Big Brains in Animals Come at a Price, say Researchers

It has been suspected for a long time that big brain in animals comes at a price and that is evolutionarily speaking. In order to know more on the same, the study researchers from Uppsala University in Sweden have carried out a research.

In order to reach at a conclusion, the study researchers have selected guppies, which is freshwater aquarium specie. Niclas Kolm from Uppsala University said that their research has been able to prove that bigger brains are expensive and animals with bigger brains also have smaller organs as well as fewer babies.

"We provide the first experimental evidence that evolving a larger brain really is costly in terms of both gut investment and, more importantly, reproductive output", said Kolm. The study researchers have affirmed that their research findings will prove quite important for humans.

While talking about from human point of view, Kolm said that human brain is just 2% of the total body weight, but it does a lot of work, which shows its worth.

Kolm said that they realized one thing while taking out the research and that thing was brain is capable of quick evolution. Large -sized brain guppies were able to perform better tasks than smaller brained-guppies.
