The bigger the brain, the better the reflex ability of predators

Carnivores with larger brains similar to body size will be able to reflect and handle situations better.

In a new study published in the journal Proceedings of the National Academy of Sciences on January 25, scientists from the University of Wyoming, USA, conducted a large experiment, analyzing the ability to reflex and process. The situation of 140 animals belonging to 39 carnivorous mammal species lives in 9 different US protected areas.

These animals have 30 minutes to remove food from a metal box that is locked. The size of the box as well as the type of food in it varies according to the size and taste of the animal.

The studied animals are diverse from polar bears, Arctic white foxes, tigers, otters, wolves, and hyenas to a number of rare animals such as the civet, snow leopard and short-legged ferret.

The results showed that 35% of these animals, ie 49 individuals of 23 species completed the task, in which the bear had the best results when it only took 70% of the time allowed, on the contrary, the red-bellied civet and the mongoose has no individual to get food.

With this result, the scientists concluded, species with larger brains corresponding to body size are better at reflexing situations than species with smaller brains.

This study offers a rare perspective on the reflexes and handling of predator species.

This result is an important support for the hypothesis that the size of the brain reflects the ability of animals to reflect, handle situations and improve their understanding of why some species evolve with big brains. than.

However, this study also reveals an interesting conclusion, that larger-sized species have lower success rates than small-sized species. This study also shows that the flexibility of limbs or living in groups does not improve reflexes and handling situations.
