🐻 Are dolphin brains bigger than human?

🐻 Why are dolphin brains bigger than human brains?

“ Is there any particular reason that a dolphin's brain is larger than a human's brain? ” It has a large brain because that brain size has evolved to provide the brainpower it needs to survive and thrive in its niche. Of course, that’s the answer for why any species brain is as large as it is. As for why its brain is larger than a human’s, that is likely because it is suffering under the neuron scaling rules of all other artiodactyls.

Yes, they are slightly bigger than human brains.

“Bottlenose dolphins have bigger brains than humans (1600 grams versus 1300 grams), and they have a brain-to-body-weight ratio greater than great apes do (but lower than humans). "They are the second most encephalized beings on the planet," The key here, as in all animals, is the proportion of brain size to body mass.

Dolphins are bigger than humans and also highly social animals. (It has nothing to do with fish eating - sharks have tiny brains). Nor is it to do with cooling. High body temperature and a high caloric diet are needed to support a large brain with its high metabolic rate. Mammals have larger brains for their body weight than cold blooded animals.

The average adult human brain weighs about 3 pounds – the same weight as the average brain of a dolphin (which is also a very intelligent animal). But there are animals with larger brains that are not considered to be as intelligent as a dolphin. For instance, a sperm whale has a brain that weighs about 17 pounds.

This means we can conclude that the structure of the cetacean Whale and dolphin brain does not endow them with the “hardware” necessary for the production of behaviors that are more complex than those seen in many other animals, unlike humans. So, if the cetacean brain is not large for intellectual purposes, why is it so big? Cetacean brains became truly large around 32 million years ago, about 20 million years after they became fully aquatic mammals. At this time, there was a major ...
