnivore species with a problem-solving task.

Animals such as river otters, wolves, bears, African wild dogs and cheetahs tried to open steel mesh “puzzle boxes” baited with food and adjusted to their body size.

The animals opened the puzzle box using a lever, and if they were successful, they received a food reward in the box.

Overall, 35 percent of animals successfully solved the puzzle, with bears as the most triumphant at completing the task 70 percent of the time. Meerkats and mongooses were the least successful.

Although these species also differed in body size, it was their brain size relative to how big they were that primarily influenced whether they solved the puzzle.

Variables such as the social group size for animals, their manual dexterity or work effort failed to predict success at opening the boxes, the study showed.(IANS)

He sees himself on the forefront of fighting climate change as a global shift to a vegan diet will cut food related GHG emissions by 70%.

Amit Tiwari, founder of Soul Burgers fast food chain of restaurants in Australia, prides on selling tasty burgers with no animal meat in them. A burger without cruelty to animals (assuming killing is cruelty) and good for the environment (meat production is one of the major factors for climate change) is certainly good for the Soul, a soul burger.

According to Soul Burger’s web site, plants are the future of meat! Although we make look at Amit and his Soul Burger joint as a fast food outlet, he doesn’t see it that way.  He sees himself and his burgers as leading a global movement in keeping animals out of slaughterhouses and off our menus. Plant-based foods also reduces the risk of chronic disease and are lower in calories than a typical meat burger.

Amit Tiwari also believes that he is selling more than burgers. He sees himself on the forefront of fighting climate change as a global shift to a vegan diet will cut food related GHG emissions by 70%. Every plant based burger helps save the planet!

If cruelty and climate change were not enough, Amit also believes that his burgers can eliminate poverty. How? Well, by shifting to plant based foods, we cease contributing to inflated grain prices used to feed livestock, creating stronger food security in developing countries. He sees a shift to his burgers will thus help feed millions of hungry mouths.
