It is easy to associate the rise of humanity with our ability to think, to hunt and to compete in technology, as the dominant species of human beings in the world. But new research suggests that softer skills are the reason for our success: especially our ability to collaborate and share, especially when it comes to raising children.
Karen J. The most important difference between us and other apes, according to L. Kramer, is that we have more children and share jobs, childcare and food. Kramer points out that although population explosions are associated with the industrial revolution, humans are already a very successful species, with more than 1 billion people, present in almost every terrestrial environment on Earth.
The study was based on Karen E. L. Kramer based on various studies of the Mayan farming community on Mexico’s Yucatan Peninsula and the Savannah Pume Hunter in Venezuela. The study found that sharing childcare responsibilities could increase the number of children a community could raise and accelerate population maturity and fertility. Her research also shows that sharing food with parents and siblings is a factor in human success.
During her time with the Mayan community, Karen, L. Kramer compares individual contributions to families and communities with consumption. Her findings suggest that Mayan children between the ages of 7 and 14 work two to five hours a day, while children between the ages of 15 and 18 work 6.5 hours a day, the same amount of work as adult parents. Among them, older children tend to help grow crops and prepare for housework, and younger children are more likely to help with childcare. Karen L. Clay defaulted that if mothers and adolescents didn’t cooperate, there would be far fewer children that mothers could raise in their reproductive careers. The power of intergenerational cooperation enables parents to raise more children than they do on their own. ”
At the same time, a study of Venezuelan Savannah Pume hunters found that cooperation between different ages helped reduce the risk of high mortality. Challenges for Venezuelan Savannah Pume hunters include seasonal malnutrition, but sharing food allows mothers to have children at a younger age, which helps them survive in a high-mortality environment. To sum up, Karen L. Kramer found that with the help and cooperation of the surrounding population, human women had twice as many children in the reproductive age as apes. She believes that humans are surprisingly successful apes.
