With all the advances being made in the fields of science and technology, it may seem that human intelligence is at its peak. A new research shows it’s not. Study says that human intelligence reached its peak two to six millennia ago.
The study was carried out by Gerald Crabtree, a geneticist at Stanford University. He reached the decision by measuring the activities of the brain. He explains, the brain is a complex thing and its activities are relied upon correct functioning of many genes. The more a brain functions accurately, the more the outcome will be.
Crabtree pointed out that our ancestors’ brain were able to function perfectly as they had to use their entire brain before executing any work. But with the blessings of technology, we modern people have become idle compared to our ancestors. Technically, Crabtree concluded that we are dumber than our ancestors. He has written a paper that has been published in two parts in Trends in Genetics.
