& # 39; World's First & # 39; footage of mother and child chimpanzees catching crabs in nature



Chimps like seafood too! "The world's first" footage of mother and child chimpanzees that catch crabs in nature reveals a human trait that experts say may have helped our ancestral brains develop.

  • Research teams from the Kyoto University in Japan are behind the latest findings
  • The observed chimpanzees in the Nimba Mountains in West Africa
  • The results suggest that early humans may also have obsolete fish for nutrition
  • Experts say that their nutrients may have helped our higher reasoning powers

Fascinating footage shows chimpanzees catching crabs wildly, behaviors that experts say may have triggered brain development leading to the modern man .

Experts say cut the first evidence of chimpanzees that catch and consume freshwater crabs.

The primarily fruit and nutritious primates seem to have learned to put their hands in the water to catch and eat aquatic life.

Nutrients they have received may have accidentally supplemented their diet with essential ingredients for brain development, researchers say.

A team from Kyoto University observed year-round, primarily fishing between female and infant swamps in the rainforest of the Nimba Mountains in West Africa.

& # 39; The aquatic fauna, our ancestors probably consumed, provided important long-chain polyunsaturated fatty acids required for optimal brain growth and function, the first author said. Kathelijne Koops.

Dr. Koops from the University of Kyoto's primatology and science graduate program said this was important for brain expansion during human development.

& # 39; In addition, our findings suggest that aquatic fauna may have been a regular part of hominine's dietary habits and not just a seasonal withdrawal meal, "she added.

WHAT SHOULD A CHIMP ABOUT OUR EARLY ANCESTORS?

According to the study, the aquatic life of the business may have inadvertently supplemented their diet with essential ingredients for brain development

The team mainly observed female and infant chimpanzees that caught and ate The crabs, while the males were "least likely" to eat shellfish favorite ants instead.

The team believes this is due to the fact that the protein and salts for women – especially when pregnant or breastfeeding – and for the cultivation of young people are important.

The aquatic fauna of our ancient ancestors probably consumed essential long-chain polyunsaturated fatty acids required for optimal brain growth and function and ultimately leading to human development.

The study started in 2012, when the researchers first observed chimpanzees fishing for crabs.

They documented these chimps' demographics and behavior for two years, while analyzing and comparing the nutritional value of the crabs with other foods in the chimpanzee's diet.

Experts learned that crabs not only took place year-round – regardless of season or fruit availability – but chimps & # 39; favored seafood to eat ants, another diet stapler.

They found out that mature males were least likely to consume aquatic fauna and more likely to eat ants.

& Energy and sodium levels in large crabs are comparable to ants, & # 39; added Dr. Koops.

& # 39; This led us to hypothesize that crabs can be an important annual source of proteins and salts for women – especially when they are pregnant or breastfeeding – and for growing young. & # 39;

The study further sheds light on our own development by showing that fishing behavior must not be limited by habitat as originally assumed.

This is not the first case of non-human primates eating crabs, said senior co-author Tetsuro Matsuzawa.

But that is the first proof of monkeys other than humans doing it. & # 39;

In particular, it was earlier observations from aberrates in places in accordance with aquatic faunivory – lakes, rivers or coastlines – and not in closed rainforest.

& # 39; It's exciting to see such behavior that enables us to improve our understanding of what drove our ancestors to diversify their diets.

The full results of the study were published in the Journal of Human Evolution.

WHO IS SMARTER: CHIMPS OR CHILDREN?

Most children exceed the level of intelligence of chimpanzees before reaching four years.

A study conducted by Australian researchers in June 2017 tested children for foresight who are said to distinguish people from animals.

The experiment saw the researchers a grape through the top of a vertical plastic Y-tube.

They then monitor the reactions of a child and chimpanzees in their efforts to grasp the grape at the other end before it hit the floor.

Because there were two possible ways in which the grape could leave the tube, the researchers examined the strategies the children and chimpanzees used to predict where the grape would go.

The monkeys and the two-year-olds only covered a single hole with their hands when tested

. But at four years, the children had developed to a level where they knew how to predict the outcome.

They covered the holes with both hands and caught what was lost through each time.
