Why do young people take longer to learn to walk than other animals, does that have anything to do with the size of our big brains? "
John Bock, an anthropologist at the University of California, Vol.
A young horse can walk within an hour of its birth, and the newborn baboon clings to his mother's hair as it moves through the trees. Even for the most advanced species - monkeys and baboons - their children are more agile than their human counterparts. This is because young people are born With very immature brains, which makes them little able to control their movements, this unique characteristic of man was the result of a long evolutionary battle between large-sized brains and narrow basins
One of the first traits that distinguished people from our ancestors was walking upright, ie on legs only.
There are many hypotheses about the importance of this characteristic, but they seem to have provided a way to move more efficiently in open environments, such as savannah forests.
Although the brain is very similar to that of ancient ancestors and monkeys, it changed the shape of the pelvis until it became modern. This change in shape was accompanied by a narrowing of the birth canal, making birth more difficult.
At the same time, the new approach has helped to walk and move in a great way to access resources and negotiate social relations with those who have flexible behavior in problem solving.
Over time, because of natural selection, the size of the brain has increased in the old man, but at some point, the increase in the size of the brain was met by the problem of the narrow pelvis gradually, as the size of the heads of children increased in the birth canal to kill both mother and child.
Although natural selection does everything in its power to adapt, for example - the children's heads are squeezed when they make their way through the pelvic bones - there is not enough room for a large, mature brain to pass through.
As it turned out, the evolutionary result was to allow the brain to continue to grow outside the uterus before it was cooked.
Unlike other mammals, humans have little development to do after childbirth. The result is that newborn babies need much care and can serve themselves much less than other newborn primates do. <<
