correlation studies
Dolphin is smart because it has a developed brain and many ditches. The more ditches, the more developed the intelligence. The average brain weight of adult dolphins is 1.6 kg, that of humans is about 1.5 kg, and that of orangutans is less than 0.25 kg. In terms of absolute weight, dolphins are the first, but in terms of the ratio of brain weight to body weight, human brain accounts for 2. 1%, dolphins 1. 17%, and orangutans only account for 0.7%.
In addition, after in-depth research, scientists have found that there are significant differences in sleep between dolphins and land mammals. The sleep of land animals, including humans, is generally divided into two different stages: slow phase and fast phase. When such animals or people fall asleep, they first enter the slow phase, then gradually deepen, and after a period of slow phase, they turn into the fast phase, thus completing a cycle.
Different animals have different fast sleep times. For example, people sleep for half an hour. The two hemispheres of dolphin brain sleep alternately. When the right hemisphere is in a state of inhibition, the left hemisphere is in an excited state. After a period of time, the right hemisphere enters an excited state and the left hemisphere is in an inhibited state.
