Why is the human brain more powerful and capable of more functions than other animals with larger brains?
The brain of an elephant is much bigger than ours, however by comparison to body weight, it is very small. An elephant’s brain weighs only 0.08% of its body weight whilst the human brain weighs 2% of total body weight. Many scientists believe it is this calculation that determines intelligence however a tree shrew has the highest brain to body weight at 3% of total body mass. The human brain has evolved over thousands of years and now contains “new” areas that regulate and control unique human functions of intelligence.
